Suunto Ambit2 R In-Depth Review


Back in late January Suunto announced their Ambit2 R running-focused watch, which comes as a derivative of the Ambit2 line that was introduced last spring.  The 2R aimed to offer a lower price point than the higher end Ambit2 and 2S units, which were focused heavily on triathlon, ultra runners, and hiking/navigation.

But, is the lower price enough to compete with the glut of new GPS running units in the same price category? I’ve been using the unit for the last 6-8 weeks now on my runs, attempting to find the answer to that.

Because I want to be transparent about my reviews – Suunto sent me two final retail units to try out (white and black). Once I’m complete here, I’ll send these back to Finland and then go out and buy my own (to be able to support y’all in the comments section down the road). Simple as that. Sorta like hiking in wilderness trails – leave only footprints. If you find my review useful, you can use any of the Amazon or Clever Training links from this page to help support future reviews.

Lastly, at the end of the day keep in mind I’m just like any other regular triathlete out there. I write these reviews because I’m inherently a curious person with a technology background (my day job), and thus I try and be as complete as I can. But, if I’ve missed something or if you spot something that doesn’t quite jive – just let me know and I’ll be happy to get it all sorted out. Also, because the technology world constantly changes, I try and go back and update these reviews as new features and functionality are added – or if bugs are fixed.

So – with that intro, let’s get into things.



The Ambit2 R comes in two basic versions: With the heart rate strap, and without the heart rate strap.

Then, within that there are currently two color offers: black and white.  The black bundle as you’ll see in a bit means the band is slightly longer and made of a slightly different material.  Roughly speaking Suunto believes more women will go for the white bundle, and thus, the smaller band.

In any case, as far as unboxing goes – it’s the same contents for both units.


Inside, the box is actually pretty slim on random accessories.  It’s simply the watch, the USB charging cable, and a little packet of papers for the manual.  If you have the heart rate bundle, then it comes with the Suunto ANT strap.


Starting with that, we’ve got the heart rate strap.  This is the Suunto ANT version (not ANT+), which means it only works with Suunto devices.  If you have an ANT+ strap however, that will work just fine with the Suunto Ambit series, as ANT+ support was added to the whole series about 16 months ago.


Next, we’ve got the USB charging cable.  This cable plugs into any USB port on the planet, from your computer to your phone’s USB port.  It’s all the same for the purposes of this unit.


The clip simply attaches to the side of the unit.  It’s not the most secure clip in the world, but once attached on a desk it stays put.


Then we’ve got the quick start guide, offered in 98 languages.  Don’t worry, by the end of this review you’ll have all the concepts down.


With that, we’ve finally got the watches themselves:



The units are waterproofed to 50-meters (150ft in Americana units), which is why it doesn’t use a standard mini-USB port on the side of the watch, but rather uses the connector to the watch and a USB portion on your computer.


You’ll also notice that the unit has two little straps on the bands to ensure the longer strap doesn’t float around.  Personally, I’ve never much liked the dual-holder design, as it’s kinda cumbersome, but for those that do – it’s there for ya. I’ve been kinda tempted to simply just snip one off.  Perhaps someday…

Size and Weight Comparisons:


Above is the jail cell lineup of current generation running watches today on the market, with the ones most competitive to the Ambit2 R on the right hand side.  You’ll see the Ambit2 R sitting just to the right of the seam in the middle.  In this case, to the right of it is the Timex Run Trainer 2.0, then the TomTom Runner, followed by the Garmin FR620 and then FR220.

To the left of the seam is the Garmin Fenix2, then the Polar V800, followed by the Suunto Ambit 2, the Adidas Smart Run GPS, and then the Garmin FR910XT.  Everything to the left of the seam is $400+.  And with the exception of the blue FR620 on the right ($400), everything in that bracket is $200-$250.


Above, you can see that the Ambit2 R is reasonably slim, not quite as slim as the FR220/620, but still just fine.

Next, looking at the weights of the different units.  Since you’re likely fully capable of reading the grams displayed on the scale, I’ve just added the unit names below to the images.



As you can see above, a slight difference between the white and black units due to the strap length and material.

The 2S below weighs in the same as the black 2R, simply because…well…it’s the same physical watch.


Meanwhile, the Ambit2 (standard) weighs in quite a bit more.  And, if you were to look at the Sapphire Ambit2 version, that’s even heavier still.


Next, taking a closer look at the three Ambit2 units from left to right: Ambit2, Ambit 2 S, Ambit 2R


From the front of the units you’ll see the display itself is identical in all of them. The core difference is the bezel.  The 2R & 2S use a plastic bezel, whereas the Ambit2 uses a metal bezel.

Height wise you’ll see the 2S and 2R are identical, with only the Ambit2 being a bit chubbier.  Feature-wise the extra chub comes from the longer battery and the barometric altimeter.


If you look at the two variants of the 2R, they’re identical on the display except color.


Whereas the bands differ between the two.  The white version has a slightly smoother band compared to the black edition.   Additionally, the strap is longer on the black edition.


Finally, while you’ll see my arm and wrists throughout the review, here’s my wife’s arm/wrist with the units on her.  Her wrist size is 14cm (or 5.5 inches).  Here’s the white edition first:



Then the black edition:



Ok, with all that completed – let’s get onto using the thing!

Running (Outdoors):


Now that we’re ready to head outdoors it’s time to start the activity.  To do so, we’ll go ahead and tap Start and then select Exercise followed by selecting Running (or, any of our custom sports, which I’ll cover later).


Once you do this, it’ll go ahead and search for the heart rate strap (if you have it paired), as well as a footpod (again, if you’ve paired them).


Note that the 2R can connect to both Suunto ANT heart rate straps, as well as ANT+ heart rate straps (such as those from an older Garmin device).  As long as it has a little ANT+ logo on it, you’re good to go.  It won’t however connect to any Bluetooth Straps, nor any Polar straps (or Nike straps).

I’ve found on all the Ambit devices that initial pairing with ANT+ straps is often rather finicky (just the first time), and many readers comment on it as well.  Here’s the thing: Just keep retrying.  Stick the watch right up against the strap, and make the two do the romance dance.  And keep pushing retry.  Eventually, it does work.  And once you pair it once, it forever remembers it (sorta like having a baby I suppose).

In any case, heart rate strap behind us, it’s off to the satellite search.  By default the unit will pre-cache satellite data from Movescount when you plug it into your computer.  In doing so it will greatly speed up acquisition of satellites while standing outside.


I’ve been traveling a bunch and have been blown away by how fast it’s been.  Last week I flew to Mexico City, and then I walked outside and pressed to start finding satellites.  It found satellites for the first time in approximately 2 seconds.  It may have been 1.8, perhaps 2.2, I’m not entirely sure. I wasn’t exactly expecting it to take just two seconds.  Fastest satellite acquisition ever after such a long distance away from last turn-on (12hr flight from Europe).

Once you’ve got satellite, you can go ahead and press start to begin your run.  At this point the unit is now recording.  And as such, you’ll see that the timer is now incrementing, along with distance.


I’ll cover all the different fields you can show/configure later on in the review, but here’s a quick sampling of a few different fields while running.  Below, you can see my distance (2.17mi), my current pace (7:15/mile), and even my cadence (89).


In this view, I’ve tapped the ‘View’ button to switch the bottom field to show Average Pace (for the entire run), which is at 6:59/mile.  The remainder of the fields remained the same.


Whereas in this instance, I have heart rate shown along the bottom:


As you’re running you can show pace (or speed, if you want), as well as distance and time.  If you want to create a lap you can simply press the lap button, which then saves the information for later retrieval.

I use this when I’ve got a workout with different segments, which allows me to look at those segment’s lap times and distances easily.  You can see this below later on, within Movescount online:


On the display itself, you can both enable a backlight if needed by pressing the Light/Lock button, which will turn it on for the period you’ve defined.  For example, you can set it to automatically turn off after a specified number of seconds, or you can just have it stay on.  I personally prefer to just configure it to stay on for easy viewing during night runs.


You can also invert the display, so it’s white text on black background.  To do so, simply hold down the ‘View’ button for a few seconds and it’ll flip over.


When it comes time to pause a run, you can do that at any time by pressing the ‘stop’ button.  This is like pausing on your VCR…err…YouTube, and you can always resume the run without losing any data (for example, to stop and eat a crepe).


When you’re done for real, then you can press pause to pause it, and then press the back button once to access a menu asking if you’d like to stop the run and then save it.


Once that’s completed, the unit will then show you a handful of summary pages including totals (i.e distance/time), as well as paces and splits for laps.


You’ll also get your fastest mile and kilometer displayed as well:


Finally, you’ll get recovery time displayed.  This value is shown in hours, and is general guidance on how long you should wait till your next hard run.  I found this value was generally pretty close to what I was getting on Garmin devices that supported a similar metric.  In some cases, this value was slightly higher than theirs, but in the rough ballpark.


This value is also then shown on Movescount as well along with other similar metrics like your measured VO2Max and your Peak Training Effect (PTE)


Note however that some of these metrics depend on having the correct Maximum Heart Rate defined within the Movescount settings.  For example, below, my MHR is set at 178, which is far too low for me – it should be closer to about 188-190bpm, based on what I’ve seen.  As a result, some of my runs were showing a PTE too high (5.0), when they weren’t terribly hard runs.


The same goes for your activity class and resting heart rate, which can drive a number of calorie related metrics.

Running (Indoors):

Next, we’ll take a look at the Ambit2 R’s ability to track pace and distance indoors without the use of a footpod.  This is new to the Ambit2 R lineup, and will be back-ported to the Ambit2/2S units later this spring.  In order to enable this you’ll simply need to run outdoors first to calibrate the sensors.  The more you run at various paces, the more calibrated it is, and thus, the more successful it is.

The term of this feature is FusedSpeed, which actually does two things. First it aims to smooth out the usual GPS jumpiness in pace by matching that with your natural run cadence to determine your pace.  Basically, it blends the two together.  Then, in cases where GPS is sketchy or drops out entirely, it takes over to show pace/distance.  It’ll then resume back to primarily GPS based when GPS is good again (such as a tunnel).  This has worked flawlessly for me in some long tunnels around the city here (upwards of half a mile).

Having been running at all sorts of paces outdoors, I headed indoors to try it out on a treadmill.  I used a simple 10-minute increasing pace ladder to see how things would look.  Ideally, it’d match the paces I was going for.  Here’s the results:


Now, in order to correlate that I recorded the paces of the treadmill at each step (each for 1-minute).  I found that the paces were very close to reality.  It strayed more at the far end though (as I’ve seen elsewhere), but in the middle it did quite well.  And it wasn’t really till the last step that things got out of whack.  You can see however that like other units it struggled in that first minute or so.

And those little ‘dips’ you see at each step?  That’s because I used that particular hand to increase the treadmill speed, which ultimately impacts the pace.  Thus if you’re a treadmill-holder, this won’t capture data accurately (the ‘be honest’ person in me says that if you’re a treadmill holder you need to slow down the treadmill because you’re actually not getting the workout you need).

In the event you’d still like to use a footpod for pace, you can do so.  The unit will automatically calibrate the footpod based on the first 1-2KM of each run using GPS, and then the footpod will take-over as the pace and distance keeper for the remainder of that run.  This is a bit different than Garmin units, which allow you to generally decide whether GPS or footpod is used (or to just use footpod when GPS is unavailable, such as in a tunnel).

In addition to providing pace indoors, the unit also now provides cadence (both indoors and outdoors).  Here’s that same look at things from the cadence perspective.


In order to compare the cadence to something, I wore a footpod using another unit, and have that charted below.  Because Suunto and Garmin differ these days on how they display cadence, the below graph is simply ‘doubled’ over the above graph.  So if Suunto showed 90SPM, then Garmin would show 180SPM.

In comparing various points between the two, they trend quite well, and are within 1-2SPM across the board, minus a few exceptions.  Those exceptions would be cases where I did something with my hands, which impacted cadence (because it’s wrist based on the 2R).  You can see that above with that random 120SPM spike – which is invalid.


Thus, for most applications, the cadence is more than sufficient to not need getting an additional footpod.

Finally, of note is that the unit will use the heart rate strap to determine calories while indoors even if not running.  For example, I rode my bike on a trainer and just used the heart rate strap.  The unit was able to calculate my calorie burn despite the distance showing ‘zero’, and was also able to determine a relatively accurate recovery time for my activity.

The same is true if you’re weight lifting or doing yoga – it all applies as long as your personal body metric settings are set correctly on Movescount.

Altitude and Elevation:


I wanted to very briefly cover this, given it’s somewhat unique to this price range to see elevation/altitude displayed.

The Ambit2 R does allow you to display the current elevation of the device.  In the case of the 2S and 2R, it’s using GPS to do that, and not a barometric altimeter.  Generally speaking, barometric altimeters are more accurate than GPS altimeters, but in my testing I’ve continued to be fairly impressed with how well the Suunto GPS-based altimeter calculations have worked out, usually right on track with barometric altimeters.


You can add the altimeter (elevation) field onto any data page on any profile you want.  You can also show total ascent and total descent as well as vertical speed.

As I noted earlier, none of the other units in the sub-$250 price range show elevation on them, let alone ascent/descent and vertical speed.  So if you’re looking for that data, the 2R is definitely a contender here.

GPS Accuracy:


In line with completing multiple GPS unit reviews at once, I’m always looking at GPS accuracy.  It’s a tricky topic, because everyone on earth believes their current GPS is always the correct one.  Thus, any variation to that must be incorrect.  Further, there’s the incorrect assumption that simply measuring something in Google Maps is the all knowing truth.  When in reality, that rarely accounts for all the tiny variations that add up over the course of a run (see this post to understand more there).

For example, while a race may be measured perfectly as 13.1 miles, in reality, you as a participant will generally run between 13.2 and 13.5 miles, depending on how efficient you are.  If your GPS comes back and says you ran exactly 13.1 miles, then more than likely the course was short (or, your GPS was enabled for a mode that only updates rarely).

With that said, my job was somewhat easy in the case of the Ambit2 R, because it basically always agreed.  At least, agreed within the margin of error that’s common for consumer level GPS devices (up to 2.5%).  Below, are a random smattering of data points I’ve taken over the past 6-8 weeks:

Run A:
Fenix2: 18.36mi
Ambit2 R: 18.40mi

Run B:
Fenix2: 5.63mi
Ambit2 R: 5.79mi

Run C:
Fenix2: 7.50mi
Ambit2 R: 7.53mi

Run D:
Ambit2 R: 8.11mi
Garmin FR620: 8.03mi

Run E:
Fenix2: 17.53mi
Ambit2 R: 17.55mi
Garmin FR620: 17.42mi

Run F:
Ambit2 R: 17.59mi
Garmin FR620: 17.46mi

As you can see, they all vary slightly.  Conditions changed from route to route, with everything from trees and forests to tall buildings and half-mile long tunnels.



While Ambit2 R is specified as a running watch, it actually works just fine in other sports, such as cycling.  Part of that comes from the flexibility of the platform of the watch being able to change metrics.  Because all of the modes are defined online, by you, you can easily create your own cycling mode and then customize the display as you see fit.

For example, typically in cycling you’d use speed as a metric (either MPH or KPH), whereas in running you’d use pace.  So for your data fields you’d want to select speed-specific fields.


But fields such as distance and heart rate are the same across all sports, making them easy to add to your data pages and fields.

When it comes to mounting the unit, you can either place it on your wrist, or use cheap $9-10 bike mounts.  These are readily available on major sites, and Suunto sells one, as does other companies.  These little rubber blocks just wrap around your handlebars and then you wrap the watch around it.

Note that the Ambit2 R doesn’t connect to ANT+ speed or cadence sensors.  It ONLY connects to the ANT+ heart rate strap and ANT+ footpod.  And use of the ANT+ footpod while cycling gives you funky and often non-consistent data, usually about half the average value (if you’re lucky), but it tends to have a slight correlation with speed.  In short, it’s junk data.

But, the heart rate portion works just fine while cycling – so no problems there.

Day to Day Watch:


The Ambit2 R can easily be worn as a day to day watch with GPS off.  In this mode you’ll get approximately 15 days of battery life.

In this mode, you can configure a single alarm that can be setup to audibly beep such as for waking up in the morning.  The unit does not contain any vibration functionality however, so there will be no buzzing along with it.

Like most GPS watches on the market, the unit can automatically set its time via GPS, but it does not set the actual offset of hours.  Which, is kinda wonky.  Said differently, when I flew back this past week from Mexico, the time on the unit was incorrect, because I had to change the hours on the unit to display the current time zone.  So it’ll basically keep the minutes/seconds correct, but not the hours.

Alternatively, if you just plug it into your computer, it’ll match the computer’s time.


With Ambit’s history rooted firmly in the navigation and routing department, it comes as no surprise that’s a major selling feature of the Ambit2 R.  And in fact, I’d go as far as saying that’s the singular reason you’d buy this over competitive units.

So what options does it have?  The two primary options are the ability to navigate a course (route), and then navigate to a given waypoint (POI/Point of Interest).  Let’s start with POI’s.

POI’s are pre-defined points that you navigate directly to, as the crow would fly.  For example, if you saved a POI of your home, or other starting location – and then navigated to it, it would route you directly to that POI as the crow would fly.  It would not take into account roads, buildings, bridges, water, etc…

To navigate to a waypoint on the 2R, you’ll select Exercise > Run a POI.  Then, you’ll select the POI that you have pre-defined on Movescount online.


POI’s on the 2R must be predefined on the computer for this particular menu.  However, later on once in an activity you can both save the current point, as well as define a point based on a set of coordinates.

On Movescount, POI’s are defined using the Navigation area under a watch’s gear settings.  You’ll create POI’s and Waypoints separately, but be aware that waypoints defined within a route do appear to count against your total number of POI’s available.


To create a POI, you’re simply going to use a Google Map in either satellite or mapping mode and zoom/drag your way around until you find the spot you like, and then save it.  You can give it a few different categories (with various icons, like the forest/tree one below), and then a custom name.  Ensure the box is checked to transmit it to this particular watch.


Back on the watch once you’ve selected the POI, it’ll then go ahead and search for any ANT+ sensors you’ve previously setup (just like it would on a run).  Following that, it’ll search for GPS signal.  Once that’s done, you’ll be brought to any screens you’ve configured as part of the sport profile online.  For example, by default, here’s what the ‘Run a POI’ profile looks like:


You can customize these fields to anything you’d like.  So realistically, you could make any sport navigation-capable, or  you could just access the navigation menu and trigger them from any other sport.


In any event, the key field that you’ll be looking at is below, which shows you how far you are from the POI, as well as the direction to travel:


The direction is dictated by the magnetic compass within the unit, which you’ll calibrate by flipping the unit around a bunch (twirling, if you will):


The reason a magnetic compass is important is because it doesn’t require you to be moving.  Whereas a digital compass uses movement and the direction from a GPS to determine which way you’re facing.

Now that I’ve covered POI’s, we’ll step it up to Routes.  Routes are defined on Movescount, and can include multiple waypoints, as well as a general track between the waypoints.  You’ll use a map just like defining POI’s, except this time you can connect the dots.  Note there’s a few options along the bottom, specifically the one that in the below screenshot says “Follow roads walking”.


This option controls how the map will follow various routes, as opposed to just connecting the dots.  In general, I’d recommend it.  Note though that while doing this it chews up ‘points’ in the total allocated points.  You’ve got 10,000 points on the watch to work with (which are different than Waypoints/POI’s).  In this case, I had 5 waypoints added as well.  These are spots I’ve defined.  I can name these spots and give them fancy icons too.

Like the POI option, ensure you check the the ‘Use this route in watch’ option, otherwise, it won’t be transferred to the watch. That transferring, by the way, does require you to connect your watch via USB to the computer.  So definitely don’t forget to do that before you head outside to navigate (been there, done that).


Ok, so fast forwarding to outside, we’re back on the watch ready to do a route.  In this case, you’ll go ahead and select either from the main menu to ‘Run a Route’, or, from the quick settings menu to pull up the waypoints from a given route.

In our case, we’ll just go from the main menu:



With that, you’ll see a map of where we are going.  Now, this is again why it’s important to ensure there are defined waypoints, as otherwise it’ll navigate you directly to the final waypoint along the way (not so ideal).


As you near each point the unit will show the watch counting down, and then it’ll advance to the next waypoint, ultimately culminating in the finish line.


As noted earlier, by holding the ‘Next’ button down at any time during an activity (of any sort), you can then access the Navigate menu.  From this menu, you can: Navigate a Route, Navigate to a POI (waypoint), Save your current location, select ‘Find Back’, or ‘Track Back’

Track Back is the option to re-trace your route back home along the same route you went out.  This is ideal for out and backs, or other complex situations where you can’t just go line of sight back to the starting point.  It’s less ideal however if you’ve made loops or other routes where you might be much closer to the starting point at your current location than reverting back through the entire course.  For that, you’ll want to just use ‘Find Back’, which is a straight shot.

Overall, the POI/waypoint creation functionality on the Movescount site exceeds that of competitor Garmin’s from a usability standpoint.  This is because Garmin doesn’t actually offer such functionality on the site, but rather only via phone and some older desktop software.  On the flip-side, doing it via phone and transferring via Bluetooth Smart is incredibly quick and easy.

Looking at the routes functionality, both companies are fairly similar and use pretty similar options on the site.  So that’s less of a deciding factor.

Finally, within the navigation aspect, I again repeat that if navigation isn’t of interest to you, I’d really consider other watches.  If however, the navigation piece is of interest, then the 2R’s functionality is equal to that of what many watches offer at the $400+ price point.  And, given it’s the same root functionality as the higher-end Suunto Ambit units – there’s plenty of known stability there.

Suunto Apps Zone:

Suunto was the first major GPS watch company to introduce the idea of installing miniature ‘apps’ onto the watch.  And to date, nobody of of major significance in the industry has followed them.  The apps aren’t quite like you’d expect from an iPhone, but rather much more basic.  These apps are essentially performing a calculation and then displaying that as a data field.  Further, they can store those values to analyze later on Movescount.

Upon the release of the 2R, Suunto introduced a series of apps aimed at the 2R, to go along with the watch.  These apps aren’t loaded by default, but do appear in the suggested apps listing when you add apps to your watch.


Apps range the gamut from ones that count as a display field how many beers you can consume based on calories, to complex interval workouts.  Anyone can design an app, though, it does take some basic math or computer programming knowledge to understand how to do so.  Using them is possible for anyone with no such knowledge.


One of the ones introduced (seen above) is one by Suunto to implement interval functions into the watch.  This works by pre-defining a slew of apps based on different paces for the intervals.  You can then tweak the app to meet various requirements, such as the number of reps that you’d want to do.

In many ways, the sheer quantity of apps makes for tons of solutions to niche problems.  You can as a result make a data field for just about anything on earth, in the event that the fields aren’t natively available on the watch.  This is an area that really sets the Ambit apart from the field.  In the case of other companies, if a data field that you want isn’t there, the general answer is ‘too bad’.  Whereas here, you can either create it yourself, or beg (ask nicely) some other person in the community to do it for you.  That’s pretty awesome.


On the flipside however, it also means that Suunto has kinda gotten away with substituting apps for what really should be features and functionality within the watch itself.  And a perfect example of that is actually the interval option as seen earlier.

In this case, virtually every other watch on the market has a simple to use interval mode on the device itself that I can quickly define and start running.  Here, I have to go online, find the right pace app, save it to my account, then tweak it, then download it to my unit, and then run it.  And if I want to change the pace or warm-up? I’ve got to do that all over again.  It’s something that I’d barely want to do, let alone asking The Girl to do (and she has way more patience than I).

Which don’t get me wrong – I think the App Zone is awesome.  I’ve said that from the beginning.  But I think it should be beyond the base features of the watch.  It should allow developers to do kick-ass things (which they are), but it shouldn’t placate for basic functionality that other units have.

Data Fields, Pages, and Configuration:

The Ambit2 R has considerably more configuration and customization options than any of the other watches in this price range.  To start, we’ll look at the data pages.  Each sport profile you create on the watch can have its own data pages, and each page can have up to three pieces of data on it.  These different profiles can be named whatever you’d like, and categorized as any activity you’d like.


As you can see, you can tweak till your heart’s content on the data page layout.  Layouts also include apps.  So where you see it showing “10K time” above, that’s actually an app called “10K Time”.

Next, if we click on one of those data fields, I’m given a menu to choose the data fields.  They are categorized along the top, and then I can select the button next to the ones I want.


For the bottom fields I can actually choose many different data fields, and then use the ‘view’ button to switch between the same field along the bottom.  That’s why in the image two above this, you see a little (3) next to one of the fields, which indicates I’ve selected multiple data points.  For example, I could select ‘Time’ and ‘Pace’, but keep the same upper set of fields.

Here are the total set of data fields you can select today:

Speed: Speed (current), Average Speed, Pace (current), Lap Avg Speed, Lap Avg Pace
Distance/GPS: Distance (total), Lap Distance
Heart Rate: Heart Rate (current), Average Heart Rate, Peak Training Effect, Calories
Attitude: Altitude (current), Ascent, Descent, Vertical Speed
Time: Chrono, Day Time, Dual Time, Lap Number, Lap Time, Battery Charge
Cadence: Cadence (current)

This is in addition to any apps that you design/add.  So basically, you can generally speaking find a data field for any attribute on the planet from cupcake consumption to oxygen consumption.

Below each activity profile that you’ve created is the option to select the recording interval and the GPS accuracy (among other options).  This is really critical to understand.  The recording interval has virtually no impact on battery life, that’s more for storage.  It’s the GPS accuracy that impacts battery life.   There are three basic options, which align to the following:

– Best: 8hrs battery (1-second update rate)
– Good: 12hrs battery (5-second update rate)
– OK: 25hrs battery life (60-second update rate)

Then of course, there’s GPS off, which lasts a long-ass time.  For general conditions, you’ll want to leave it on the 8hr battery life option.  If however, you plan to go longer than that, switch it up to 12hrs first, and then as a last resort the ‘OK’ mode.  That OK mode isn’t that great because it only checks your GPS position once every minute.  In twisty conditions, a lot can change in a minute, and a lot gets cut-out.


It’s also in the above settings (again, for each custom profile you want to tweak), that you can enable features such as auto lap and auto pause, as well as which ANT+ or Suunto ANT sensors to use (heart rate strap or footpod).

Next, looking at additional settings on the the watch, you can change all sorts of display options through the ‘General Settings’ tab.  From how the buttons react, to how the backlight functions.


As I go down further I can specify how the different units are shown – such as kilometers or miles.  And the same goes for date and time aligned to different people’s preferences.  If I were to click the ‘Advanced’ option next to units, it essentially allows me to split out which way I want to see different metrics for height, weight, distance, and altitude.  For example, I could show distances in miles, but height in meters.


Last but not least on the configuration front I can setup my personal settings, which ultimately drives calorie burn calculations using heart rate data.


Movescount Online:

In order to get data online to Movescount, you’ll need to grab that USB charging cable and plug it into either a PC or Mac.  The unit contains no Bluetooth capability, so there’s no way to transfer it via your phone.  And, since I’ve received a number of questions on it, none of the Ambit lineup will transfer files via ANT+ (such as with the little Movescount Mini USB stick).  Only via USB cable.


Once that’s done, you’ll be using the Moveslink software uploader, which is a little device agent that hangs out and grabs files off your computer and uploads them to the Movescount site.  Every time you plug in your unit it’ll look for new files, upload them, and then look for any settings changes from online to push back down to your watch.


This is also the time when the watch gets it’s satellite pre-caching data downloaded to it, which speeds up initial satellite searches and lets them take only a second or two.

Once all that connectivity jazz is done, your completed activities will be up on Movescount ready for you to analyze.  Do note that if you’ve made any changes to the watch while it was plugged in, those usually won’t sync until you’ve unplugged and plugged it again.  So if you’ve added an app or the like, just unclip and reclip the watch to trigger it to download again.

Movescount continues to come a long way since it was introduced, slowly by surely adding in more and more functionality to the site.  Upon opening up Movescount and heading to the score you’ll be shown a look at your summary for the past 30 days:


Diving down into my most recent run, we’ll start from the top, which has summary information about it, and the ability to export it.  You’ll see all the top-line stats like average pace, total distance, and recovery time.  Note that these can all be shown in either metric (kilometers) or statute (miles) depending on your preferences.


As I scroll down the page, I’m given a map overview. I can zoom in, or change the map to satellite view if I’d like.


One pretty cool feature is that the coloring on the line is tied to the metrics I’ll talk about in the next section.  So above, it was tied to my heart rate.  Whereas below I’ve changed it to tied to elevation (altitude):


Those metrics are shown on a graph that I can enable/disable any of the different recorded items for this run.  In this case, I went ahead and selected heart rate.


But I can easily select other metrics and add them to the overlay, such as below, with pace.


Below that there’s a bar chart and curve of my paces.  Given this was a pretty steady run, there’s very little deviation there.  And further down on the page is my lap summary.  These are based on me having defined it to auto lap every mile.


Going back up to the top, you’re able to export the run in the file formats of XML, GPX, and XLSX.  While .GPX isn’t bad for uploading to some sites, and .XLSX isn’t bad for doing your own Excel-style analysis, it’d be much better if Suunto outputted into .FIT format, which is widely accepted and understood by every sport platform out there.  The challenge with the export formats today is that some sites struggle with the additional data recorded by the Ambit but not exported.  For example, if you export out the .GPX file, it doesn’t contain the lap data, so sites like Training Peaks can’t really do much with more advanced analytics.

Looking briefly at a few other features, the site includes a calendar of your activities that can be accessed from under the ‘My Moves’ section.


You can also add in activities from various training calendars that are community sourced within the site:


However, these plans don’t actually transmit workouts to the unit that can be run, but are rather guidance for you to browse online.  So think of it more like a paper plan, than a digital one to follow.  On the watch itself it’ll tell you what you need to do zone-wise for the day (in terms of time), but it doesn’t give you a specific workout to follow.  For example, from the home screen you’ll see text along the bottom that there’s a training day:


Then, if you tap the ‘Next’ button, it’ll show you what’s on tap for the day (which correlates with the 30-minutes on Tuesday you see in the screenshot just before the photo above).  But you can’t actually execute a workout from there. So it’s kinda more sticky-note than executable workout.


The platform includes many social sharing and following aspects, sorta like Facebook or Twitter.  You can follow users, and thus in turn, follow when they complete activities.  You can also look at other users’ activities (assuming they’ve allowed you to).  And you can make comments on other users’ activities (again, assuming they’ve allowed you to).

Lastly, one lesser known feature is that Suunto has been enabling various partner sites for direct import and upload.  This means that when you upload a workout to Suunto’s site by plugging in your watch, it’ll automatically go to a partner site.  Below, are some of those sites available today:


I went ahead and enabled connectivity to MapMyFitness, simply because that’s a service I use occasionally.  To do so, I just followed the links on this page and then under ‘Improve > Device Connect’ on the MapMyFitness site, I selected Suunto:


In doing so, it brought up a little notification of how it was going to transfer the data over (the last 30 days worth), and that it would then redirect you to the Movescount page for authorization, which it did, as seen below:


Within about 10 seconds, my workouts for the past month showed up:


Very cool stuff.  Hopefully we’ll continue to see the partnerships from Suunto’s side expand, especially as they are one of the first GPS device makers to support automatic upload from the device to 3rd party sites.

Bugs and Miscellaneous:


As I’ve been doing on all reviews over the past year or so, I’ve been including a section on bugs and/or issues that I’ve seen within my timeframe using the unit.  Do remember that  a ‘bug’ is different than ‘by design’.  For example, the lack of a feature is something I highlight within a given section is considered ‘by design’, whereas something not really working right is considered a bug. In the case of the Suunto Ambit 2R, such bugs fall into one of two categories: The device, and the platform (uploader/site).

Within the device itself, it’s been incredibly stable.  I’ve seen some oddities in some of the Suunto designed apps while using them, but it’s hard to understand what the cause of those issues was (aside from errors on the screens).  Thus, it may be a transient app item, or a watch item.  In cases where I wasn’t using apps, I saw zero firmware-level issues with the watch itself.

And to that end, that’s generally true of what I see of Suunto devices (hardware and firmware).  They really tend to hold up quite well.  And I generally think we see fairly equal hardware across the board from the major players (Garmin/Suunto/Polar), sure, you can always find a case of someone breaking something on hardware – but from what I can see, they’re fairly equal.  When I look at the software running the hardware, I think we see less buggy firmware from Suunto than others.  Some would argue however, that by implementing less features, they’re able to increase quality.  Whether or not that’s the appropriate tradeoff either company has to make, it appears to be the case.

On the website side, my day to day usage hasn’t brought me across any showstopper bugs that have prevented me from completing tasks.  I still do have a beef with the lack of proper export file formats for sport-related data from Movescount, but hopefully in time that’ll be resolved (at least, it sounds like that’s on the radar).

Product Comparison Chart:

I’ve added the Ambit2 R to the Product Comparison Tool, which means you can mix and match it against any other watch/unit that I’ve ever reviewed for feature comparisons.  Note that there are some features that are on the Ambit2 R at launch that will be added to the Ambit 2/2S down the road.  So in general, if it says ‘Yes’ within the Ambit2 R table, but no in the Ambit 2/2S, it’ll be there eventually in the 2/2S.  But I didn’t want to set them as ‘yes’ now, because then folks buying the device between now and April/May might think the unit has that functionality.

For now, I just added the Ambit 2/2S/2R into the below chart.  However, you can easily make your own change with any device you want here at this link.

Which Watch?


So, you’ve made it this far, but can’t quite decide which watch makes the most sense for you?  Well, here’s a couple of brief thoughts summarizing what I’ve sprinkled throughout the post.

The Suunto2 R is really aimed at people who both run and hike (and want navigation capabilities).  It’s as simple as that.  Well, sorta.  See, the 2R isn’t really the most advanced running watch on the market in terms of connectivity.  It lacks things like Bluetooth Smart support for uploading via your phone, and it doesn’t have the in-box flexibility of many other units when it comes to either intervals or workout direction.  So in that respect, if you’re spending your time mostly on asphalt, it might not be the right choice for you.

On the flip side, if you’re in the hiking and navigating crowd, that does some running, or potentially some other activities like cycling – this is definitely a better choice.  Especially compared to the higher end options costing more than $100 more (like a full Suunto Ambit or Garmin Fenix series watch).  Further, unlike the competitive Garmin FR220, the unit can easily be turned into a cycling watch.  Whereas the FR220 can display in ‘speed’, but doesn’t recognize cycling workouts, which in turn by default hoses up various metrics when uploaded (like PR’s).  And for clarity, I confirmed with Garmin last week that the FR220 will not be getting a cycling mode (as the FR620 is getting).

Is it for the triathlete?  No.  It doesn’t track swims at all (except if you put it in your swim cap), and there’s no multisport mode, which means that you can’t easily switch from sport to sport.  Now that said, you could definitely make it work in a pinch.  You’d create three sports (swim/bike/run), and then simple end the activity and then start a new one.  With a bit of practice you’re only talking a few seconds lost doing it.  Especially since the satellite pickup is often only 1-3 seconds if in the same place.  Plus, the full-on legit waterproofing means the water isn’t a water hazard.

Finally, one item to consider (as pointed out by a reader in the comments), is that for a limited time the Fenix1 is now available for $299, just $50 more than the Ambit 2R.  So that changes the dynamic quite a bit – especially for folks wanting the higher end features previously only found in the $400 watches.  Still, by the same token, it’s easy to play the “just $50 more” game, and before you know it you find yourself with a $400 GPS watch.



The Suunto2 R aims to bring down the cost barrier of entry for Suunto’s line of GPS watches.  And to that end, it definitely succeeds, simply because it’s cheaper.  They kept the two core navigational functions (waypoints/routes) as well as the ability to load apps and the ability to load custom sport profiles.  Two major benefits not seen on other units in this price range, and ones that offer massive customization potential – in many ways far beyond what is even offered at the top-end price range on competitive units.

On the flip side, the lack of Bluetooth connectivity to the phone puts it behind many of the other units in this price range such as the TomTom and Garmin watches.  This means that any configuration and uploading must take place at a desktop computer.  Further, some of the functionality such as intervals and custom workouts should really be in-box at this price point (no, the default interval timer is not sufficient as-is).  Suunto is somewhat in a tough spot here in that leveraging an older hardware platform puts them a bit behind the curve in the one market (mid-range) that’s actually seeing the most new entrants with the most flexibility in features.

On the online front, Suunto has made good strides there, and their ability to implement integration with major partners like MapMyFitness to have instant workload uploading is a huge step forward.  Hopefully we’ll see other major players get connected like Strava or Training Peaks, which would greatly appeal to the more serious athlete.

Ultimately, I’ve covered my recommendations in the ‘Which Watch?’ section directly above on who this device is targeted at.  If you fall into the right target group, it can be a sweet watch at a price below the higher end units but with just the right amount of flexibility and customization.

Found this review useful? Or just want a good deal? Here’s how:

Hopefully you found this review useful. At the end of the day, I’m an athlete just like you looking for the most detail possible on a new purchase – so my review is written from the standpoint of how I used the device. The reviews generally take a lot of hours to put together, so it’s a fair bit of work (and labor of love). As you probably noticed by looking below, I also take time to answer all the questions posted in the comments – and there’s quite a bit of detail in there as well.

I’ve partnered with Clever Training to offer all DC Rainmaker readers exclusive benefits on all products purchased. You can read more about the benefits of this partnership here. You can pickup the Ambit2 R or accessories through Clever Training using the link below. By doing so, you not only support the site (and all the work I do here) – but you also get to enjoy the significant partnership benefits that are just for DC Rainmaker readers. And, since this item is more than $75, you get free US shipping as well.

Suunto Ambit2 R base unit – white or black (simply select color from dropdown)
Suunto Ambit2 R with the heart rate strap (simply select color from dropdown)

Additionally, you can also use Amazon to purchase the Ambit2 R or accessories (though, no discount). Or, anything else you pickup on Amazon helps support the site as well (socks, laundry detergent, cowbells). If you’re outside the US, I’ve got links to all of the major individual country Amazon stores on the sidebar towards the top.

As you’ve seen throughout the review there are numerous compatible accessories for the unit. I’ve consolidated them all into the below chart, with additional information (full posts) available on some of the accessories to the far right. Also, everything here is verified by me – so if it’s on the list, you’ll know it’ll work. And as you can see, I mix and match accessories based on compatibility – so if a compatible accessory is available at a lower price below, you can grab that instead.

    Hi –
    Does anyone know if there is a way to load a gpx file onto the watch as a route instead of having to manually click through the waypoints on movescount? I’m doing an 80k self-navigated race in a couple weeks and was hoping the Ambit2 R could help me in this regard.


  2. umberto

    thank For Your reports.
    I have a Suunto Ambit 2r. Exporting route in xlsx I can see something strange on recorded date.
    I set repcording 1sec. And gps accuracy at max (8 hours autonomy).
    So in the file there is a row For each Second but in column ‘distance’ i can see Values up only every 3/4 rows.
    I have some older runs where distance up every Second For the first time and then after 20/30min start with gps distance every 2 sec, then 3sec , 4.
    It is normal? GPS accuracy it is really 1sec?

    • rickNP

      I don’t know if you ever got an answer, Umberto, but I too, see this. I set everything to 1 sec and “Best” within MovesCount, but when I import my track into mygpsfiles it tells me I only have 616 track points in a 45 minute run. I wonder if maybe I need to reboot or something. I’ll keep testing.

  3. Zed

    Hi Ray, great review (as always I would say). As I am in the market right now to upgrade from my Suunto M5 to most likely Ambit 2 R, I was wondering if I’m good to go with my current heart rate strap of M5 (Suunto dual), as you are mentioning above heart rate straps ANT or ANT + ?

    • Yes, Suunto ANT is fine with the 2R.

      That said, just a word to the wise – the 2R is actually more expensive than the 2S right now (which is $219US). And, the 2S has everything the 2R does, and a crapton more. 😉

  4. Cormac

    Thanks for the great review Ray.
    Have my 2R since last Friday from my local store. Love it so far, the ability to configure multiple sports such as circuits, cycling, various running types (road, track, trail, indoor) is great.
    I’m not a triathlete so don’t need a multisport device, though it is useful to have the flexibility of other sports if doing some cross training.
    One quick question – I noticed when charging it for the first time that the watch enters a power save mode after 10 minutes static, which obviously is the case when charging at a desk from a power socket. This interrupted the charging so I had to keep moving it to stop it going to sleep.
    It didn’t seem to be the case when plugged in later to the laptop at home.
    This could have been fixed in a firmware release but I haven’t seen any mention of it here or elsewhere.
    I’m only just under 50% so won’t get to test it out again for a few days.

    Saying that, the battery % display on the normal watch screen is a great idea. It gives a good indication of how much power you have left & you get to know roughly how much power you need for a given activity.
    Build quality seems really sturdy compared to other watches I’ve seen and handled and it doesn’t look out of place in the office like a lot of others would.

  5. Tyler

    Thanks for the review! I decided to buy the Ambit2 R and I was hoping you could answer a few questions I have. I have always run with a Garmin and like the audible alert feature when you hit each mile. Can this watch do that?
    Also, does autolap need to be selected to get data for each mile (if it is set to a mile)? I would like to run a race and be able to go online and see my data for each mile. When I selected autolap it seemed to start the time and everything all over again during the run. I don’t want it to do that.
    Finally, when I retrieve the run data on Moveslink it still has it in Km even though I set it to imperial. On the “moves” screen it tells me my total distance in km. How can I change that?


    • 1) Yes, it has auto lap functionality. Yes, you’ll need to enable it ahead of time, or, just manually press the lap button each mile.

      2) On Movescount, you’ll want to also change your display settings to imperial as well.

  6. Thang

    I own an unknown cheap Schwinn gps watch ( probably a rebadge or soleus because I can use the same software) and it take quite a long time to get the signal. So I jumped on the Ambit2 R with a special deal and I am very impressed with the build quality, the flexibility of configuring the screen and the ability to lock gps signal within a few seconds. Today, I ran 4 miles with both watches and I think the Schwinn does better job than the Ambit2 R. First, the Armbit2 R reported 0.05 mile shorter (4.05miles vs 4.10 miles). Strava shows the same distance from both watches: 4.10miles. I ran on the same narrow path/trail on the way back and the plotted lines are much more closer with data from the Schwinn watch than the ones from the Suunto. I wouldn’t care and wouldn’t know how bad is the Armbit2R. I am casual runner who just run to stay fit so it doesn’t matter much but knowing my old cheap GPS watch outperforms my newer one really ruins my excitement.

    • Thang

      After going back and forth between the two data, I would say the Armbit2 R did not record good data during the first 4 minutes where there are many tall trees and building. I will run on open trail and compare again them again.
      Any suggestion?

    • Honestly, a difference of only .05mi on 4.05 miles is roughly 1%, which is within range of GPS units that typically get within 2%.

      Given it’s only one run, I’d look to do additional runs. Do ensure you have good satellite coverage before starting. I’ll often wait another 10-15 seconds after it finds coverage just to get a nice solid lock.

  7. Grey Darrah

    I’m having the hardest time trying to create a custom cycling mode. I guess the screens have changed on Movescount from the ones you show here. All I’m wanting is a watch screen that displays current speed, distance and average speed. MPH would be preferred, but I think you can only use KPH. It seems like that would be an app that someone has already created, but I can’t seem to find it or figure out how to create it. Any help you might offer would be appreciated.

    • No need for an app, you can do that via the standard display customization using the Movescount site. Just add a new data page and then click left/right to three rows. Then for each row choose one of the three data fields you noted above.


    • Grey Darrah

      Thanks so much for the reply, and I’m sorry for being such an idiot, but I cannot figure out how to add a new data page on the movescount site. Is there any way you could you tell me more specifically where I create this? I’m a “Garmin guy” and I’m trying to set this up for my wife…we’re new to Suunto.

    • Jaimy

      It should be rather easy like Ray described but let me be a bit more specific
      (you can always check any of the Suunto videos (YouTube channel) or Suunto Ambit2 R manual if Ray’s review or my description do not seem to work for you).
      This is generally how you create your own dataset on a display:
      On the movescount website go to: Gear -> Suunto Ambit2 R
      Under the Customization tab you should see a number of pre set sport modes.
      Select your sport mode (in your case you probably have a Cycling mode) and click on the red Edit button. You should be able to see different kinds of (pre set) displays.
      You have a maximum of 8 displays per sportmode to configure.
      Just select an empty watch (with no data shown) and click on ”add display”.
      From there on you can use the black right/left arrows to switch display types and
      use the blue arrows to choose what to show in this row.
      In your case:
      current speed = Speed -> Speed
      distance = Distance/GPS -> Distance
      average speed = Speed -> Average speed

      You can clear other displays by clicking the red closing button/x.

      My pace shows min/km and my speed shows km/h. I’m not sure if this is customizable through any of the settings.

      Good luck

    • Grey Darrah

      Thanks a million! That was so easy (I love step by step instructions) and worked perfectly.

    Great. Movescount website has been down since at least December 21st. Did a run on the 22nd: unable to sync. Promised it would be up 24th (today). So did a run today, website still down, unable to sync. Now they are promising it will be up by the 26th. I think this is unacceptable, especially given the facts that most settings on the watch need to be changed from the website and not on the watch.

    It is about time Suunto gave us the same as Tomtom: ability to upload directly to Strava, Endomondo and the lot (there is Strava connectivity, but you are required to upload to Movescount first after which it will sync to Strava, so that is not working now either)

    Hi, great review!
    what do you think is best, polar m400 or ambit2 R, from a runner perspective?

  10. Thang

    Well, my Suunto ambit2R failed after 10 runs. The watch stopped recording in the middle of the run and now I could not sync with the computer. I went to the exercise menu and it seems like the memory was corrupted. I tried to update the firmware to refresh the watch and now it is bricked. :(. I will go back to my old watch then. Hopefully Suunto will fix it.

    Hi Ray,
    Do you know if there are any issues with the Wahoo Tickr Run pairing with an Ambit2 R? I spent about 35 minutes the other day trying to get the two together, but to no avail. The Ambit will pair with the HR strap it came with, but not with either the Wahoo or an older (much older) Timex HR strap. Thanks for providing such a comprehensive review site.

    • Daniel

      Hi Thang,
      Did you manage to pair the tickr?
      Does the recovery time , epoc and so on work fine with the tickr?

    I am a beginner runner. I do mostly trail running and some hiking. So far, I have been using Runkeeper on my phone to track my runs. Here in Canada at the moment, I can have the Suunto Ambit2 R with the HR strap for 224.99 and Garmin Forerunner 910xt without the HR strap for 249.99. I am torn between the two. Since I mostly run in the mountains, I want a reliable altimeter. The 910xt as a real altimeter and the A2 R uses the GPS. I would prefer the A2 R since the 910xt is so old, but the 910xt for 249.99 is so cheap…

    Any thoughts ?

    Hi, this is quite honestly the best review for the Suunto Ambit 2R in the WWW.
    I purchased mine in December after taking up running more seriously.

    Every running book says you have to cross train. It’s pretty much forced upon. Just recently I joined a gym and started doing laps in their pool. Can I use my Ambit 2R just to keep track of lap and times while swimming indoors? As of now I just look at my watch and keep track of the seconds after every lap. I just want an option that can do this automatically and save the data.

    Thank you

    • Unfortunately not – only the 2S or 2 (full edition), or the Ambit 3 non-R variants.

      That said, you can certainly hit the lap button to just keep track of time – but it won’t give distance/etc…

    Hello Ray,
    This is an amazing website, especially for a new runner like me who has no idea how to compare sports watches, so thank you! I am a male who has particularly small wrists; they’re only 1cm bigger than your wife’s, so your pictures of the watches on her wrists and comments about how bulky they feel are very useful for me. Seeing that the white version of the 2R has a smaller strap, I’m more drawn to it than the black one. However, on Suunto’s website, it describes the white 2R as being designed especially for women. Similarly, Garmin categorise their FR10/15 watches as being either for men and women. I was wondering if there is anything other than the styling that makes a watch gender specific?
    Best wishes,

  15. emac

    No, there is nothing gender specific about the Ambit 2R. I am a woman; I have had one for 19 months now, I love it.

    In the personal info where it figures out your metabolism, though, even on this one it asks you to say male or female. It uses the same displays and has the same software as the other ones. The white strap IS smaller; the white strap is also softer and way more comfortable than the others. But it does not say “for women” anywhere o the watch and that strap is the only difference…

    • James

      Thanks very much for the info, emac, that really helps!

    Hi Ray,
    I read from the other forum the ambit’s silicone strap/band tend to broke less in a year even in normal use, is this true??
    Appreciate your kind of feedback as im looking for this kind of watch…
    Thanks in advance…

    • I haven’t heard of other complaints of that. It may be a handful of people, but nothing that I’ve seen folks complain about here.

    • Lanz

      Thanks for your fdback ray
      Fyi i’m from malaysia & i got this -ve fdback regardg ambit silicone strap from suunto official website (review/fdback) & from their sales/marketing team too, i wonder why…hmmmm
      Btw thanks again ray, really appreciated your view…

    • Sqf1

      I’ve had the Ambit since new. I’ve replaced the band every year because it breaks every winter. I tried both versions with similar results. I’ve paid more for straps $70 each than I did for the watch. I love the watch other than that.

      How do you take off the watch? Don’t pull and bend the straps. Just push the bucket as you want to tighten the straps and turn your arm so that the tongue just drops out.

  17. Peter Hart

    Was going to post this on Ambit 1 but it seems to have fallen into disuse and I guess there is the same issue with Ambit2 and 3 etc.
    Had the Ambit for a couple of years and really like and use it all the time. Lately the watch started to fail to hold charge eg dropped about 50% in 12 hours just in timekeeping mode, looks like it needs a replacement battry for which there is a replacement kit ( a normal CR 2032 battery). But the watch has to be returned to a service depot for the replacement and as there are none in Australia, the watch has to go to Hong Kong!! Just to replace a common battery. Apart from the time factor, I wonder how much this is going to cost me? Surely it cannot be that difficult to disassemble the watch to put in a new battery but have searched everywhere on line without success.

    Has anyone ever tried to do this, or does anyone know if there are any instructions,videos etc

  18. Hossein Rezaeehagh

    my wife is gonna but a Suunto Ambit 3 sport online
    but she has got some doubt about the size
    isn’t it a little big for a female wrist?
    maybe it’s fine for a male but for a female i think it’s huge like every one will notice in a bad way?
    what do you say?



  19. Lyes

    Hi Ray
    Thank you soo much for this extremely detailed review, I just bought one and I love it :)
    just one thing you may want to add in the elevation / altitude section :
    the watch always records altitude (through GPS), but it only calculates ascent / descent when you use GPS accuracy at BEST (1 s). It does NOT calculate the ascent / descent in the other modes (5s and 60s).
    But still, you can use an app to display this data anyway :)
    So for the hikers and ski-touring guys who don’t use the GPS with the max accuracy (so the battery lasts long enough), be careful :p

    thanks again for you amazing work :)

    I am a triathlete and am trying to decide between the Ambit2 and Ambit 2 R….. (I am not interested in stroke counts). For the difference in price is there a recommendation on one over the other? Another other Suunto’s I should consider? (my price point is ~ $300; preferably less)

    • CMV

      Hi Rob,
      as a triathlete you should be looking at the Ambit 2S, as it includes openwater swimming and a multisport mode.
      If you don’t care about using your training watch as a daily watch, you should also consider the Garmin 910XT… it’s just $250 at Clevertraining right now, and it remains one of the best triathlon watches on the market. And if you don’t care about pool swim metrics, you could even save another 90 bucks and go with the 310XT.

    • I’d agree with CMW – I’d go with the 2S over the 2R anyday. And, unless you’re looking to do a ton of hiking in the mountains where precise altitude while hiking is of concern, i’d skip on the Ambit2 (non-S).

      Finally, as CMW noted, through the end of the week there’s also that FR910XT deal, which if you’re paying $30 more for, is probably worth it. (Details here: link to dcrainmaker.com)


  21. May I charge this watch (and any other that has a USB charger) with a wall charger? E.g. the one that came with my smartphone.

  22. Peter Hart

    Can you explain how the compass works. You say it is magnetic and therefore I presume North is Magnetic North rather than True North. How is this accomplished in a digital watch and how does the watch take account of different magnetic variations across the world. I would really like to have this confirmed to use the watch for orienteering etc

  23. ponost

    I am a relatively new runner (aiming for a full-marathon at year’s end) and have been looking for a watch to wear everyday as well as to help with training. Recently I purchased (without much research) an Ambit2R at a local store on sale for $180, primarily because it has Dual Time, a feature I need for work. Somewhat overwhelmed and still figuring out which of the features will help with training, I came across your impressive article/review. Based on all the info provided, this watch may indeed be more than what I actually need. I am wondering should I keep it or do you or does anyone have a recommendation for another watch in this price range or less (Tom Tom Runner/Cardio, Garmin FR15, PolarM400 etc were mentioned) which has a multi time zone/watch feature? Thank you!

    • For a pure runner, I’d definitely look at the M400, but none of the others you mentioned have dual time zones (really only the Garmin Fenix series has it).

  24. rob

    Hi! Love the site and wished I had read it in more detail prior to making my purchase. I recently bought the Ambit 2R and am considering returning it. Overall, I’m not really impressed with the user features compared to my old Garmin 205.

    Just a quick question and hoping someone can help:

    1. I did my first run the other day and the overall pace differed from what loaded to strava- it varied by 4 seconds. I posted this question on the suunto support board and all I received was that they use different algorithms. So which pace is correct? I did use the manual pause a couple times if that matters. Does Suunto base the overall pace on paused time too? I never had this variance when uploading data from my old Garmin.

    • rob

      Nevermind this question, I just noticed that there was a variance on the distance that caused the paces to be off.

  25. Ferenc Zsigri

    I have an ambit2 and created a multisport mode for triathlon. Outdoor swimming/running(depo1)/cycling/running(depo2)/running. It works fine but when I check movescount.com it doesn’t give an option to view the pace, only speed. Have you experienced he same issue? thanks

  26. Dominick


    I noticed when comparing gps watches that according to the table the Ambit 2R doesn’t have a virtual racing partner, but it actually does; its called Ghost Runner and it’s available as an App. You have to select the pace of the ghost runner and install the ghost runner at a specific pace as a screen to your watch.

  27. Sergej

    Hi DC,

    could you test please if you Ambit2R working well with Scosche RHTYTHM+.

    Cheers. Sergej

  28. There’s so many comments, so I apologize if this is a duplicate.
    I have the 2R – done deal. But I mountain bike. I’ve already figured out how to add it as an activity, and I’ve added apps that are purposed in MTB-related data tracking (speed, slope, total uphill distance, etc) …. But what’s the best way to utilize the 2R for navigation purposes? Can I record a route by riding it, and then replay it next time, so my GPS takes me on the same route? If so, how would I do that? I feel as though using a map to define the route is good for roads, but not trails which wouldn’t be defined on the map.

    These Ambit reviews are great, by the way. It’s like the owner’s manual I never got!

  29. Kelsey

    Awesome review! Quick question — I know you commented on the display features. Are you able to display Total Distance, Time, and Mile Pace @ the same time? Trying to decide between this watch and the Garmin Forerunner 610. Thank you!

  30. mario d

    i just got a gpulse heart rate belt hrm-ble-300 and i tried to connect my suunto ambit 2 with it. i didn´t succeed. so is there someone who could help me with my problem?

    • morey

      you’ve gotta hold the watch right next to the HR monitor. so that the watch case is actually touching the HR strap. then keep trying. you may have to do it 15 times, but once it’s paired, it will be good.

    • One minor itty-bitty problem:

      You’ve got a Bluetooth Smart strap, which isn’t compatible with the Suunto Ambit 2/2S/2-Anything. The Ambit2 uses ANT+, whereas the Ambit3 uses Bluetooth Smart.


  31. Kam

    Is this waterproof? You mentioned putting it in your swim cap. Could it take my heart rate while I’m deep water running?

    • lyes

      Hi Kam
      yes it is waterproof but it doesn’t take heart rate under water. Only Ambit3 series can do that.
