Suunto Announces Slew of Spartan Firmware Updates, New Custom Watch Builder


Just under a month ago, when Suunto announced the new barometric altimeter equipped Suunto Spartan Sport Wrist HR Baro (yes, that’s really the name), it also hinted at some upcoming firmware updates.  Some of these were casually referenced within the release of the Baro, while others were just left to your imagination. Now though, Suunto has unwrapped the full list of what’s new in a packed firmware update that starts rolling out today to all Suunto Spartan Units.

But in addition to all that, you can now build your own Suunto watch using various parts/bands.  It’s sorta like a build a bear workshop, except with the bear being an expensive GPS watch.  Also, it’s not soft and cuddly.

Building your own Suunto:

Suunto’s now rolled the ability for you to build out your own watch, selecting everything from the buttons to the strap.  All of which they’ll happily do up in whatever colors you want.  Here’s how it works.  First, you start by picking a compatible product:


For the fun of it, I selected the Spartan Ultra.  After all, go big or go home!  Once you do so, you’re brought to a page with a ton of options.  You’ll note on the left side are all the things you can customize, and the right side are the color/material options for that specific component.  I started off with tweaking the buttons and making them copper.


Then I went back to the glass and selected Sapphire glass for the display, and copper for the upper bezel.  That set me back another $70.


Then I changed the strap to white.  At present, the strap options are somewhat limited to just being colors.  That’ll change soon I’m told.  I also changed the case (basically the backing) to white too, just cause.  None of these pieces cost anything extra.


Then I changed the buckle (on/of the strap) to copper, to match everything else.  That was also free.


In case you’re wondering at this point, here’s the simplified version of the things that currently cost money to add/change.  Ones without a price are free, as are the various color changes for the bands/case.


Next was an important decision, but obviously, I changed the charging cable to match the case.  Can’t have any sort of fashion incident here.  Regrettably they don’t have things like orange charging cables, else I’d have gone back and made an orange watch.


They do however have the hideously ugly lime green heart rate strap you can add to it.  Which I did, for $50.


And then the holy balls moment, I can customize the back of the unit:


Ok, that can be hard to see, let me zoom in:


Suunto isn’t actually the first company to allow customization of the back of the unit.  Quarq did so with their Qollector, and indeed when I ordered one later on I customized it for free

Once all that’s said and done it shows me a purchase page and says a delivery time of 5-10 days.


In other words: Dude, you’re getting’ a Dell Suunto!


In seriousness, this is neat stuff, and is definitely going to be appealing for those that want a specific look on their unit and don’t mind waiting a few extra days for it.  Do note however that at the very bottom it says ‘No returns’, but that the normal warranty applies.

The Firmware Update:

Here’s the quick listing of what ya need to know, with some of my comments after each one, start off with some new data fields that you can add.

New Data fields: Interval average pace, vertical speed, run counter (skiing and snowboarding), estimated time to POI, estimated time to route end, % of max HR, Sunrise and Sunset

Most of the above are pretty standard on other watches, though, what’s really interesting is the ‘run counter’ item.  As noted there, that’s for skiing and snowboarding.  So yup, your Spartan will now count skiing runs (and probably could also be used to count downhill mountain biking runs as well).   Which, is a good time to talk about skiing…

New skiing/snowboarding focused data fields:

These include downhill distance, grade, speed in both current run and total in day variants. And in summary mode: Total run count, total downhill distance, total downhill descent, longest run distance, average sped and max speed, and total downhill duration.


These new fields are available for any of the snowy related sport fields: Alpine skiing, snowboarding, and telemark skiing.

The thinking here is much like we saw Garmin roll out a while back with their ski mode, which figures out when you’re descending and when you’re going up a chairlift.  It’s something I use a ton when I’m skiing, as it’s generally surprisingly dependable and handy.  It’s a bit early in the ski season to get some testing in (except for my brother, who I saw was hiking this weekend to the tops of ski areas to get in some early turns), but it’s definitely something I’ll do once I find snow and operating chairlifts.

Extended Sleep Tracking: Added sleep summary, 7 days sleep history, 7 days sleep HR average (for optical HR units)

We saw Suunto wander into the sleep realm a bit earlier this year with some firmware updates, but the functionality was fairly limited.  In many ways, it’s still kinda limited compared to most activity trackers, but this hits the core requirements for what most people are looking at (the last week’s worth).

Note that this data is still kept only on the watch, and isn’t enumerated anywhere yet online or via the app.  Hopefully, we’ll see that soon.  And of course, also note that the heart rate tracking is only for the optical-HR enabled models.

Navigation Updates: A bunch of new notifications

Suunto has added a smattering of new waypoint and point of interest (POI) focused changes.  These are primarily around navigating to a waypoint/POI, and specifically include:

– Waypoint and POI approach notification in route navigation (based on distance/proximity)

– Estimated time of arrival (ETA) or en route (ETE) added to POI navigation (in POI view)

– Notification showing ETE to next waypoint or POI on route has been added to route navigation

All of which will make it easier to know when you’ve reached your POI, as well as to determine how long or hopelessly lost you are in search of your POI.

New Watch Face: Shows moon phases, sunrise/sunset, and battery %

Here ya go, this is what it looks like:

I’m still hoping we’ll see Suunto add the ability to do some basic picture-focused watch faces, whereby I can take a picture from my camera roll and make it a watch face.  This would seem to play well into their hands of having a higher quality screen.

New Alarms and Timers: Sunrise/Sunset alarms, as well as Storm Alarm and Countdown Timer

These fall into the camp of bringing things back from the Ambit series, all of which were present previously either natively or with apps on that platform (since Spartan doesn’t have apps).  Note that the storm alarm is only available on units with a barometric altimeter (Spartan Ultra, Spartan Sport Baro).  Whereas the Sunrise/Sunset alarms and countdown timer are for all units.

New Languages: Turkish is available on all models, Thai on region-specific models, and notifications can now be shown in Hebrew.

Regrettably, I speak none of these languages, thus, I have no further items to add here on this one.

And a huge pile of bug fixes and tweaks:

Finally, a large bundle of bug fixes and performance improvements.  I’m just going to copy and paste this big list here, because that’s probably the most valuable way to do it:

  • HR belt connection reliability: addressing instances of HR belt losing connection and not re-connecting during activity
  • Now see power with Stryd also when paired as a foot POD
  • Ascent/descent calculation fixes
  • Bug fix for when GPS fix is lost while in ‘Good’ mode, but reconnected with ‘Best’ mode. Now returns to ‘Good’ mode as it should.
  • Watch usability enhancements: additional options in shortcut menus
  • Following software update, settings and sleep data are saved
  • Do not disturb mode enhancements
  • Failing sync scenarios fixed
  • Navigation usability improvements
  • Localization fixes
  • Notification reliability improvements
  • POD auto calibration can be disabled now in POD settings
  • Stability improvements

Phew, got all that?  Good.

I do want to call out this one specifically “power with Stryd also when paired as a foot POD”

This is a biggie in some circles, as previously in the Ambit series you could do this, but that functionality was lost in the Spartan series.  Now it’s back, which makes things a little bit cleaner when running with Stryd and whereby you also have another power meter on your bike.  That’s because until now you had to choose one or the other.  So if you were doing an Ironman race, you actually couldn’t get power data on both the run and the bike, you had to decide which one was more valuable.

Okey doke – all-in a pretty solid update from the company.  Certainly many of the software updates are more catch-up to what they had previously, but still, they’re appreciated and ultimately help to make the Suunto Spartan series more competitive.

I do think the customization thing is a good example of thinking outside the box.  We’ve seen Suunto mostly ‘follow’ for the last few years in terms of industry competitiveness.  Whereas this is really a good example of them doing something nobody else has done with respect to the major fitness players, and doing a pretty darn cool job of it.

With that – thanks for reading!

  1. Rob

    Does suuto have a watch suitable for swim and running and biking and sleep plus be able to store and play music with or without bluetooth? Thanks

  2. Sam de Bruyne

    I was pretty excited when i got the pupop update watch!
    In addition to your review:
    The new outdoor screen also displays a timeline when the sun is up and the transitions to dusk-sundown. It also shows where the sun is at that time of the day. Finally an “outdoorwatch” by suunto…

  3. Marcus

    Tried to update my brand new Suunto Spartan Sport Wrist HR Baro this morning, but during the sync something happened and my computer (Macbook Pro) lost the connection to the watch and now my watch is bricked.

    Absolutely nothing happens, tried all resets and different usb ports on my computer with no luck.

  4. Finn

    Is there somewhere, to compere these new watches, with Suunto Ambit Peak?

    • Tyler

      Yes on the Suunto website. You can compare up to 3 watches at the same time. The main feature difference is you can create custom workouts on the Peak and you can’t do that on the Spartan Series yet

  5. Robert Black

    I know the English and Americans have different way of pronouncing words, when there spelled the same, but it’s the first time I’ve seen route written as an American would say it :)

  6. Martin

    nothing for Spartan Trainer?

  7. John

    Thanks for the excellent overview of this firmware update. Some great features and fixes that they’ve put together.

    For Suunto, if you listen on here, I’d really like to see recovery estimates improved. They’re entirely worthless, despite an update over the past year. That, or an insight into what your definition of recovery is. I had a Polar v800 before and it would always have this nailed; 2 hour MTB race, Polar 48 hr, Suunto 120 hr.

    Sensor pools are needed as well. I have a gravel bike and a road bike, each with a power meter, it would be nice not to have to pair the sensor each time.

  8. Stoffel

    Still no custom workouts like on the ambit? :(

    • Andrew

      I hope Suunto realize how needed this is. Especially in conjunction with the now improved Stryd support. If they want to do something Garmin can’t running power structured workouts are it. There’s not a massive amount of people who will want it but certainly though. I’m ready to upgrade my 920 and if Suunto had this I’d order today.

    • Tyler

      I know, that’s the feature I’m waiting on before purchasing a new Suunto

  9. TUAL


    Les Spartan ont elles une fonction ‘Virtual Partner’

    Merci pour votre réponse

  10. Helm

    Great update! But after connecting with Stryd as a footpod, I unfortunately get no power displayed. Anyone else with this problem?

  11. Edwin Aerts

    Hello Ray

    I have an Ambit 3 Peak on which I installed a ‘grade’ app, showing hill incline for mountainbike/cycling.
    I consider to purchase a Spartan Trainer HR or Sport Baro HR. Is it correct that I cannot install apps on these watches, thus no grade features for cycling even with a barometric altimeter (Sport Baro)?
    You mentioned the grade field of the ski mode, does this work in other sport modes? Or is there another way to obtain this feature?
    Thanks for clarification.

    Kind regards

  12. Shmulik

    Great review.
    Any word about when the capability of adding custom app will be available on spartan?

  13. Andrew Kuhn

    I had Suunto Ambits 1 & 3 then switched over to a Garmin Fenix 3, and now Garmin Fenix Chronos. The one thing I loved with Sunnto (which is the only thing I hate with the Garmin) is the ability to organize and configure the data fields and activity paged on Movescount. Does Garmin have this capability somewhere that I am missing?

  14. Alex

    Ray, do you know if/when the Suunto Spartan Sport Wrist HR Baro will be able to be customized as well?


  15. Jordi

    I’m stoked about finally supporting the Stryd as a foot pod with pace, cadence and power. It’s going to make intervals in the city so accurate and convenient! Anybody has tried wether it’s best to disable gps footpod calibration?

    Besides that, the new watch face is very nice too. Big update this time.

  16. Paul D

    Hey DCR,

    Thanks for the post. Two updates:
    – The outdoor watch face also shows you day/night/twilight hours after you let the GPS run (eg, fire up navigation). When you took your photo it doesn’t look like the GPS had run yet.
    – Last time I check, the Ambit doesn’t show power when the Stryd Summit is connected as a foot pod – only pace/distance/cadence. You might be thinking of the older Stryd Pioneer which would display HR when paired as an HR pod but also display power from the power pod profile? The Ambit3 supported this in Dec. ’15 and the Spartan at launch.

  17. Gareth Fudge

    Has anyone else found that their watch has stuck on 1.9 firmware??

  18. pepe

    Has anyone noticed that after the update, the laps summary, after a run, has gone, and is only available online at movescount.com?
    I’ve checked this on my watch Spartan trainer, and on my wife’s watch Spartan sport WRH.

    • BartW

      For runs/swims done before the watch was updated this is indeed true.
      The moves on the watch are erased and only the basic info is send back to the watch.
      I didn’t look at the move i made after the update but on those moves the laps should be present.

  19. Ben

    Hi Ray,

    That’s a great update, especially the Stryd integration. One thing though: Stryd has apparently a great barometric altimeter built in. The SS trainer and the SS sport (WHR or not) lacks of barometric altimeter. One great improvement would be to use the barometric altimeter data from the Stryd (I believe it is available through bluetooth connection ?).

    Do you see them implement such awesome intégration ?

  20. Luka

    Hi DC!
    I’m looking to switch from my two years old fenix3 to something new and Suunto Spartan Sport WHR cought my eye.
    I would like to know was there any (significant) updates since your last review?

    • They’ve added a bunch of software features primarily. Though not too many since this post back in September. On their site they list the differences in the ‘Spartan Getting Stronger’ mini-site.

    • Jens

      Any thoughts on the 2.0.42 update? Would be very interesting to know if things have improved since the SSU is €310 at summer sale now. (minus HR belt)
