Suunto Spartan Trainer Wrist HR In-Depth Review (It’s a full triathlon watch for $279)

Suunto-Spartan-Trainer-Wrist-HR

I think Suunto finally got their groove back.  After what I’d argue as 1-2 years of being a bit lost, today they’ve nailed it with a product that hits the target audience perfectly and does so at an awesome price.  Actually, I think they hit a pretty massive audience with this watch.

The key piece to know: Suunto just released a full-featured triathlon watch for 279USD/EUR.  Oh – and it even has optical heart rate built into it.  Ignore the 19-word  watch model name, the thing you need to know is that they took the full software of their high-end Suunto Spartan Sport series watch, and then shoved it in a smaller and lighter body, then halved the price.  Oh, and then they took an optical heart rate sensor and jammed that in there too just for giggles.

It has power meter support (both running and cycling power meters), navigational support, multisport capabilities, extensive sport configuration, heck – it’s even got sleep tracking coming up at the end of the month (you didn’t know that was even happening, did you?).  And again, all for $279 – by far the least expensive current-generation triathlon watch on the market.

But let’s not get too far ahead of ourselves.  After all, we’ve gotta pace ourselves given this is an in-depth review.  First up is the usual note that Suunto sent over a turquoise colored Spartan Trainer for me to test out.  I’ll send it back once I’m done with the review, as usual.  You can hit up the links at the end of the post if you found this review useful.  And second…let’s just start unboxing.

Unboxing:

DSC_8953

So let’s get this box all cracked open.  First up you’ll notice it’s essentially the same box as the other Suunto Spartan watches.  Do remember that this is one of a number of color choices for the Suunto Trainer, and thus your exact color scheme may differ.

DSC_8954

For those wondering on colors, here’s the other options.  The ones with the metal bezels cost $329 – so a slight premium. Also, they’ll ship a bit later towards mid-September.

ColorsSpartantrainer

Inside, we’ve got the unit looking up at us:

DSC_8956

Below decks though we’ll find the charging cable and quick start guides/warranty stuffs:

DSC_8960

Here’s everything out on the table:

DSC_8962

Eagle-eyed Suunto fans may have already noticed something interesting: The charging cable.

DSC_8966

This charging cable matches that of the Suunto Ambit series, and doesn’t follow inline with the existing Suunto Spartan series cables (which have a magnetic charging snap).  Side by side:

DSC_9132

Why’s this?  Well, likely because as you’ll also soon notice – the Suunto Trainer looks more externally like that of an Ambit series than a Spartan series, specifically with the small satellite bump on the lower portion of the unit.

DSC_8971

The good news here is that historically speaking we’ve actually seen better GPS accuracy with the Ambit series units that sport the bump than the Spartan series that have slimmed down.

DSC_8970

In any event – on the back of the unit you’ll of course notice the optical heart rate (HR) sensor, which is made by Valencell.  It’s the same sensor as in the Suunto Spartan Sport Wrist HR unit.

DSC_8968

And finally, we’ve got the paper stuffs, a quick start guide in 84 languages and some warranty goodness:

DSC_8963

Overall it’s a pretty slim box – nice and clean.

Size & Weight Comparisons:

So with the Suunto Trainer being a smaller version of the Spartan series, how does it line up in terms of size and weight?  Ask and you shall receive.  First, let’s look at these three models side by side – left to right: Suunto Spartan Trainer Wrist HR, Suunto Spartan Sport Wrist HR, and the Suunto Spartan Ultra

DSC_8976

I didn’t have my Spartan Sport handy, though from the front it’s identical in size to that of the Ultra.  It’s only the weight and thickness that differs physically.

Meanwhile, here’s how thick they all are:

DSC_8978

From a wrist-size comparison, here’s what it looks like on my wrist, which his 17cm (or about 6.5 inches):

DSC_9252 DSC_9251

And finally, let’s look at some weights:

(Left to right: Spartan Ultra, Spartan Sport Wrist HR, Spartan Trainer Wrist HR, Ambit3 Peak)

As you can see, it’s definitely pretty light.  And while some of that is because it’s smaller, it’s also because it lacks the glass front as well as heavier materials used on the bezel.  All of which contribute to a lower weight than the other units.

The Basics:

Suunto-Spartan-Trainer-Wrist-HR-Watch-Face

Given I just wrote about this watch’s near-identical sibling, the Suunto Spartan Sport Wrist HR, I’m going to try and abbreviate some of this.  Everything you read in that review basically applies to this one (except the HR accuracy, GPS accuracy, and screen related pieces).  And given that’s barely two months old – there hasn’t been much in the way of changes since then (beyond minor bug fixes).

Still, I do want to cover the basics of how the watch works to serve as a primer for the sport usage section.

First off, is navigating the menus.  While the Spartan Sport and Ultra had a touchscreen on them, the Trainer lacks that.  So instead you’ll use the buttons like most any other watch.  And in fact, since the Sport and Ultra had these same buttons – it’s really no different than just ignoring the lack of touchscreen.

Wanna understand every menu there is in one handy video? No problem, just watch the below:

The watch starts off on the time screen, which you can lightly customize:

DSC_9154

You’ll press up or down to navigate to different main portions of the menu.  For example, press down gets into historical stats – things like your recovery status, activity tracking, and even 24×7 HR tracking:

DSC_9150

Meanwhile, pressing up goes to areas such the Settings control area, Stopwatch, Navigation, Exercise, and your full sport log.  It’s within Exercise that you’d start a workout (but more on that in the ‘Sport Usage’ section next).

DSC_9165 DSC_9166

For example, in settings you can pair to sensors (and your phone), as well as change options like activity tracker and notification settings.  It’s also where you’ll tweak the watch face.

DSC_9164

Meanwhile, within Navigation you can select routes that you’ve synced to your watch.  These routes can be created on Suunto’s Movescount website, which is actually pretty full-featured for planning routes.  You can even import routes into it, something that Garmin doesn’t permit on their Garmin Connect:

image

And my favorite feature that I love talking about is the heat maps – which are great for planning, especially in places you don’t know.  These heat maps can be filtered by sport – allowing you to get more specific about where you go.  For example if hiking in the Alps near a ski resort in summer, you wouldn’t want to see people’s ski tracks – as those wouldn’t likely match-up to hiking trails.

image

Shifting down to some of the recovery and activity tracking stats, Suunto is still a bit basic here – at least when it comes to the platform as a whole.  On the watch, they’re in the right ballpark.  If you press down once you’ll see your total steps walked on that day.  You’ll also see a halo over it, which is your goal steps for the day (in this case, I exceeded the steps per day goal):

DSC_9036

You can tap the upper left button to swap the display metric and instead show calories burned by those steps.  Pro Tip: The watch doesn’t appear to track steps very well if you’re walking and holding/reading your phone.

You can press the lower-left button to see your daily step totals as well for the past 7 days.  Tapping once more on the upper-left gives you calorie totals:

DSC_9150 DSC_9151

Meanwhile, you can tap the right-center button to see your heart rate for the last 10 minutes.  This heart rate graph though only starts once you press this button.  So you’ve gotta wait about 10 minutes to get the full graph:

DSC_9034

If you press the upper left button though while viewing this graph, you can see the last 12 hours of heart rate data.  This must be turned on in the settings area though, else it won’t show up.  This data is sampled once every 10 minutes, with the ‘once’ part being that it tries for a minute to find a lock on your heart rate.  If it can’t, you’ll get the gaps you see:

DSC_9041

This sampling is significantly lower than most other units on the marketplace, for 24×7 HR.  That in and of itself isn’t actually a huge deal, but rather it’s that it’s just not that reliable.  I’m often missing hours worth of samples, or there’s the simple fact that none of this is recorded anywhere.  So while you’ll see it on the watch, it’s not synced to Movescount (site or app), which is a shame.

Speaking of syncing, the watch can sync via the included USB cable, or to your phone (Android/iOS) via Bluetooth Smart.  The phone app allows you to view completed workouts, sync/change settings, and look at daily stat totals:

DSC_9246

Note that for the daily stat totals, it’s pretty basic here.

With that Bluetooth Smart connection to your phone you’ll also get smartphone notifications on your wrist from any apps that you’d like.  Unlike some wearables that only show missed calls/texts, the Spartan Trainer leverages the standard notifications center control panels, so apps like Twitter and Facebook can show notifications too.  The notifications work well and show up instantly on my wrist as they do on my phone.

With that, we’ve covered all the basics of the watch, now we’ll dive into the sport-specific aspects of it.

Sport Usage:

DSC_9172

Of course, if you’re buying a watch like this – it’s likely for the sport usage.  The Suunto Trainer Wrist HR is incredibly capable when it comes to sports, and this really can’t be overstated.  Unlike most other $300 GPS watches, this has the same software features as their $600+ GPS watches.  And most critically, it’s got a multisport mode and complete sport mode customization.  Most units under $300 don’t have legit multisport mode, so you can’t really use it in a triathlon (they might support each other individually, but not together as one cohesive event).

But let’s not get too far ahead of ourselves.  The watch has a pile of default sports on it, all the common ones you’d expect.  These can be accessed from the ‘Exercise’ menu, allowing you to select whatever floats your boat:

DSC_9205 DSC_9210

The watch contains boatloads of sport modes, most of which are hidden by default.  There’s a crapton of them.  It’s easiest to go online and look at the list on Movescount.  It’s also here where you can create new sport modes to your unit.

image

Each of these modes, once selected/added, allows you to select from any number of data fields and pages.  With the Spartan Trainer, you can select up to 5 data fields per page, which is slightly less than that of the larger-screen Sport and Ultra units (Update: apparently you can do 7 fields as well, I just can’t/couldn’t figure out how to get beyond 5 fields).  The exception to that being the custom interval mode, which gets up to 7 fields still.

image

Also in this same area is where you can customize and tweak the watch at large.  So things like what system you display GPS coordinates in, to whether auto-lap is enabled, or just how you prefer the date and time to be displayed.  Also included in here is the GPS accuracy settings, specifically around sampling rates.

image

All of this is fairly straightforward, and identical to the other Suunto Spartan watches.  Here are the full settings that you can configure.  Note that this only shows a single sport expanded, as getting a screenshot with all sports expanded didn’t really work:

screencapture-movescount-gear-gear2240643-Suunto_Spartan_Trainer_Wrist_HR-1502365914373

Next, let’s head out on the road for a bit of a run.  To do so we’ll start by going into the exercise menu and selecting Run:

DSC_9210

Note that all of the sports more or less act the same way from a structures standpoint.  Obviously things like openwater swim won’t have cycling metrics, but the user interface is effectively the same.

By selecting downwards, you can customize different options, such as doing an interval run.  This is pretty basic functionality, but it actually works quite well.  You’ll specify duration or distance targets for both work and rest intervals, as well as the number of reps.  You can then trigger this from inside the workout whenever you’d like.

DSC_9217

You can also select whether or not you want to set targets (i.e. time goals).  Same goes for if you want to change the GPS accuracy options.

DSC_9218

Later on after the workout, you’ll see these intervals super-clearly within the site:

image

In fact, below the summary of your workout you’ll also see the exact specs of that interval session, which his pretty cool.

image

With all that out of the way, you’ll see the watch has illuminated the icons for GPS status, any Bluetooth Smart sensors, as well as whether it has HR lock.  I cover sensors in the next section.

DSC_9221

Once you press start, it’ll soon show your data fields.  In my unit there’s definitely a bit of a delay between pressing start and seeing data pages, though the timer is counting/recording the entire time.

DSC_9222

You can press the up/down buttons to scroll through your data pages, for example to the lap summary page – which is one of my favorite features on the Spartan series.

DSC_9225

And you can press the lower right button to create a lap, as well as the upper right button to pause.  If in multisport mode, you can use the upper-right button (long-hold) to change sports.

All of this works fairly well, and I had no issues with navigation of data pages or display of data pages.  Here’s a little gallery of some of them.

Now as I said before, for the most part, these different sports act the same (in a good way), so when I switch over to cycling, it all works pretty much the same way here as well.  One of the minor downsides to the Suunto series for triathlon is the lack of quick release kit, meaning while on the bike you need to wear it on your wrist (versus having it detached and placed on your aerobars/handlebars).

After your workout is complete, the watch will prompt you to select how good that experience was.  Like rating a partner in bed, you get varying degrees of emoticons to select from:

DSC_9230

From there it’ll show your hardline stats on the workout, things like summaries and averages.

DSC_9167 DSC_9168

All of this data is, of course, available then on both the smartphone app as well as the site.  The smartphone app gives a similar version to the watch’s display, whereas the site gives you far more details.  Here’s an example from one of my workouts of all the data expanded out.  In this case, I was using a Stryd running power meter with the Suunto Trainer, thus I also get the power meter data.

screencapture-movescount-moves-move170302828-1502321145057

In addition, you can setup automatic sync partnerships to other sites, most notably Strava and TrainingPeaks.  These will then send your workouts over to these sites the second Suunto receives them from your watch:

image

One thing I really like about the Suunto to Strava interface is that I can set all my moves to be private on Strava by default (since my account is private by default).  Whereas Garmin has no such option.

Note that as always, various 3rd party sites treat and process data differently.  For example, Strava reprocesses things like altitude, distance, and even moving time.  They do this for all vendors, so it’s not really a Suunto-specific issue – but just something to be generally aware of.

Sensors & Accessories:

DSC_9129

While the Suunto Spartan Trainer has an optical HR sensor within it, it can also pair to external heart rate sensors.  In addition, it can pair to a number of other Bluetooth Smart accessories as well.  In total, here’s your list:

Bluetooth Smart Heart Rate Sensors
Bluetooth Smart Cycling Speed Sensors
Bluetooth Smart Cycling Cadence Sensors
Bluetooth Smart Cycling Speed/Cadence Combo Sensors
Bluetooth Smart Cycling Power Meters
Bluetooth Smart Running Footpods
Stryd Bluetooth Smart Running Power Meter

Note that it does not connect to any ANT+ devices, nor does it connect to legacy/older Suunto accessories that used private-ANT.  Only ones with the Bluetooth Smart logo will work.

Now when it comes to sensors, you can only save a single sensor of a given type.  For example, if you have a cycling power meter but also have Stryd, then you actually can’t save/pair to both.  This isn’t a huge deal in training (albeit rather annoying), but it is a problem in races, since you’d have to decide which one you want power data from (Hint: It’s cycling).

DSC_9187

Similarly, for dual-sensing power meters, like the PowerTap P1 or Favero Assioma (among others), it will still only pickup a single side of this.  This results in the power simply being doubled, as opposed to correctly capturing both legs.  This is true of the rest of the Spartan series as well.  And unfortunately, it doesn’t identify/list any of the exact sensor ID’s so you have no way of knowing which side (of the two) it connects to.  Nor does it even list brands.

One thing that most other companies do when pairing to Bluetooth Smart sensors is to list the enumerated sensor ID name (often like ‘PowerTap P1L’ or ‘Stryd’).  This includes Garmin on the FR935/Fenix5, as well as Stages on their Dash head unit.  Same goes for Wahoo on their ELEMNT/BOLT lineups.  It may sound like a trivial detail, but it’s actually kinda annoying to use a dual-sided sensor.

In addition to the listed 3rd party sensors above, the Spartan Trainer can also pair to the Suunto Movesense heart rate strap.  While this at its core is a Bluetooth Smart HR strap, it’s also capable of storing and recording underwater swim heart rate data.  Sure, the Suunto Trainer can record this data for you using the optical HR sensor on the wrist, but that accuracy can be more variable, depending on the person, in underwater conditions.

DSC_9130

Whereas the Movesense HR sensor is usually quite accurate underwater.  Note that with the Movesense sensor, it doesn’t display the data in real-time, but will sync the data after the swim.  This is because Bluetooth Smart (like ANT+) is unable of transmitting more than a few centimeters underwater.  Only some analog signals like what Polar uses in certain straps can transmit underwater (none of which are supported outside of Polar).

Heart Rate Accuracy:

DSC_9175

Like the previously released Suunto Spartan Sport Wrist HR, the Trainer Wrist HR  includes Valencell’s optical HR sensor built into the bottom of it.  This is notable because Valencell’s sensor is found in one device that I tend to consider my most trusted optical HR sensor unit – the Scosche Rhythm+.  And thousands upon thousands of DCR readers have agreed – the accuracy of that unit is amazing.  So when Suunto announced they were going with Valencell, that had the potential to be quite significant.

But when I looked at my data from the earlier Wrist HR model, it wasn’t quite as universally awesome as I hoped.  It started off kinda rough, and then over time seemed to get quite a bit better.  Something I have no explanation for (especially since other users had similar experiences), nor did Suunto or Valencell.  So I was interested to see what if anything might be different with the Trainer HR, since it’s a much lighter watch.  Weight can cause bounce of the watch on your wrist in workouts, and thus less weight is better for optical HR sensors.

With the Valencell sensor, the Trainer HR samples and records your heart rate data every second during workouts, as other companies in the market do.  However, as noted earlier, they do not record 24×7 data like some other companies do.  Thus, I’m really just going to focus this section on workout HR accuracy.  Mostly because I didn’t really see any issues with the spot-check HR accuracy mode when I looked at it (non-workout), it generally matched.

DSC_9203

Before we move on to the test results, note that optical HR sensor accuracy is rather varied from individual to individual.  Aspects such as skin color, hair density, and position can impact accuracy.  Position and how the band is worn are *the most important* pieces.  A unit with an optical HR sensor should be snug.  It doesn’t need to leave marks, but you shouldn’t be able to slide a finger under the band (at least during workouts).  You can wear it a tiny bit looser the rest of the day.

Ok, so in my testing, I simply use the watch throughout my normal workouts.  Those workouts include a wide variety of intensities and conditions, making them great for accuracy testing.  I’ve got steady runs, interval workouts on both bike and running, as well as tempo runs and rides.

For each test, I’m wearing additional devices, usually 3-4, which capture data from other sensors.  Typically I’d wear a chest strap (usually the HRM-TRI or Wahoo TICKR X), as well as a Forerunner 935 on the other wrist.  Note that the numbers you see in the upper right corner are *not* the averages, but rather just the exact point my mouse is sitting over.  Note all this data is analyzed using the DCR Analyzer, details here.

First, let’s take a look at a relatively straightforward run, about an hour long, across town and back.  This was mostly stable, with some slight periods of higher effort/intensity mixed in:

image

Overall this looks pretty good (just a brief drop in the HR strap of the TICKR when I adjusted it).  The units seem to very closely match each other throughout.  For example, these short bursts of intensity as I went up a hill are all within a beat or two:

image

Even the very beginning is really good, with both optical HR sensors (Garmin FR935 and Suunto Trainer) matching correctly and picking up slightly faster than the traditional chest HR strap.

There were however two small blips that you’ll see around the 4-5 minute marker, where the Suunto Trainer randomly spikes the HR about 10bpm higher.  It’s unclear what caused these, though it’s something I saw with the early Sport Wrist HR unit.  They only lasted a second or two.

image

Next, another run, this fairly steady-state.  I only note it because of the small oddities at the beginning with the Spartan Trainer.

image

After that point, all is well.  But around the 2-3 minute marker it spiked about 15 or so beats higher than the others, without any real explanation.  But again, after that it was great.  This run was a mix of pavement and trails.

This same sort of variability in the first few minutes is visible on another run I did, mostly steady-state but some ups and downs as it was a trail run:

image

But after that point, it matched really nicely for the remainder of the run.

Finally, let’s look at a short interval run – with significant swings in intensities.  Intervals are of course the hardest thing for optical HR sensors to properly track.

image

What you see above is two things:

A) The Spartan Trainer doing fairly well on the intervals, better than the FR935 easily.
B) The Wahoo TICKR having a rare failure to track on the 4th interval.

Interestingly, I somewhat purposely mixed up the terrain on these short 60” intervals (which start at the 10 minute marker):

#1: Uphill
#2: Mostly flats, slightly down
#3: Mostly perfectly flat
#4: Downhill

As you might expect, it’s the downhill one that has the highest variance, in large part because your cadence is higher – so both chest and optical HR sensors alike will ‘lock-on’ to cadence there.

Next, shifting gears to cycling, how’d it fair there?

This next ride is pretty straight-forward.  The first portion is about 7-10 minutes of me getting to a local park to do loops on the bike.  At which point my intensity stabilizes and I do loops for about 35-40 minutes before returning.

image

So what do you notice?  Again, in the beginning it’s a bit troublesome.  And by ‘bit’, I mean totally off.  However, a few minutes after I start to ride more normally (not stop/go in traffic), it picks up quite nicely and tracks pretty well the rest of the ride.

Still, there are some lags and drops though.  For example this short sprint I did was delayed on the Spartan Trainer (33min marker).  And then following that at one point the Spartan Trainer seemingly incorrectly thought I reduced intensity, yet at another time totally missed my reduction of intensity.

image

Here’s another ride, this about two hours long.  The first 1hr 40mins was largely steady-state, after which it as a bit stop and go as I crossed the city through some traffic, and around that same time I was using a camera/gimbal to film myself.  Interestingly you can see the impact of that a bit:

image

Still, there’s that gap around the 40-minute marker where the Suunto Trainer struggles quite a bit.  However, for a solid hour after that it’s mostly close (save one major oddity around the 1:25 marker):

image

If you look at the 1hr marker you’ll see where both the Garmin FR935 and Suunto Trainer missed a sprint that the traditional chest strap picked up.

Thus, as I’ve said with other optical HR sensors on your wrist – for cycling I’d recommend having a chest strap (or the Scosche optical HR sensor on your upper arm – which seems to resolve these issues).

So overall, it’s somewhat similar to what I saw on the earlier Suunto Spartan Sport Wrist HR – except without all the really bad performance that I saw with that watch initially.  Meaning that in general it’s pretty good, but there are still some little quirks.  Namely in the case of the Suunto units, those quirks for running almost always come at the beginning of the run in the first 3-5 minutes.  While normally you might attribute that to warm-up period, with most of my runs the temperature was 80*F, so temperature-related issues with the skin weren’t likely the cause.

For cycling, it’s about par for what we see with other wrist-based optical HR sensors: Sorta all over the map.  One ride is good, and the next a mess, and the following a total mix.

(Note: I’ll put together my full data-set table of the 8-10 or so workouts that I’ve got here today…just recovering a bit from yesterday’s Giveaway Extravaganza…which only ended 3 hour ago. Smile)

GPS Accuracy:

DSC_9219

There’s likely no topic that stirs as much discussion and passion as GPS accuracy.  A watch could fall apart and give you dire electrical shocks while doing so, but if it shows you on the wrong side of the road?  Oh hell no, bring on the fury of the internet!

GPS accuracy can be looked at in a number of different ways, but I prefer to look at it using a number of devices in real-world scenarios across a vast number of activities.  I use 2-6 other devices at once, trying to get a clear picture of how a given set of devices handles conditions on a certain day.  Conditions include everything from tree/building cover to weather.

Over the years I’ve continued to tweak my GPS testing methodology.  For example, I try to not place two units next to each other on my wrists, as that can impact signal. If I do so, I’ll put a thin fabric spacer of about 1”/3cm between them (I didn’t do that on any of my Suunto Spartan Trainer HR runs – I kept the watches on separate wrists).  But often I’ll simply carry other units by the straps, or attach them to my shoulder straps of a CamelBak.  Plus, wearing multiple watches on the same wrist is well known to impact optical HR accuracy too.

Next, as noted, I use just my daily training routes.  Using a single route over and over again isn’t really indicative of real-world conditions, it’s just indicative of one trail.  The workouts you see here are just my normal daily workouts.

Since I’ve been in/around Paris right now, my runs and rides were a blend of both city running/riding (buildings, tunnels, bridges, etc…), as well as forest running/riding (Bois de Vincennes primarily, also Bois de Boulogne).  I spent a fair bit of time doing trail running routes when able, though I won’t hit the Alps till later this month.

First, let’s just start off with a run.  Note all this data is analyzed using the DCR Analyzer, a tool you can use as well.  Details here. This first run is a bit ‘tough’ at the beginning because it’s in the trails, but also surrounded by buildings on both sides.  A literal urban canyon.

image

You can see that all units were both close, as well as off at times.  The tunnel under the Boulevard proved equally challenging for everyone, with each unit doing their own funky dance around it.  Beyond that though they all performed somewhat similarly in the challenging conditions (not great, but adequate).

Once I got into the more open parks though, mostly running on wider trails, the units became very close.  Note that I wouldn’t ‘judge’ the Fenix 3 used in this test too heavily here.  That’s because I was mainly collecting HR data on it from the HR strap, and thus was hand-holding it.  So it’s likely my grip was impacting it from time to time.  The FR935 and Spartan Trainer were very similar though.

image

image

The pattern was much the same for the remainder of that run.

But what if I went into the trails more deeply?  For that I went out for another run – almost all trail-running except getting to/from the trails.  Check out this:

image

Let’s zoom into some sections around the ‘12th Arr’ text, which is where things really differ.

image

As you can see, things look similar between the FR935 and the Suunto Trainer, but there’s that slight offset, sorta like a shadow.  So again, let’s zoom even deeper.

image

Now this is admittedly pretty darn tricky to figure out.  Since this entire park is mostly just one giant bit of tree-cover, knowing where precisely the trails are is tougher.  Still, the dotted lines help, as do the occasional bits of openness where I can see the trail on satellite view.

Look in particular at the white-circled areas both above.  These are areas where I know my exact path on the trail, and thus can ‘determine’ a winner.  In these case, the Spartan Trainer more correctly was aligned to my path between the FR935 and Spartan.  It was generally the closest.

Except not always.

For example, check out the below.  In this case it’s actually the Fenix 3 that was more correct – nailing exactly where I was.  Whereas the FR935 and Spartan Trainer were offset a bit further in the woods than I actually ran.

image

Next, a quick look at a ride.  Within road cycling you don’t tend to get much in the way of GPS accuracy issues, as your speed is high enough that short of a total GPS failure, you’ll end up with nearly identical results.  For example, look at the high level of this ride.  Things look pretty good, nothing obvious:

image

Since this was a numerous-loop ride, it makes it easy to identify GPS shifting or accuracy issues, especially at the turns.  And even more so because this loop is incredibly precise.  As you can see though, no issues here:

image

Same goes for the other end of the triangle-loop as well, the pointy part.  All the units within what I’d consider a normal range of GPS accuracy (a couple meters off my actual line):

image

So overall no major issues with GPS accuracy – though a few minor quirks that you almost always see in every GPS unit, but that’s not really a big surprise.  With the external satellite bump and similarities to the Ambit3 series (pre-Vertical), we kinda knew GPS was going to be solid.

Of course, that bump may be seen as somewhat uncomfortable for some people, especially those with smaller wrists.  So that’s something to consider as well, whether your trading higher GPS accuracy (slightly) for a less slim watch.

Bugs & Quirks:

Now typically speaking I like to wait till the products starts shipping for an in-depth review.  Where I usually draw the line is whether a unit has final or near-final software (i.e. release candidate software) – as well as final hardware.  But mostly I’m looking for stability.  In doing this for a while I’ve got a pretty good feel for how close to release something is, regardless of what the manufacturer says.

In the case of Suunto, they’re announcing it today, but they won’t start shipping till the end of the month.  Much of this is just the reality of European summer vacations.  So there isn’t much happening between now and then other than people being out of the office.  Hence why I’m reasonably comfortable with where things stand to call this an in-depth review.  The unit I have is a final hardware version, though the software will likely see one last revision over the next two weeks.  I’ll loop back after those two weeks to see if these issues are addressed, or if anything else pops up.

That said, I saw three minor issues that I’ll keep an eye on as it starts shipping to validate they don’t appear:

– On a single shorter activity, the unit restarted: I don’t really know why, but Suunto is looking into it with my log files.  It just rebooted randomly mid-run.  I’ve used it on nearly a dozen other workouts (all longer) and not once did it do this.  I’ll definitely keep an eye out on this one and post if it does or doesn’t occur again.

– When going to start or save a workout it can be slow: Suunto says they’re working on addressing this, but I’m not super-confident we’ll see this fixed by launch.  This is sorta a carry-over of general slowness we see in the Spartan lineup when interacting with the user interface, primarily NOT in workout mode (workout mode is fine, once started).

– Odd Strava/Stryd cadence doubling bug: When uploading a run to Strava with the Stryd running power meter, it doubles the cadence (i.e. to 360 steps per minute).  Suunto is looking into it and suspects it may be a change in the way Strava is handling things (it’s happened previously).

Overall, not too shabby.  Of course, I can only find bugs in the things I’m using in my day to day workouts and scenarios.  A feature that may be my ‘mainstay’, could be something you never ever use.  And inversely, some specific feature combination you use daily I’ve potentially never used in my life.

Comparison Charts:

I’ve added the Suunto Spartan Trainer Wrist HR into the product comparison database.  For the purposes of below, I’ve compared it against the Suunto Spartan Sport Wrist HR, as well as the Polar V800 and Garmin FR735.  It’s not a perfect comparison per se, but it’s in the ballpark in terms of pricing and all being triathlon watches.  You can mix and match your own product comparison tables here, using the product comparison tool.

Summary:

DSC_9235

I’m really impressed.  Not only has Suunto come a long way in a year, but more importantly they’ve identified a gap in the market (full-featured GPS watch at sub-$300), and then went ahead and found the perfect peg to stick in that gap.  The watch works really well and I’d have no issues recommending it.

I think Suunto has effectively done what Polar did when they announced the M400 a few years back: Significantly undercut the competition from a price standpoint, while still delivering a really solid product.

Some might wonder why I think this is such a great watch competitively whereas I’m far less enthusiastic about the Spartan Ultra (or even Sport).  Well, the key word is right there: Competitively.  For $279, this is an awesome unit.  If it were $600-$700 like the Ultra, then I wouldn’t be as excited – because that’s not competitive with the Garmin Fenix 5 that’s in the same price ballpark (or even the Fenix 3HR that’s older).  For $279 I can accept that it might be a tiny bit slower than I’d like to respond than a $500-$600+ unit, or that it lacks proper 24×7 HR data.  But that’s OK I think, it has far more features than any other units within ~$120 or so.

Value and to whatever extent you want to call ‘ratings’, are indeed inclusive of price.  A unit that’s great at $279 would be uncompetitive at $600.  Further, Suunto’s also spent the last year fixing the majority of the issues with the Spartan series, which are included within the Spartan Trainer.  On their higher end units though, they need to go beyond fixing issues and move into innovation.  Still, I think they’re getting there.

Which again – is a really round-about way of noting that the Spartan Trainer Wrist HR is a fantastic value.  You get a multisport watch that’s quite customizable, that has power meter support including running power support, and you get optical heart rate.  Well done Suunto, well done.

    Nice!!!

  3. Imre

    Hi Ray,

    Thanks for the review!
    I find that the HR accuracy part is missing, though!

    Cheers!

  4. Geoffrey

    Hi DC….thanks for the great review. I was curious (maybe I missed it) did you list the available colors for the unit? This might actually lead me to get rid of my Fenix 3 and go this one!!

    • Good point, I just added that in at the start of the unboxing section. I only had the pretty teal version, not the others. But the others look pretty solid, especially the metal bezel ones.

  5. Eric

    What an awesome review, as always. Ray, I have a question for you. I go swimming 3x a week, in an outdoor pool that’s 50m long. I’m currently using an old Garmin Swim to track my laps/distance, but I’ve been on the lookout for a device that’s relatively reasonably priced that could also track my heart rate. I use a Fitbit Charge 2 24/7 but not when I’m swimming since I’m not supposed to. Would you recommend this Suunto for this particular use, ie heart rate and distance/lap tracking during my swimming sessions? Thanks in advance if you have a chance to answer.

    • Geoffrey

      You can use a 4iii Viiiva it can track HR while swimming also. :) I have one and have used it so I know it definitely works.

    • Unfortunately getting to the pool in August in Paris is a bit…tricky. I was hosed yesterday when my pool was closed, so going to try and hit it up tomorrow to look at HR accuracy there.

      In general though, even Suunto (and Valencell) will admit that users will see variable results with their optical HR sensor in the water. For some, it might work just fine. Yet for others it’ll be a complete mess. The technology is just rough there.

    • Eric

      Thanks for your response! I know the issue, I’m in Paris too… but a bit privileged in terms of pool access I have to say…

    • Sweet, you’re offering me your pool pass! ;)

      I found a Twitter post by the city for which pools are actually open in August. So going to start there.

    • Eric

      Well, the club I belong to allows me to invite guests a handful of times a year – happy to let you try it one day if you want!

    • Eric

      Thanks, that’s interesting to know

    • John Patkin

      Geoffrey, I get swim HR data from a ZoomHRV. The measurements are consistent but you can’t get a live reading while swimming unless you carry a smartphone with you. Unless you want to wear a chest strap, there seem to be very few options for wet HR data.

    • John Patkin

      And Ray, thanks for the great review too.

      Keep an eye out for a product from a Hong Kong med-tech company Heartisans. They claim they have a wrist device that can measure blood pressure in the pool!

  6. Steve

    Off topic for this review, but:

    “You can even import routes into it, something that Garmin doesn’t permit on their Garmin Connect”

    Have you ever been able to get anything out of Garmin about why this is the case? I know modern devices can pull courses straight onto the device but if you’ve got anything older than an F5 or Edge 520, you’re flat out of luck.

    • No, I haven’t asked directly that. Though, I’ve talked at length about the whole navigation on GC is a fiasco bit. No real progress though.

    • Steve

      I did start work on a Chrome extension that would “insert” courses into GC but never got further than the proof of concept. Might try and resurrect it, it seems like such basic functionality. And the old “classic” GC used to allow it, I’m sure.

    • Brook

      Also it is worth noting that you can make Garmin auto upload as private – can’t remember if I did it in garmin or strava though.

    • André Lemos

      you can on Strava

  7. Simon Vikström

    Hi!

    Is there any way to get the data out from the device with USB (like a usb mass-storage device) without using suntoo-programs that probable doesn’t work on Linux?

    And if so, does it log into a known file format (like fit, gpx, tcx) or is it proprietary?

    • I’m not aware of anything for Linux.

      On the bright side, once you at least sync it with Windows/Mac/Android/iOS (if you have one of those), then you can grab the standard file formats.

    • Matt H

      Suunto removed the export function from their “mobile” site a whle back though unfortunately (and disabled the “get desktop version” function) – although it does work with the iPad. I find this a real pain when I’m out an about. Apparently it was an under-used function so that they replaced the hiden until displayed screen real estate with “Share as Greatest Move” which I’ve never used.

    • Hansu

      Matt H: At least on Android I can set Chrome & Firefox to request desktop site and I’ve been using that for “Export to FIT” file for manual Strava import.

  8. Alberto Diaz

    I like it!!

  9. tfk

    i’m impressed that you found a tonally matching stone to take some of the images on.

    why do you think they put the valencell unit the other way around compared to the other Spartans.

    • My guess is just internal fit. But I’ll ask, interesting point.

      As for the stone, I only utilize the most fashionable of rocks that Paris has to offer.

    • Andrew Clarke

      Yeah, that is a great photo, including the reflection of the sky off the leaf complementing the colour of the watch, and the “feeling excellent” displayed on the watch.

  10. Dimitris

    Hi Ray

    Thanks for the review. I did not see anything on battery life or maybe it slipped me while reading. Do you have something on this?

    Thanks

    D

    • So it’s 8ish hours in 1-second GPS recording mode, but you can change the GPS recording rates per sport. So for an Ironman you’d want to reduce down the run GPS recording rate slightly to account for that.

      For daily usage with the optical HR sensor enabled in their ’24×7′ mode, I’m getting about 2 days, maybe 2.5 days. Far more if you turn it off.

    • Cody Palosaari

      I love this watch! As lomg as it supports open water and batter can last an Ironman.

      The chart says up to 30 hrs gps, so connecting gps, hr, and using a power meter on the bike will this last 12 hours?

    • Cody Palosaari

      I love this watch! As long as it supports open water and battery can last an Ironman.

      The chart says up to 30 hrs gps, so connecting gps, hr, and using a power meter on the bike will this last 12 hrs?

    • Yes, if you select to reduce the frequency of GPS. The options are:

      8 hrs – Every second
      13 hrs – Roughly every 5 seconds
      32 hrs – Roughly every 60 seconds

    • Cody Palosaari

      60 seconds seems unusable if you care about strava segments or any speed accuracy. Even 5 seconds seems bit too long but Im not sure what most watched have, Ive only used a Vivoactive and Polar m450.

    • Sure, but realistically every 5-seconds would be more than fine in most cases if you’re planning on going 8 hours strong.

      Agree that 60 seconds isn’t useful for cycling or road or trail running, but is fine in certain hiking cases.

    • With only 2 days battery life in 24×7 mode and 8 hours at 1sec recording, I would think the Polar m600 checks a lot more boxes for around the same price (except that this has a “native” multisport mode).

  11. Alex Masidlover

    What are the indoor swimming features like? I notice from the comparison tool the Spartan series seems to have lost the drill mode that the Ambit3 has – I couldn’t sport any screenshots or detail in any of the Spartan reviews (Ultra, Sport HR or Trainer).

    The drill mode on the Ambit3 is quite handy just to get the total distance of the set correct when doing kick sets.

    Also, how do you find the reliability of the Bluetooth syncing? On my Ambit3s; notifications are totally solid (I think that runs as a background service on Android) whereas auto-syncing of workouts goes via the main app and that loses its connection to the watch several times a day for me. Interestingly Movescount 1.3.something + the previous Ambit3 firmware worked perfectly, then they updated Movescount to 1.4 and I went back to having connectivity issues – I report the issues everytime they do a version bump and everytime they say they’re working on it…

    • Žilvinas Grigaitis

      Same question here, would consider upgrading my ambit3 to this piece, but since I spent a lot of time in the pool wouldn’t want to loose drill mode. Any spartan/sport users here can comment?

  12. Hansu

    Hi, I’d like to correct this: “Things like steps and such aren’t carried over to the main Suunto website, and are only on the app.”

    Steps and calories are carried from Spartans to Movescount. You can’t view them by changing the Feeling insight element to Activity using “Change insight element” button in the top right corner of that element.

  13. Matthew

    I would be interested to hear how the plastic screen holds up vs. the glass on the metal bezel models.

    One (of several) things that I found disappointing on the 920 was how easily the screen scratched.

  14. Prado Manuel

    Nice watch!

  15. Marco Epifanio

    Yeah!

  16. Adriaan

    Thanks Ray for the great review!

    This is kind of showing middle finger towards Garmin developers, saying Where is a wish, there is a way…
    I like the heat map on Movescount, as well as the View Flybys on Strava. Garmin is not even close to that function. Actually, their Explore – Activities is not working for months.
    I also like the onscreen device settings and the price as well!
    In my opinion the continuity is the reason why most of the athletes stick to Garmin. Myself since 2010 the same year when I became a DCRainmaker reader…
    If I was a newbie in sport and have to select a device, I think Garmin would be the last choice.
    And thanks to opening my eyes and pointing to the actual market leaders at development.

    • Yeah, it’s funny, each sites has pros and cons.

      For example, on the Suunto side they handle advanced data better in terms of plotting/charting. And of course navigation/course related elements.

      Whereas Garmin on the other hand easily beats them on things like 24×7 activity tracking (steps/heart rate/sleep/etc…). Also has more partners for 3rd party sync (a lot more).

      Then you get into personal preference items. For example Suunto allows you to change settings on the site, but generally not on the watch (i.e. data fields). Whereas Garmin is the opposite.

    • Adriaan

      This is how I actually see Garmin in relation to it’s competitors (no offense to Toupalik):

      link to youtube.com

    • On some levels, probably true about how they feel about it.

      On the other hand, from a business standpoint they outsell virtually all their competitors in almost every category (except Apple Watch and Fitbit), so by pure race examples it’s kinda true.

      The good thing though is that it’s more than one race. Like racing bikes, there’s a new race all the time, and new kings and queens are crowned and lost all the time.

  17. Stoffel

    “if you have a cycling power meter but also have Stryd, then you actually can’t save/pair to both”

    I get that you definitely can’t use them both during a multisport activity, but does this mean the watch can’t ‘remember’ both? So do you have to re-pair the cycling power meter each time again after using a running power meter in a previous activity, and vice versa? Is this also the case for the other Spartan models?

    • Correct on all assumptions unfortunately.

      In talking with them yesterday, they understand this is frustrating and it’s on the list to resolve. It’s sorta a bigger issue though around sensors and sensor management in general though (or lack thereof).

  18. Kyle

    Ray, when will Suunto give waypoint distance calculated via the imported route and not just “how the crow flys”. I dont understand why this isnt brought up more. Makes zero sense when you import a route and it still give you a straight line distance.

  19. Steven Limmer

    This is a very cool watch, however my comment is about the comparison chart – V800 is noted as not having an interval feature on-watch. This isn’t the case anymore; you can create basic interval sessions by time/distance on the fly.

  20. Thanks for the review Ray! Good to see Suunto competing in the price range.

    You might want to fix your comparison chart 3rd column headings – should say FR735?

    • Thanks!

      Weird, looks like a product ID digit was missing, so it wasn’t showing the FR735. Should be good now. I was looking at that this morning around 4AM trying to figure out why the digits looked too low (usually 5-digit ID’s), but my brain was just shot.

  21. Patrick McCrocklin

    I need this!

  22. Nicky

    Hi Ray,

    Seems really interesting this watch.
    I have a quite specific question regarding HR accuracy. I’m a spinning instructor, so I do quite a bit of workouts on indoor bikes. Did you try this watch in indoor circumstances, and how’s the accuracy there?
    And a second bit more general question, but still linked to indoor cycling/running, Which watch would you consider these days most optical HR accurate of indoor activities?

    Thanks a lot!

    Nicky

    • Yup, got some indoor workouts – and no issues there. In general though, I rarely see issues with optical HR sensors indoors on trainers/bikes. The main reason being you reduce the road vibrations – and thus most of the issues go away.

      I’ll try and pull the indoor workouts into the table later this evening.

  23. Tim Shears

    Hi Ray.

    Any thought on this watch’s suitability for open water swimming. It seems to have the Trsining Peaks and Strava connects that I want, but I cannot see anywhere in the review as to whether the accuracy is good enough for swimming outdoors.

    • I wasn’t able to test it yet for openwater swimming. My options are pretty limited here, though I may slip away this weekend or next week to try it out. At worst on the 20th or so I’m at an openwater swimming locale.

    • Tim Shears

      Great, thanks. I can wait till the 20th. 😀

      I looked online and it seems they are pre-order only ATM anyway.

      It would be so nice not to have to measure/guess my swims after the fact using Google Earth.

  24. Mike Serago

    Cool thank you

  25. Matthew B.

    A couple questions:

    – This has navigation, but no magnetic compass?
    – Can it charge while an activity is running?

    • Dimitrios Kanellopoulos

      It has navigation with no compass via bearing.

      It can charge while it’s recording but its not the most easy thing to do

  26. Robert

    Hi Ray, does this offer intervals by pace target, like Polar and Garmin?

  27. Chris

    Nice product!

  28. Fran

    LOL, loving the comments that think you are still giving one of these away!! Awesome review, although Suunto is not my thing… and great giveaway day, thanks for that and I keep my fingers crossed!

    “One thing I really like about the Suunto to Strava interface is that I can set all my moves to be private on Strava by default (since my account is private by default). Whereas Garmin has no such option”

    ?

    I sync all my data from Garmin – and they automatically appear as private (easy to make public) in Strava.

    I have “Private Activities” ticked on:
    link to strava.com

    that’s obviously a strava option not a garmin/suunto one. Does this not work for you ?

    • That’s a fair point I hadn’t thought about. Especially since it would only impact new activities. Might do just that…

      (The obvious reason I do this is simply that I’m usually testing new things, or often have stupid 5-second long workout type uploads when shooting videos and such. Usually new things don’t get identified by Strava, since that’s a manual process on their side – but the short workouts would be nice to avoid getting kudos/comments on.)

    Hello D.C…..

    Actually I have a Suntoo ambit 3 sport, works great for me, you thing I should upgrade to this watch?? It is worth the upgrade?

    • Honestly, I’m not sure that makes a lot of sense unless there’s some very specific Spartan Series feature you want (i.e. color screen, lap summary page, or vibration alerts).

      Else, you’ve probably got more features (like apps) on the Ambit 3 than you do here.

    • Jacobo

      Thanks, you are always a great help

    • Adam

      Ray, is the support for Suunto Apps foreseen for Spartan series at all?

    • Longer term perhaps, but I’m not suspecting short-term.

      I noted to them when I met with them back in April that having a platform of some sort will become critical for them longer term. As watch platforms (i.e. Garmin’s, likely Fitbit’s, etc…) grow, it becomes more and more important. In the same way now that it’s impossible to imagine a smartphone without the ability to install apps.

    • Bartek

      What about if I have an Ambit 2 Black. Do you think that this update is worth the price?

  34. Rupert Nanni

    Thanks Ray. Wouldn’t buy anything without checking with you first!
    Do you think this watch will pick up power and speed/cadence from an indoor trainer when paired with a 4iiii Viiiiva?

    • Hmm, I don’t remember hearing of any Spartan issues with the 4iiii Viiiiva (which this platform shares). I can try it out tomorrow though.

    • Rupert Nanni

      The 5K Runner tried with a 4iiii and a Spartan Sport a couple of 4iiii software versions back from today’s version and managed to get power (all be it a wee bit delayed) to show up on the watch as well as intermittent cadence from his smart trainer. It’s always been a problem for Suunto since they went bluetooth only.
      Would love it if you tried …..

    • Yup, will try and remember tomorrow when doing some trainer stuff.

    • I never had luck with Viiiiva and SSU or SSWHR. It’s been a while since I haven’t tried again, though

    • Rupert

      News for Spartan + Indoor trainer people. Did some work yesterday and have got the Spartan to get all of the data from the smart trainer. Like Eduardo I couldn’t get the Viiiiva to work but I have got the CABLE to work. I think this might be because the Viiiiva can’t convert FE-C to BT. only the older plain Ant+. When I configured the CABLE yesterday, it did a software update and bingo – speed,cadence, power, distance everything showing up on the Spartan.
      One thing you have to take into consideration is that the Spartan doesn’t show what sensor it has connected with (please Suunto, give them names). It just says Bike Pod or Power Pod so it’s possible that during the pairing process your watch is connecting to the trainer and not the CABLE. To get around this, I moved slightly away from the trainer and held the CABLE on the screen of the watch so that it was definitely the strongest signal while the watch was pairing.
      Picture shows a brief Movescount download while spinning the crank by hand. All data present. Only downside is that the CABLE goes through batteries but I can live with that if it works. I believe BT 4.0 will solve this issue of only being able to pick up one signal at a time.

  35. Tim Grose

    “Note that it does not connect to any ANT+ devices, nor does it connect to legacy/older Suunto accessories that used private-ANT. Only ones with the Bluetooth Smart logo will work.”

    I think this is important to note. Often, say on the bike or on Zwift, I like to pair to both my watch (for backup and to to use the training load features say on a 935) but would use an Edge or Zwift itself as my main display. That works fine with ANT+ but with BT you need to choose which one you want to pair to.

  36. Ida

    I love the white and gold edition! It’s a limited edition right? Is it going to get difficult to get a hold on it? I live in Norway. I personally don’t like any of the other colors, I really want to get the white and hold one!

  37. Martin Kuiper

    Looks good.
    Pitty I just swapped from my ambit 3 for a polar v800 (for about 350 USD).
    How does the size compare to a v800?

  38. ivandobski

    How are the general smartwatch functions – sms/calls etc?

    • I’ve had zero issues with smartphone notifications – something I can’t say was always the case in the past with other Spartan units.

      At the same time, I think that’s more them maturing the platform as a whole.

    • Tyler

      Could you please include some photos of the various smart watch functions?

      Like how readable text messages are, can you reply from the watch, music player controls, calendar view, weather view, etc.

      To me, Garmin or anyone else could really broaden their appeal if they’d just put a little effort into this stuff, and maintain it.

      My Garmin vivoactive (the original small one) was darn close to perfect on this stuff, but they’ve completely abandoned it with software updates, and it appears that slim watch style was a one-and-done.
      The Forerunner 35 text message notifications should be better, but don’t really work at all, and it also disconnects bluetooth constantly.

    • Cody Palosaari

      @Tyler, agree, the original Vivoactive is a great smart watch, and the best looking triathlon watch. There are some apps that let you reply to texts on the watch too. The new version is ugly so wont even look at it. Was hoping for a vivoactive 3 that goes back to the original form and adds open water swimming gps,

    • I’ll take some photos of the smartphone notifications in the morning. There’s actually one coming in a time or two within the menus video, fwiw.

      The unit doesn’t have music control, calendars, or other features you noted. Hence why I didn’t take photos of them. ;)

  39. Stuart

    Tyop alert: “support each support”.

    Looks good. It’s a bit of a pity that the Vectors are ANT+ only; that kills this watch for me (if I were in the market for a new watch, which I’m not; the 735 is working fine for me at the moment.) Still, competition in the marketplace can only be a good thing.

  40. Leigh

    Do you have a picture of this in your wrist? Is it small enough to fit a woman comfortably? The Spartan Sport is way too big so I was hoping this model might fit the bill. Thanks!

    • No problem, just added pics of my wrist to the size & weight comparison section. I’ll add pics of it on The Girl’s wrist when she gets home later tonight. She’s pretty small – both in height (5’2″) and wrists.

      She did try it for a few hours one day on one of her workouts. She found it a bit more uncomfortable than the Fenix 5S she wears, primarily because of the bump. But it’s also possible she’d get used to it over time too.

  41. dan

    Is it possible to use a consistent color for each device in your graphs, or is that something that isn’t supported by whatever software you’re using? It’s mildly annoying that the line for the Spartan Trainer is Blue, then Purple, then Brown, then Blue again, now Brown, suddenly Green, then back to Purple, to Blue and finally Brown one final time.

    • Yeah, it’s kinda tricky. For each run/bike/whatever it’s effectively a new set in the tool. So while I can set the colors manually per set if I remember, I usually forget.

      Unfortunately setting the colors per device across the entire platform would quickly run into conflicts with the number of devices I use. :(

  42. Mr T

    Any word on if this works with MilestonePod?

    Im glad to see a company that doesn’t look at its customers as $$$. I feel that garmin is becoming a high end sports watch maker. A lot if people don’t have $600 to drop on a new watch every year (although I know the Fenix appears to be selling well)

    • I just tried it.

      Pairs just fine as a footpod, and then doing a super-quick indoor test run of swinging one shoe without the watch moving (to validate it’s not using WDR from the wrist), it accumulates distance and shows a seemingly valid pace.

  43. Patrick

    Do you think Suunto will ever add the custom app feature back like they have available for the ambit? That’s the only reason I haven’t upgraded from my ambit 3.

  44. Karl-Henrik Sundberg

    Great review!
    Smart Notifications: Having read an incoming notification on the watch, will that mark the notification as “read” on my phone?

  45. Melina

    Great Sunto! 👏🏻

  46. Jon Rune Trengereid

    Did you connect a power meter to the watch and it worked? Just asking since it says no support for power meters on Suuntos website.

    • Yup, a few rides in fact with different Bluetooth Smart power meters. Suunto is aware of the mistake on their site (it was in some other materials as well). They confirmed numerous times via e-mail chain it does support power meters, and I’m able to confirm that in the unit itself.

      As noted in the post though, there are some limitations there – like I talked about with the whole left/right thing, as well as only one power meter per device (meaning, no running and cycling power meters both saved).

  47. Josh

    What is the best choice in your opinion for cycling speed and cadence sensors on this device and the Ambit 3 assuming one isn’t using a power meter?

    • I’d generally go with the Wahoo sensors. I personally prefer when possible using a combo speed/cadence sensor when on BLE, since it seems to be better supported by more devices than individual speed or cadence sensors.

    • Josh

      As I am slightly new to these sensors does that mean that the Suunto magnetic sensor is the one you prefer versus magnet less?

    • I prefer magnetic in general, primarily dual ANT+/BLE. I haven’t tried Suunto’s BLE-capable ones.

    • Josh

      Got it, in that case now I understand I believe the product you are referring to. Just in case, are you able to email me a link to it so I can buy thru CT or Amazon.

  48. Hubert

    Great review Ray, super happy to see the pricepoint/features ratio, quite amazing!

  49. I’m still waiting on Strava to correctly output Suunto’s swims. If I swim in a yard pool, Strava thinks a Suunto is in meters, then takes THAT number and converts it from meters to yards. I’ve bugged them about it for over a year and they won’t do squat about it.

  50. alexei

    hi there ray
    whats the scren resolution?
    have you tried open water swmming or swimming at all?you think drill mode would be implemented later?
    on triathlon mode it does automatically add transitions?
    maybe is cheaper becase now these are made in china?

  51. Christian G. Garcia

    Hey, I would like to insert my similar question here:

    I have an Ambit2. My main interest is capturing trekking routes online to follow them with the watch. I do have a very thin wrist and the Ambit2 size bothers me a little. Will this new model answer my needs?

    Thanks and congrats for your impressive work.

  52. Andrew

    Hi Ray, have you ever thought about adding the ability to broadcast HR to your comparison charts? I run with a fenix 3hr, but I bike with a bike computer and broadcast HR from my watch to the edge. I don’t think I’m that unique of a use case. Anyway, thanks for the great work.

    • It’s definitely on my list actually to add. Maybe this weekend. It’s a 5-second thing to add to the database. It’s a multi-hour thing to go back and update old products to ‘No’. :-/

      There’s a few other things I want to add and/or remove from current listings (like the pre-BT 4.0 thing doesn’t matter anymore), and so on. Inversely, with watches now having NFC payments, that’s also something to consider.

  53. Pete Parfitt

    Just a quick question. Do you know if it is possible to create a custom multi sport event that isn’t standard swim bike run, so for example a cross train/row/run style workout in the gym.

    • Not a problem. If you’d be happy with the (lower) amount of data you can get from a multisport ‘move’ rather than individual ones may be a question, though

  54. Looks like a good time, what with the upcoming updates, for the new-and-improved how-to/manual I’m preparing for the Spartan Ultra. After all, if the Spartan Trainer means Suunto has got their groove back, that means that the SSU is also getting groovy. Same software (platform) and better hardware, except for the oHR, on the SSU, after all ;)

    • Perhaps, but keep in mind as I talked about in the concluding paragraph that price is a really important piece of it. What makes one product great at one price point may make it less desirable at another price point. And of course, hardware features are a piece of that puzzle (like OHR).

    • Of course, but the other Spartans have also come down in price already, risen in features and functionality…

      It’s quite an amazing market anyways. I’m just now working through the Casio ProTrek Smart (first videos on my YouTube, in-depth review coming up in a bit). At $500, is that now expensive or not? Compared to a SSU? Compared to a Casio Mudmaster (~500 for just ABC, not a smartwatch, but “Tough”)?

      And there’s so much looking at feature lists, but much less at actual needs. Great triathlon functions would be lost on me, but I need the battery. Same with oHR (though 24/7 tracking would be tempting.)

      Well, we’ll see. I’m miffed Suunto doesn’t want me to have an early review, too – and kinda happy I can return to the SSU with updates rather than chase the “I’m the first review”-game. Brings advantages in reader numbers/attention, though :-p

  55. Chris Barber

    How many people must seriously look at watches like these but then read that they don’t work with ANT+ devices and discount it as an option immediately as they don’t want to upgrade existing (expensive) devices?

    Surely it’d be worth including ANT+ compatibility?

    • I’ve no doubt it impacts sales (less now than it did with the Ambit 3 series – which is where I’d say Suunto lost a huge chunk of the triathlete crowd).

      I did actually note it within the sensors section, as well as again in the comparison tables.

    • Cornelius Puiulet

      I noticed you mentioned the Suunto Trainer can’t pair to multiple power meters or hr transmitters. Basically I would have to delete a power meter to pair another one. Or delete a HR transmitter to pair another one. Im guessing the same would apply to speed and cadence sensors. That’s a no, no for me. Why is Garmin so much more in tune with what athletes need than other serious multisport companies like Polar and Suunto? I really love the look of the Suunto watches, but there just not competitive with the top of the food chain Garmins. Like the 935, (which I own) or the fenix 5.

  56. Hm, the charging cable and port looks a lot like the one from the Traverse. Are those compatible? Just curious, I’m very glad about the Traverse (Alpha) and wouldn’t trade with something not having barometer and can’t take a beating ;-)

  57. Casey Cook

    Wow Giveaway still going??? This is awesome…..oh wait…never mind.

  58. Thanks for the review. In the market now looking for a new gps sports tracking device.

  59. alexei

    money aside…what would you choose between this and the spartan sport wrist … gps wise?

    • My Suunto Spartan Sport Wrist HR GPS testing showed that it’s pretty similar to this. In general quite good, but both units can certainly have their bad moments (like any GPS unit).

      I’d personally choose this just because it’s smaller. But that’s because I like smaller watches in general.

  60. SS76

    I suspect having the sport mode “obstacle” would be the best option to use if you were using this for soccer?

  61. Chris Gasken

    Woooow there… ” it’s even got sleep tracking coming up at the end of the month”. Is this in the next Spartan series update? DC rainmaker, you holding out on us? Do you happen to know what else is in this update???

    • The existing Spartan series will get it, though slightly behind the Spartan Trainer. The Spartan Trainer should get the update on August 31st, with the other Spartans “about a month later”.

      It’s not in my unit, and it’s plausible that it might not be in units on Aug 31st for purchasers if the feature slips a bit.

  62. Thomas

    So the menu has a 24/7 HR tracking option? This is interesting, I tried to look it up on the suunto page but it doesn’t mention 24/7 HR tracking. Do you have any additional information about the 24/7 HR tracking?

    • I talk about it a little bit up above. But in a nutshell it attempts to find a HR pulse every 10 minutes, and saves that to memory for up to 12 hours. If it doesn’t find the pulse within the 1-minute span (each 10 minutes), it gives up till the next time.

      None of this is saved to the site/app/etc… it’s only visible on the watch.

    • Thomas

      Thanks for the quick reply. Apologies, I completely missed that part in the review.

  63. tman

    is this going to look stupidly small on my (a bit skinny) wrist? Do you know the face width please?

  64. Simon Carney

    As one previous reader mentioned, the broadcast HR facility on watches is really important and becoming more of a problem for indoor training now that many iOS programmes no longer facilitate the use of the ANT+ dongle on an iPAD and require a BLE signal from both the trainer and HR device. As such, i have to use a Wahoo chest strap (hate it), Mio Fuse (broadcasts in both Bluetooth and ANT+ – but non-functional as an everyday watch) or else a Vivoactive HR or Fenix 5 with a CABLE device to convert the ANT+ to BLE via my iPhone (CABLE works well but chews batteries and major PITA). Does the Suunto broadcast HR? and if so, which formats?

  65. Yannick

    Hi Ray!

    Thanks for another solid review! The Suunto Spartan Ultra has been a major disappointment for me last summer (I replaced my Ambit 1st gen by an Ambit 3 Peak instead) so I’m very cautious with Suunto now. I’m glad to see they seem to be back to please athletes rather than rich people who want new techy toys.

    About the Stryd doubling bug… I asked Stryd once on their LiveChat why my data showed a correct cadence (as measured by the Stryd foot pod) in Movescount but a value cut in half in Stryd’s power center. I have not kept a copy of the exchange with their tech but their answer, as far as I remember, was that the pod itself (i.e., not the Stryd app, which lets you select between spm/rpm in the settings) measures in rpm “because that’s what athletes prefer”… or so they said. Since I never run with my phone, my cadence data in Stryd’s Power Center comes directly from the pod through the mobile app when I upload the power data after my run is over, and it shows as a value of 75-90; in Movescount, however, the cadence is likely “converted” in spm by multiplying the foot pod cadence data by two since the values are 150-180 (although it looks redundant to upload the data from the foot pod when the pod is paired to my Ambit 3 Peak, doing so allows me to see power data when the Stryd pod fails to properly transmit power data to my watch, which has happened more often than it should imo)

    Between the firmware updates of the Stryd pod and app and the newer Suunto watches that are now fully compatible with running power meters, could it be that the data from the Stryd pod is still automatically doubled somewhere in the Suunto interface??

    • Yeah, Suunto and I were discussing that as a possibility – but it actually shows correct in Suunto’s interface. It’s when it gets sent to Strava that it goes askew.

    • nkofahl

      I had a similar issue with the Wahoo Tickr X. When I first got the Tickr X, I captured a few runs with their Wahoo fitness app to see their run dynamics. When these runs were synced to Strava cadence doubled. Strava appears to be aware of the issue. They may have even fixed it, but I haven’t messed with the Wahoo app in quite some time. Interestingly enough if you pair the Tickr X directly to the strava android app, it shows up as a cadence source and reports correctly the run cadence. I never tried it on the bike. Now i just use the Wahoo with my Fenix.

      The run dynamics data is not worth the pain associated with using the Wahoo Fittness app.

  66. Arlene M

    Looks good. I often use a treadmill for running – does it need a footpod? If so can you recommend a Bluetooth footpod that will work with it? Does it have vibration alerts?

  67. Paul in Kirkland

    This is the first watch that has made me consider switching from the Vivoactive HR. It seems like it isn’t THAT far off from the Vivoactive, and that most/all of the shortcomings can be addressed in software updates (like sleep, which you mention). Is that a fair assessment?

    It’s certainly better looking, which isn’t a high bar.

  68. Cornelius Puiulet

    I really wanna buy a Suunto, but Suunto always manages to miss some feature that I find important, that Garmin always seems to nail. This time is the multi sensor pairing. I own a number of sensors, ant+ and Bluetooth. A couple of power meters, 5 hr transmitters, Tempe, foot pods, 4 speed cadence sensors. With my FR935, I pair ones and I’m done. Just grab a hr transmitters, jump on any one of my bikes with a power meter and I’m off. It would drive me crazy if I had to re pair a Power meter or another sensor every time I change bikes or hr transmitters. Come on Suunto, I really wanna buy your products. And now that Garmin’s products are Bluetooth and ANT+ compatible, looks like I’ll be sticking with the garmin camp. I pretty much think the fr935 is the perfect multisport watch for now.

  69. Sascha

    Can the Trainer get the distance from Stryd in (outdoor) running mode with GPS activated?

  70. Hi Ray,

    I’m interested in the navigation capabilities of this watch. From what I read in your review, this watch can receive tracks from movescount. What does the watch-screen look like when using navigation? And how does it give directions? Via audio, vibrations, on-screen?

    Thanks for the review!

    • Janne

      Would be also really interested seeing e.g. how routes are created and how it looks in the watch when navigating. This could be really useful tool in trail running or mountain biking.

  71. Pieter

    Just when I thought the Polar M430 might be a good next option, Suunto comes along with this model for only $50 more…?

    (Currently have both the M400 and A3S : ) )

    • Cogs

      I am with you – have a M400, and am contemplating an upgrade. Ray – help us: the M430 at $229, or the new Suunto at $279. I am primarily a runner (to the extent the multi-sport aspects are a helpful deciding factor).

    • It’s tough. The Polar unit has detailed structured workouts (and creation thereof), which the Suunto unit lacks. Meanwhile, the Suunto unit is better if you happen to get into triathlon. And I think overall it’s a bit more well-rounded. Plus, I think it looks better.

      Just my two cents…

    • runnershigh

      which watch (M430 vs. Suunto Spartan Trainer WHR) snugs better on a small wirst? Easier fit would be helpfull if OHR should work as good as possible in my opinion…

    • Daid

      Hi Ray, do you expect structured workouts to be delivered at some point? The lack of this functionality is the only thing preventing me from pre-ordering today as really like the look of this.

  72. This watch is a very interesting product. Obviously in gold because gold is the color for winners in sports.
    I was thinking about buying the Suunto Spartan Wrist HR Gold but it is kind of big and heavy compared to my Polar M400. Hence, I need to go check out this new model when it is available in stores.

  73. Crispin E.

    Excellent thorough review as ever Ray. You mention near the start of the menus video that there’s an unboxing video too. Unless I’m missing something really obvious (my wife says it wouldn’t be the first time) I can’t find an unbixing video here or on your YouTube channel. Is this yet to follow? Also couldn’t help noticing in the menus video that there appears to be a brighter spot on the screen at around the 10 o’clock position. This is similar to the bright spot on the Fenix 3 at the 5 o’clock position; but Garmin appears to have sorted things out on the Fenix 5 so there’s no discernible bright spot. I would have thought Suunto had refined this too, so is it really as obvious as it looks in the video?

    • Sorry, yeah, unboxing video coming up. Got delayed on the editing of it with the giveaway extravaganza and all.

      I don’t really notice it personally while using it – so the video may be making things worse. The lighting in the DCR Cave is generally a nightmare – so most things end up looking worse than they are.

    • Crispin E.

      Thanks for confirming my Wife’s not right about my ‘mansight’ missing things (at least on this occasion); I’ll keep an eye on your YouTube channel.

  74. Mads Sørensen

    Does the Spartan Trainer have the ability to do workout planning like for the Ambit 3? So creating the workout with intervals etc in the app and download to the watch.

    • Dark Passenger

      You do that at your own risk…

      In Ambit 3 there was a bug for which any structured workout created on MC is “added” to the stopwatch – i.e first a lap is snapped on the stopwatch AND THEN on the structured workpout, thereby increasing the lenght of each interval. I have seen a customized workout with many laps to last over a minute longer than the intended lenght because of this…. i’d like to think they have fixed this poor programming in the Spartan…

  75. Dark Passenger

    Yet again three buttons on the wrong side of the watch…. & I assume the Lap time is still on the other side….

    Dont they get any feedback that the Lap & Start/Stop need to be on the same (right) side, or it is very awkard to snap a lap, and even better if they are the only two buttons (a-la Garmin)…. SMH

  76. RG

    Thank you for the great review (as usual) and for the great news: a triathlon watch at this price will make buying one possible for many of us, and perhaps it will push down the price of other equivalent watches, hopefully.

  77. Ben

    How does the accuracy on the GPS altimeter look?

    Thanks Ray!

  78. Jeff D

    Ray,

    Another great review. I was thinking about buying a Polar M430, but this new Suunto Spartan has made me have second thoughts. Is there much difference in size between the two watches? I have small wrists so that is an important factor for me. Is there any possibility of uploading any photos of The Girl wearing each watch (a lot to ask I know, especially with the Peanut and Peanut #2 on the way!)

    Jeff

    • Robin

      Hey Ray, thanks for all your great reviews! I, too, am currently in the market for a new watch as an upgrade from my m400 and have been thinking about the m430 but now I find myself flirting with the suunto spartan trainer… Any chances we can get a size comparison of these products on The Girl’s wrist? Thanks! :)

  79. Manfred Schuette

    What about the size of the data fields? When I have three columns, do they have the same size? I have an Ambit 3 and only the column in the middle is big enough for me to read without my glasses. The other two ones are much smaller. No chance to read them while running.

    • Runa

      Agreed. Got lots of friends in their late 40’s who like my Spartan Wrist HR but wouldn’t buy it cause they can’t read the tiny menus. Eg. battery percentage. With all that glorious real estate, why doesn’t Suunto just increase the font size?????

    • I’ll put together a little mini-gallery tomorrow when it’s light out of the 1-7 data page field sizes.

  80. John

    Hey Ray. Thanks for the review. I have a bunch of questions I don’t think these questions have been asked yet. What is the screen diameter? Is it a 1.2″ viewing screen? All of the photos of the screen look dull to me. Did the resolution look acceptable to you? I assume you can change it to a white screen rather than the dark screen that is in all of the photos (right?). The bands are not swappable, correct? The bands look rigid. Were they relatively comfortable? Last question: can you see the whole notification, or just the first line of it? Thanks!

  81. roy

    Hi Ray!
    in the comparisontool, whwn selecting watches for triathlon, this watch doesnt light up. Maybe something to adjust?

    • roy

      And please make available for Clever Training UK

    • Fixed for tri selection. I always forget to tag the watches correctly in my database. :-/

      As for CT UK, it’s coming on Aug 30th (or maybe it’s 31st). Either way, it’s a Suunto restriction on listings, they aren’t permitted to list till then.

      (Side note: This is always a weird thing that mostly European companies do around listing new products. It never makes any sense from a business standpoint – because you lose the ability to capture a customer when they first hear about it and are initially excited about. 2-3 weeks later? And you can guarantee at least some people have lost interest/forgot. Most US companies have figured this out and have product listings/copy available to all shippable regions on Day 0 of a product launch. It’s funny hearing the stories of CT and others trying to explain to mostly Euro vendors why this is so important. Anyway…)

    • Tim Shears

      You are so right.

      Having read your review I would have immediately pressed a ‘buy one now’ button if I could have had it delivered the next day.

      As I couldn’t, I have done further research and may well buy something else instead, and from somewhere else.

    Hi,

    thanks for this review. Perfect as always.
    I am thinking about ordering it, but a question remains for me. I have an ambit peak and a stryd power meter. When I get to training with power according to some books it was clear that it was almost impossible because the interval trainer in the android movescount app only allows 100w wide zones….whereas I needed more precise trimming.
    Do you know if the spartan trainer allows more precise configurations for power ?
    I tried to ask Suunto team if they plan to update this specific part for the android movescount, but no answer.

    Hi,this is a very interesting review(because i am new one and i don’t know a lot about this kind of technology). So I am trying to find the best sport watch for me (this would be my first watch of this type) but i can’t find some details i want in order to take my final decision.First of all i would like to know if this watch supports silent alarm clock feature(I mean to wake me up with only vibrations and not to use any sound). Also, is there any way to change the watch face (apart from the faces that the watch has inside)?Finally do you think that this watch is better than the forerunner 630 or not(because i can’t spent more than 300$)?Thank you in advance and thank you for your time.

    • roy

      Well, the FR630 is no multisportswatch, primarely for running. And for running it is easily one of the best out there. You get a shitload of information. But it has no inbuild hr-sensor. So its very hard to compare these two watches.

    • TasosLep

      Do you mean that FR630 has a huge difference in running from the new Suunto? I’ll specially use ( just ) the step counter(but i would like be much accurate) and not a lot the running feature because i want the watch for swim also,and i see that FR630 doesn’t support it.Which one do you think is better to buy(or any alternative watch)?Maybe have to wait for the new Forerunners?Thank you very much for your previous answer.

  84. Robert

    Ok. So it’s this or the Polar 430. If I’m just using it for running, is there a reason to go with the Suunto Trainer anyway?

  85. Richard

    I use Linux with my Ambit 2s, and I dowlnoad my runs from the watch using OpenAmbit. Here:
    link to openambit.org
    I guess the Spartan Trainer is using a different protocol, but it may be similar in which case the developers of Openambit may eventually support the Trainer.
    Another option is to use Virtualbox, which should support all watches.

    Hi Ray,

    In the comparison table, point “ACTS AS DAILY ACTIVITY MONITOR (STEPS, ETC…)” says “YES” for Suunto Sport Trainer and “steps only” for Suunto Spartan Sport Wrist HR. Is it confirmed? It would be kinda silly to have Sleep tracking for “budget” watch, and lack of it for the full featured Spartan Sport Wrist HR. Waiting for my SSSWHR shipping by the end of August I’m kind of worried now.

  87. Ivan Dobski

    I’m sure I’ve just missed it but does it have an indoor running mode? I’m pretty much down to this or the Vivoactive HR for running inc indoor, basic indoor swimming and mtbing (no power or cadence sensors etc) – any strong reason why I should go for one over the other?

  88. Ruben

    I don’t know if this is common, but I started getting very choppy HR readings from my Fēnix 5 unit which I managed to resolve by *loosening* the strap a little. I was seeing by flat lines on the graph with no real relation to sprints etc, just like the watch had stalled and would just keep logging the last known HR until getting a new one.

    So, I loosened the strap by one notch and tried to keep the sensor more accurately over the “fleshiest” bit of my wrist and that seemed to fix it.

  89. Marco

    Hey Ray,
    thank you so much for the incredible amount of info and details.

    Just a quick question:
    have you had the change to test the altimeter at all?
    do you have any info/data on the accuracy of it, and maybe on how fast is the response time for it?
    I saw that it doesn’t have the jumpmaster option marked, but could you use it just as an altimeter while falling from a “perfectly good airplane”?

    Thank you so much in advance.

    Br,
    Marco

  90. alexei

    ray, on triathlon mode, can it be changed? lets say we have an indoor triathlon, pool swimming, etc…. can we change that ?

  91. Dennis

    Hi ray
    Do you know if there will be a trainer with more outdoor functions like a barometer maybe with no optic hr
    Something like the ambit 3 peak
    Thanks

  92. Roy Brooksbank

    fantastic review as always Ray, i was looking to buy a garmin forerunner 235 as could not find anything else around that price point until now.After years of putting up with disappointing Garmin cycle computers i was reluctant to send any more money there way.

  93. Hi

    Have you done any tests against the Fenix 5 series from a wrist HR perspective? Interested to hear your thoughts if you have DC

    • Almost all of my testing has been with the FR935 on the opposite wrist. That unit uses the same exact sensor as the Fenix 5. The only difference is depending on which version of Fenix 5 you have, and your body type and such, you may see better performance with less heavy watches. So since the FR935 is plastic it’s lighter than the Fenix 5 editions, and as such *may* result in better performance depending on your person.

      All that said – within my Fenix 5 review I dive into boatloads of data on it more generally compared to other sensors.

  94. Kim

    I am considering to retire my Forerunner 225 for a Spartan Trainer, but I have one question. Do the Suunto Movescount app offer altitude correction on the GPS data, similar to Garmin Connect an many other apps? It’s a very useful feature for non-barometric watches.

  95. Aydin

    Hi Ray,

    Thanks for the review. I have a question wrt “create/follow custom workouts”; your custom chart reads no for this feature, what is it exactly you mean with “create/follow custom workouts”? Do you mean that this is not possible to do on the unit? We can still do it through app though, right?

    All of a sudden Suunto became very very interesting again. I see this unit as a very good upgrade to ambit 3 which they should have done almost 2 years ago. It even has vibration now!! :)

    Thanks for your answers!

  96. Rob Robinson

    Hello. I’m having to send my Ambit2 Peak (which I love) back to Suunto for repair (condensation under glass). If they can’t fix it- then they’ll most likely issue me some sort of partial credit (because it’s out of warranty) to purchase a new one. The Spartan Ultra is way over-priced so I was going to get an Ambit3 Peak or Ambit3 Vertical- but this new Spartan Trainer Steel looks appealing.
    1. I notice the Spartan Trainer does not have watch-based (without a foot pod) Running Cadence. I find this hard to believe as both the Ambit3 models have it. I know I’m in a small minority but I constantly use Running Cadence every time I run. Any chance the specs on Suunto’s site is incorrect regarding this or will they be adding watch-based cadence later as a SW update to the Spartan Trainer?
    2. Taking wrist-based HR (they don’t work too well on me. Straps work better)- and altimeter & weather functions out of the equation- which watch is a better replacement option for me? Ambit3 Peak (approx $270 new on-line), Ambit3 Vertical (approx $240 new on-line) or Spartan Trainer Steel ($329)? I’m mainly a runner with some triathlons- but mostly running and as my day-to-day all-purpose watch. I don’t mind paying a little more for the Spartan Trainer Steel if it’s a better choice than the Peak or Vertical. I’m unsure! The Running Cadence thing is kind of a big thing for me. Thanks! Rob

    • 1) It has running cadence, the specs on their site are incorrect.
      2) It’d probably also depend on if you find value in the Suunto apps that exist today, since you can’t get those on the Spartan series.

    • Rob Robinson

      Thanks for the reply! I’m glad the Spartan Trainer has Running Cadence. I haven’t really used the Ambit apps much even though I think it’s such a great thing.
      Also- what does the Spartan Sport w/ optical HR really have that the Spartan Trainer does not? To justify the price difference?
      Looks like I’m either going to get the Ambit3 Vertical or Spartan Trainer Steel. Can’t decide which one!

  97. TheRunningDaddy

    Hi Ray/All

    Let me ask again ;)

    In the comparison table, point “ACTS AS DAILY ACTIVITY MONITOR (STEPS, ETC…)” says “YES” for Suunto Sport Trainer and “steps only” for Suunto Spartan Sport Wrist HR. Is it confirmed? Do you Ray/anyone have info whether there will be Sleep tracking for original Spartan Sport Wrist HR???

    That would be silly if there wasn’t Sleep tracking implemented in more expensive equipment than Trainer, and I’m asking myself whether Ray made mistake in the table or is it just wierd Suunto decision

    regards
    TRD

    • Sleep tracking will roll-out for the Trainer unit on/about Aug 30th (it’s a firmware update technically, and one I don’t have, so it’s possible it could roll out at launch, or it could roll out days/etc later).

      All other Spartan units will receive it “about a month later” according to Suunto, so likely late September. I simply hadn’t updated/tweaked the other database entry.

    • TheRunningDaddy

      Hi Ray!

      Thanks for the reply. Now I will sleep well ;)

      Cheers

    • tfk

      ask Gerald Zhang S, he might have access to it (I don’t either)
      I think the aug firmware update is supposed to be ‘notable’…could be wrong

    • It has been released today. But I haven’t seen the changelog and I did not have time to toy around with it. But the sleep tracking is there (pic attached)

    • tfk

      yes I have sleep tracking now as well. it is motion based and just gives a basic summary really including average HR (Source: suunto). it will be rolled out to the Spartan and ultra (planned October). the sleep fucitonality is planned to be developed further
      there’s also a DND mode and a better battery indicator

      of interest to me: “At the same time, we are bringing performance enhancements improving pairing and connectivity”. so that looks good but I am not sure what it actually means…I have the firmware and cant see any new pairing functionality – although behind the scenes, for example, two channels from stryd could now be allowed -TBC

    • Regarding pairing/connectivity, it’s referring to the ability to connect more than one sensor of a given type, as well as to solve the dual-pedal issue. There’s no specific date yet, though I get the feeling it’s likely ‘fall’.

    • tfk

      nope. stryd can still only connect once to one sensor type.

    • The menu feels snappier. Previous version felt with a lot of lag everywhere. Not as “fast” as the Spartan Sport or Ultra, but there’s an improvement.

      Regarding connectivity, I haven’t had much time with it (I’m in a hurry right now… kids party in 30′), but I haven’t seen any changes in sensors. Only one sensor as always.

  98. roy

    Curious at how Garmin will react or if they react with the prize of their 735xt…
    Also curious about if there is difference in accuracy between the optic hr from the Spartan trainer and the 735xt.

    • Garmin will typically experiment with lower permanent prices in the form of temporary sales. I think $349 is a fair price for the FR735XT. It does after all have more features (a lot) than the Suunto Spartan Trainer, plus the app store and all sorts of things (true 24×7 HR, etc…).

      My bet is we’ll see them toy with a lower price over the course of the fall, and then eventually make it permanent. But, I’ve got no actual information that they will. Just a hunch.

  99. Thomas

    Hi DC,
    can you lock the buttons to avoid accidental clicks during a workout or inactivity? That feature isn’t in the Ultra series yet but hoping it is in this one.
    Thanks

  100. Andras Beck

    Hi All!

    Does anybody know if this one supports workouts via either Movescount website or app?

    Using Trainingpeaks atm, and I’d like to be able to plan and use the workouts I have to do (like I can currently with my Garmin Edge 510).

    Regards,
    Andras

    • tfk

      no to both.
      it’s on the roadmap but quite a few turns away from the current position.
      there are simple intervals on the device

  101. Jorge

    Hi !!

    Many Thanks to Ray for this review, What a exceptional guy !!, he help thounsand of people around the world !!

    To anybody :

    As a MTB guy , for me is very important Altitude, there is a display in the Ultra and Sport watches with your altitude, and a graph that show what’s going next in terms of altitude ( pre loaded before)

    Does anybody knows if this new model have the same display?

    Many Thanks

    Jorge from Peru

  102. Kunal

    On Suunto’s website, they mention that the SSTrainer has
    “Interval guidance with running pace/heart rate/distance – on watch”

    Would you happen to know if this is like, messages (about what to execute next) showing up during interval training and pace/heart-rate limits which if not met, the watch buzzes/beeps?

    This is mentioned on the SSTrainer product page > Specifications > Sport Expertise > Running.

    • It’s purely distance/time targets though. It just happens to show those other stats. I think I’ve got a photo above of what it looks like mid-run. If not I’ll dig one up from my camera.

  103. Alistair Wood

    Hi DC, do you have any more info on the battery life as suunto seem to say it only has 10hrs in sport mode?

  104. torte

    Hi DCR, thanks for the great review.
    As alreay asked by others, can you say something about the display quality? Do you need to have an eagle like eyesight to read the data in relation to the number of fields configered? How about outdoor use in sunlight?

    Second, I would also join the crowed asking concerning heart rate transmission support to other units.

    • It’s certainly a smaller display – but no more than other small watches out there. No issues viewing it (though, I do have good eyesight). No issues at all in outdoor sunlight.

      Unfortunately there isn’t HR re-transmission like you see on Garmin units or the latest Polar ones.

  105. Scotty

    Hey DC – great article again! I used your reviews to get my Spartan Sport HR last month… which brings me onto my question of, Have Suunto just undercut all Spartan Sport HR users (like me) as it looks like the Trainer does everything the SportHR does apart from a touch screen?
    I believe i’m still within my time to send the watch back so I could trade it back for the trainer? Although the sportHR looks much better!

  106. Ariete

    Hi Ray thanks for the review. Product is Made in China (assembled in China to be more correct) not Finland this time? I may have missed this in the review.

    • Correct. They started doing that with some of their other units a year or two ago.

      Hasn’t really made much of a difference. It’s not about where it’s made, it’s about how the company oversees it. After all, nobody says that the iPhone has poor manufacturing because it’s made in China. Whereas other companies can outsource to all sorts of places and have poor manufacturing due to lack of quality oversight.

  107. Janne

    Thanks Ray for the review. Based on your review, I had enough information to believe that this watch is best choice for me, so I made a pre-order.

  108. Alice

    Is this good for someone who hikes a lot and wants to improve the workout at the gym or would you recommend another model?

  109. Pete

    As ever a great review. I was decided to upgrade my Ambit2S to a Garmin Fenix5 or 935 just because they seemed more functional (and I use a Garmin 850 for my bike) and the Spartan seemed like a mess from your review. Now this comes along and hits a home run with the only thing I really see lacking is ANT+, but since I use a TACX Bushido that should not be an issue. I think this is a common dilemma, especially with lots of us using 2 platforms – Movescount and Garmin. Since I’m a rower first and foremost I am always hoping that one of these giants would appeal to that sport but never seems to happen. Other than cost – is there anything that should sway me one way or the other??

    • Rupert

      I also upgraded from an (excellent) Ambit2S to the Spartan series and after a fair bit of fiddling, managed to get all of the Tacx Genius data onto the watch. I use the CABLE as a bridge, but the watches connection to the CABLE between exercises is erratic (never drops during a workout), so you usually need to be re-paired the watch to the power pod each time in order for it to be connected to both power and bike pods. Not really a problem as you can see whether the little pairing icons are green before you start the exercise.
      Pic shows all the data being collected (power/average power/cadence/HR/speed/distance/time (just a coincidence that the last two are the same)
      Spartan Trainer uses the same software so it should work the same

  110. Pamela

    How does this compare to the Nixon Mission?

  111. maltloaf

    Hi and thank you for the great write-up again. I have based many of my purchases on your reviews. I’m looking for something to go multi sport as an upgrade from a Garmin 235 as I have recently started doing Duathlons. My question is can you set up a multisport duathlon activity ? As in Run, bike, run as a single activity ? Everything mentioned is geared towards Triathlon. I was all set to buy a Garmin 735XT or Fenix but this has thrown a spanner in the works as it looks like great value.

  112. RolandH

    Hi,

    anybody could tell me if the GPS continues when you pause your current activity ? 8 hours at 1-second GPS interval is already a bit short for those long cycling days and when it even contiues (and consuming battery power) when sitting 1/2 hour at your lunch when the activity is paused then it get’s even shorter.

    That’s something I really appreciate on the Garmin Edge 520, it even switches off completely during a pause and continues when you start riding – not wasting any battery power.

    thanks, Roland

  113. Susie

    This is an amazing review – I have one question though.
    I noticed a Ski Touring option on the sports – does the unit give you rate of ascent? That’s one of the most useful features of my old Suunto Vector!
    Thanks
