Polar Grit X Review – covering Grit X Pro, Grit X Pro Titan

Polar Grit X Review incorporating Grit X Pro Titan

Despite the wholly new name, this Polar Grit X Review finds an effective, new addition to Polar’s mid- to high-end GPS sports watches – the VANTAGE series. With only a few subtle exceptions, there is no need for existing Polar Vantage owners to move to the Grit X for their sports usage.

Model Superseded By: Polar Grit X2 Pro Review

Polar Grit X Review SpecificationsInterestingly; a few new, focussed features and slightly reduced pricing on the new Polar Grit X are taking the Vantage series into a brand new market segment for Polar, namely ‘Outdoor Enthusiasts’, which cover MTB, Trail Runners and, perhaps to a lesser extent, hikers. Are they offering the right people the right product? Let’s see…

Polar Grit X Review – What’s NEW?

There are several notable changes and additions but let’s start with what has been removed from the Vantage V as that’s a MUCH SHORTER list

What’s been removed from Vantage V?

All that has been taken from the Polar Vantage V is the Recovery Pro and Orthostatic Test. Also missing is the custom strap of the Vantage V. That’s it…kinda.

What You Still Get

Polar Grit X Review Specifications
Cardio Load appears after about 5 days of workouts

The full low-down on the existing Grit X/Vantage common features are here in the highly-detailed Polar Vantage Bible/Review. You haven’t got an hour spare to read that so here is the summary with links to detailed discussions of each feature should you wish to learn more

  • 8/10 Extensive, customisable sports profiles and a very good but not exhaustive range of training metrics which cover all major sports including swimming
  • 9/10 Excellent structured training support covering training plans and customisable workouts, all of which can be executed flexibly on your watch and supported by in-exercise functions such as laps, autolaps and audible+vibration alerts
  • 9/10 Training Load Pro is a super-cool feature too which is perhaps subtly more useful than Garmin’s equivalent but which, in any case, is a great way to track and guide your progress over the weeks.
  • 9/10 Sleep Stages Plus – in my experience, this is a VERY GOOD HRV-enabled sleep tracking platform that tallies reasonably well with my perceptions of my own sleep patterns and quality. I like the overall implementation though there is some room for improvement as sometimes too much complexity is shown on the watch.
  • Sleep Stages Plus results then calculate your Nightly Recharge  or ‘readiness’ score for the day ahead
  • 9/10 Adaptive training with Fitspark. Fitspark bases its recommendations, in part, on Nightly Recharge. It is an AWESOME feature which tells you exactly what kind of training you need to do as well as suggesting alternatives that even include guided strength and supportive workouts. It really is good BUT suits athletes completing only 5 hours/week of training (max, approx).
  • 8/10 Naturally, you get many “lesser features” such as all the relaxation stuff (Serene), steps, inactivity alerts, smartphone notifications etc.
  • 7/10 The low-powered GPS chip is still from Sony and you still have the onboard barometric altimeter (VV) plus a new, improved optical HR sensor. There is no SpO2/blood oxygen sensor which is no big deal.
  • 9/10 Polar Flow planning and analysis platform
  • 8/10 Strava Live Segments – works well, especially on longer segments, but limited for cycling by the small screen size.



New Specs, New Features

Comparing to the lower Vantage M model, you get EVERYTHING that the Vantage M offers plus Polar’s own running power, plus STRAVA Live segments, barometric altimeter plus basic route guidance. Don’t forget you now get AUDIBLE alerts which the Vantage M does not have.

Then you get all these totally new goodies on the Polar Grit X which neither the Vantage M/V has.

  • 100m water resistance (up from WR50) and a MIL-STD-810G durable construction
  • Power-save features give up to 100hours of usage by turning down GPS recording or the screen display period and completely turning off oHR. For almost all of us the 40 hours, GPS+oHR will be more than sufficient.
  • Standard 22mm watch strap compatibility (Vantage M has this)
  • New buttons – I liked the aesthetic of the Vantage V buttons but I’ll be the first to admit the Grit X buttons work better and work better with gloves.
  • A weight change to 64g (66g Vantage V, 59g Vantage V Titan, 45g Vantage M)
  • Modified Prime Hardware (optical HR) and algorithms to improve the handling of ambient light and motion artefacts (Source: Polar)
  • Compass – there is a new magnetic compass sensor and a compass display that’s only available during exercise.

Oh yes. These too 😉 These are the new features appearing on a Polar watch for the very first time

  • Weather – synced from your smartphone you get a current hourly weather forecast covering 2-days ahead. The forecast conditions cover wind direction/strength, temperature, humidity and rain/cloud/sun indications. It’s straightforward but useful information. Maybe it could be improved by having a wind-direction data metric that you can place on your favourite workout screen or added to the compass.
  • Fuel Wise  -The new Fuel Wise features and similar ones from competitors always sound useful to me. I just find that I never quite get around to setting them up and using them as I exercise. My logic is that I tend not to want to trust any manufacturers calculations and then promptly go off on a 3-hour ride with zero nutrition. #Sigh. There are several components to Fuel wise as well as the ability to combine automatic and manual alerts.
    • Preparation – ahead of your planned workout, Fuel Wise will give you an indication of the likely carb consumption as a per-serving amount and interval between consumption. A planned workout could simply be your estimate of the likely duration and intensity before you head off. This is one more fiddle at the start of a workout but in reality, it’s a nice PRACTICAL solution as the alternative is to follow a structured workout and many of us rarely do that.
    • Workout – During workouts, the carb alert is displayed automatically when needed and based on Polar’s estimation of your calories burned and the likely fuel source for them. So we are looking at estimating the calories from your heart rate/weight and increasing the ratio of carbs used at higher HR levels. Polar has always been, in my opinion, one of the better estimators of calories burned during exercise so providing you get good HR figures from their HR tech and have your zones and weight set correctly, the guidance given here should be actionable.
    • Workout – Hydration is certainly also important for longer duration exercise, however, we all have different sweat rates so, yes Polar could have got very clever here by using a combination of efforts and the ambient temperature but they didn’t…and you just get a manual alert which you might have preset as a reminder to repeat every 30 minutes. You’ll probably only need to change this duration as you progress through the demands of different seasons. So if you set all this up ..it’s a nice feature.
    • Post Workout – There are also summaries of the Energy Sources at the end of your workouts and in more detail on Flow. You can monitor changes over time or…ignore the data. I suspect the majority of recreational athletes have little idea of their true carb (or hydration) needs and so it might be prudent for many of us to at least consider Polar estimates of our workouts’ fuel consumptions, make some small changes and see if we perform better (hint: you will 😉 )
    • Here are two nice charts on the Polar app. First, for a running workout where I did some hard hills, you can see the significant switch to CARBS during the harder efforts. The second one is for a bike ramp test and it’s quite interesting to see Polar’s interpretation of the fairly dramatic switch to carbs (plus a bit of protein)


  • Hill Splitter is Polar’s first foray into environmental profiling ie looking at how you perform over differing environmental conditions. This is one of the sports tech areas that we might see coalesce and develop more in the years ahead. I guess you have to start somewhere and Polar has started with hills – which is sensible as hills significantly impact your performance.
    • Unlike when cycling and following a route, the big problem with running up a hill is that you typically don’t exactly know what’s coming – in terms of the precise grade and surface.
    • Hill Splitter seems, to me, to be designed mostly for running and, whilst it will work on most people’s definition of a hill, it seems to work best for hill reps. Each rep is automatically detected, numbered and recorded. So you get the special Hill Splitter screen when you are going up (or down) each hill, it’s a BIG shame that the Hill Splitter screen cannot be customised, for example, to add a running power metric.
    • Hills are effectively recorded as a new series of numbered laps which can be analysed individually in Flow – remember Polar has always recorded multiple lap tyes ie MANUAL laps and AUTOMATIC laps, unlike Garmin. There is some other interesting stuff here too which I will cover separately over the coming days.
    • So yes, you can still use live metrics for VAM or GRADE or power on a separate screen but Polar’s new Hill Splitter does add something new to both running and its analysis.

Here is a link to a detailed look at Polar’s Hill Splitter.


Polar Hill Splitter – All you need to know and more


  • KOMOOT Support & Turn-By-Turn Support – Komott support is already partly rolled out to the Vantage and V650. Just as you can import your favourite STRAVA routes into Polar Flow and onto the Grit X/Vantage then you can now also do the same thing with Komoot. The ‘special’ Komoot support with Grit X is that you can also get TBT instructions thrown in too. Polar need to work on including the forward elevation profile here but apart from that all is cool in a simple kinda way. Komoot is probably the most beautifully presented routing platform, it looks WAY better than STRAVA but the public content (routes) on it are few and far between in my part of London. Putting that to one side, however, on the few occasions I have curated my own routes in Komoot it has chosen sensible options for cycling and, interestingly, when creating a route it shows 3 options by default; one for cycling, one for walking and one for running…this is quite handy when you are planning to cycle somewhere you shouldn’t be. Apparently. Ssssh.
    • I thought this needed a premium account with Komoot to work (it doesn’t AFAIK). You should get a 30-day freebie with the Grit X but I haven’t enabled it and all seems to work fine. #Confused. I did unlock my local region for free on Komoot which you can do once, maybe that was it?
    • The breadcrumb route navigation already supported from STRAVA routes is basic. Komoot routes are just another source for displaying in exactly the same way, the Grit X just about does the job for simple routing needs. Yes the TBT arrow helps a little bit but I was a bit disappointed not to see street names in the TBT instructions.


Here are screen images of the Grit X showing some of the new features, most of which are self-explanatory.

Polar Grit X Accuracy

Despite the modified Precision Prime sensor, I haven’t noticed any material difference to the accuracy from the Vantage running the latest Vantage firmware.

The following post gives some accuracy feedback with the latest production firmware. Perhaps the most interesting thing in there is my first formal test with GPS+GALILEO which had normal-good results (Garmin-equivalent accuracy)

Polar Grit X Pro Titan – Accuracy, some initial thoughts



Polar Grit X Specifications & Resources

Here are the Polar Grit X specifications which are mostly hardware-related, plus a link to the manual once it goes live.

Note the initial specs on Polar’s site are not fully correct.

  • Measurements: 47 x 47 x 13 mm
  • Weight: 64 g with the wristband, 44 g without a wristband.
  • Materials: Extreme high strength stainless steel case (looks great). Glass fibre reinforced polymer back cover (looks less great).
  • Display: Always-on colour touch display. Laminated Gorilla glass lens with anti-fingerprint coating, protected with extruded stainless steel bezel with lugs. Option to have backlight always on.
  • Display Size 1.2”, resolution 240 x 240.
  • Battery: 346 mAh Li-pol battery. Battery life up to 40 h in training mode (GPS and wrist-based heart rate) or up to 7 days in watch mode with continuous heart rate tracking. Multiple power save options available.
  • Processor: Unknown, however, the Grit X feels faster and smoother to use than the Vantage V Titanium.
  • GPS & Barometer: Integrated GPS, GLONASS + Galileo (yep). Assisted GPS for fast fix times. Barometric altitude, incline, ascent and descent.
  • Connectivity: Bluetooth Low Energy. Custom USB cable for charging and data synchronization. No ANT+
  • Watch: Time and date. Alarm with snooze.
  • Sensors: Compatible with all standard BLE heart rate sensors and running cadence and power sensors as well as cycling speed, cadence and dual-LR power bike sensors.
  • Wristbands: Durable and comfortable silicone, options for fabric. Supplied one is nice.
  • Sizing: S: wrist circumference 130-190 mm, M/L: wrist circumference 145-215 mm
  • Compatible with standard 22 mm quick release watch bands (this is not strictly true as the pins vary between manufacturers eg my Coros strap fits Polar but my Amazfit strap does not and they are all 22mm)
  • Durability: Operating temperature: from -20° to 50°C. Temperatures below -10°C may affect battery life and performance.
  • Durability: Tested against military standards (MIL-STD-810G).
  • Onboard Temperature Sensor – Vantage has one too, records data to Polar FLOW, influenced by body temperature. Not taken from weather forecast info AFAIK although STRAVA can add this if you like.
  • Water resistance: officially now WR100, up to 100 m (elsewhere Grit X is quoted by Polar as WR50 but it is sold as WR100)
  • Magnetic compass (only available during a workout, requires frequent, annoying calibration)
  • The barometric altimeter is automatically cross-calibrated by GPS within the first couple of minutes of a workout. Altitude can be manually calibrated from the fullscreen altitude training view. Altitude is corrected when reported in Polar Flow.

ie It’s a Polar Vantage V on caffeine.

Note that the Grit-X/Sony GPS chip also supports and uses better positioning from SBAS and Galileo, even though it’s not yet mentioned on the official specs.

All sensible BLE sensor types are supported. I’ve not checked this but I would assume that dual-sided bike power meters still support LR balance (not the case with Suunto). STRYD is supported via BLE and STRYD running power overrides Polar’s own power calculations if present. STRYD can accept a manual calibration value. Polar still always automatically pairs nearby BLE sensors, even if you remove them it pairs them again.

Well, I Never Knew That

Here is a whole post full of Polar Grit X and related trivia. You will learn something new in there somewhere.

Polar Grit X – I never knew that

Polar Grit X Pro & Grit X Pro Titan

October 2021 saw two new Grit X versions, the Grit X Pro and Grit X Pro Titan. These two new models have the same features and the Titanium model has some lighter titanium parts on the shell, a modified bezel and $100 added to the price tag…it’s a SWEET watch though!

These two new GRit X Pro models have the exact same features as described above on the original Grit X. All new Grit X Models boast these new features

  • New Location Dashboard
  • New Sunrise/Sunset Dashboard
  • New Trackback Navigation Options
  • New Elevation Profiles when following Routes
  • New Tests from Vantage V2: Cycling, Leg Recovery, Running, Orthostatic
  • New HR broadcast
  • New Music Controls
  • New Recovery Pro
  • Some other minor changes

The original Grit X is good but these extras are worth paying the premium if you can afford it.

Competitor Price Comparisons

RRP prices are about right, perhaps even on the ‘good’ side of right at US$429/GBP379/Eu429 incl. 30-days free Komoot premium. Compare this to $499 for the Vantage V and $279 for the Vantage M

With the Garmin Fenix 6 Pro coming in at $700rrp and the Garmin Fenix 5 Plus at $750rrp then they, perhaps, represent the next step up in terms of bundled mapping features. The F6 Pro/F5+ have onboard MAPS and I wouldn’t recommend the earlier Garmin Fenix 5 ($499) which is perhaps more of a directly-comparable device to the Grit X with no onboard maps. Garmin is simply more expensive.

Perhaps at the other end of the scale, you could consider the Sigma Sport id.FREE which also has breadcrumb route guidance and links to Komoot for around $150 or the uglier Garmin Instinct.

The sensible choice, if you can afford it, is ‘somewhere in between’. The Garmins are well-featured but too expensive and the Sigma Sport id.FREE/id.TRI just doesn’t have the durable hardware format and platform as offered by Polar.

Somewhere in-between‘ includes the Suunto 7 (or any Wear OS watch) or the Apple Watch 4/5. You DO get full maps on those watches when there is an appropriate app installed but the plummeting battery life will always be on your mind and further decimated whilst displaying a map AND simultaneously navigating.

That leaves Coros and also the Suunto 9 ($499 currently reduced to $349) or 9-Baro ($549) or maybe even the smaller Suunto 5. I really like the Suunto 9-Baro but you might bemoan Suunto’s new, improving app platform despite being impressed with its superior hardware package. Polar simply delivers more on the sports insights than Suunto and it does that on a better platform. So Finally we have to consider the Coros Vertix at $599, which is perhaps priced too high but worthy of your consideration.

So, Polar Grit X is priced sensibly compared to the competition. If you haven’t already bought the Vantage will the new features convince you to try the Polar Grit X?

Polar Grit X Review

Polar Grit X Review – My Thoughts

Grit X: It’s impressive. I like it. For my personal usage I’ll stick with the Vantage M/V which suits me as a triathlete. If you buy one you probably won’t regret it for the money.

In some ways, I am glossing over what Polar has already delivered with the Vantage series. There is much AWESOME, existing functionality that is now on the Grit X too. The unspoken advantage of the Grit X is that it seems better-powered and more smooth than the Vantage.

The new features are generally nice with scope for further enhancements. I think the issue with them will come from existing Vantage owners asking “Why can’t the Vantage V Titanium show me today’s weather on my road bike ride” and “Why can’t the Vantage V Titanium show me nutrition alerts in my race“. Those are good questions that Polar need to answer, although buying the Grit X is an answer in itself. Vantage owners should note that they already get Komoot support (just not TBT), so that should keep everyone partially happy and similarly, whilst interesting, the post-workout hill-splitter stats bring little new to the in-exercise experience in reality.

Polar Grit X Review Specifications
Impressive-looking Precision Prime sensors that your training buddies rarely get to admire

Many reviewers underestimate the importance of battery life to Ultra Runners. I probably underestimate it too…but Polar clearly have listened to that target market and we’ll have to wait for ultra runner feedback on the Grit X to see just how good the extended battery life modes are in real-world usage. Tentatively their spec looks good.

Many reviewers also over-hype the full onboard maps on competing Garmin watches. In my opinion, they’re not as handy as you might expect. I wish I could entirely disable the maps on my Garmin 945 but even when I try to use them, it’s difficult with relatively poor (free) maps on a small watch format. Thus Polar’s Grit X compromise with STRAVA breadcrumb routes and KOMOOT TBT routes is probably a fair one that will be useful for some. If you have the Strava/Komoot apps on your phone in your pocket then you can get a new route to your Grit X if you NEED to. Although, having said all of that, the beauty of a routable map on your watch is that it can route you back on course…Grit X can only do that via the /Strava Komoot smartphone app.

I also am reticent to recommend ANY watch-based solution for navigating on an MTB, a dedicated LARGER-FORMAT bike computer on the handlebars is clearly better. However, the Grit X is a nicely-durable and good-looking watch that certainly complements the trail biking experience.

Polar Grit X Review - Summary

Polar Grit X Review

The Polar Grit X nicely supports serious athletes and committed adventurers, perhaps not extreme explorers. The Grit X looks great on the wrist and the Polar FLOW platform is great for athletes and active people alike.

67 thoughts on “Polar Grit X Review – covering Grit X Pro, Grit X Pro Titan

  1. What’s the quality of the display? I.e. will we middle-aged varieties be able to read it in outdoor conditions without having to whip out our reading glasses (which I have yet to take along on a run)? I gather the Vantages aren’t very forgiving of older eyes, is the Grit any different?

    1. Excellent point. I am 51 and have trouble reading the Vantage V on a run. I heard from another review (DesFit or Chase the Summit on YouTube) that the brightness has been increased.

      1. I don’t think you’re a member of the over-50 club though! 😀 I’m having increasing trouble with my Spartan Sport and this will only get worse over time. Contrast on the Grit X seems to be suboptimal again according to a youtube review I just started watching. What a pity; I’d really like to be able to use the Polar ecosystem! As it is I’ll probably be heading for a Fenix 6 after all.

      2. hey there
        again, i find the screen metrics in training readable (quite good) and the backlight can be set to always-on if needed (I don’t do that except when taking photos).
        the small explanative text that comes when, for example, you are reading CARDIO LOAD feedback is very hard to read on the watch as it is too small for me. But of course you can read simialr feedback on Polar FLOW.

      3. I received the Grit on Sunday (5/3). I’m 52, and had previously been using an Ignite / M430 combo. I find the screen to be VERY dim which makes the text VERY difficult to read. Sitting in my office during the day, the smaller text on the Cardio Load screen, the FitSpark screen, and the Heart Rate screen is basically illegible even with the backlight on.

        I’ve reached out to Polar with my concerns, but unless this unit is defective they have not solved the screen issue. Most likely, I will be returning it. Which is unfortunate, because I feel that the fit/finish and the GPS accuracy are very good.

      4. @Eric: Thanks for your comments, this is very interesting. I found Kofuzi’s review on Youtube the other day and he finds the Grit’s display slightly brighter than the Vantage’s… but he’s manifestly not over 50.

        Anyway, if the Grit X is as hard on middle-aged eyes as you report, I guess I’m headed towards Fenix 6 after all. That said, the legibility of my current Spartan has improved by orders of magnitude since I stuck a single +1.75 Hydrotac onto my running sunnies on the side where I wear the watch. It makes a huge difference and I’ll be keeping it regardless of which watch model I get next!

      5. @tfk, good to know the F6 is brighter. Question: does Garmin display Stryd metrics like ground contact time and leg spring etc.? Or do you still have to offline sync to get that data?

  2. Any particular reason you leave out the Coros options in your pricing discussion?

    Really interested to see your accuracy results. May finally dump my S9 if this thing turns out to be decent.

      1. Not seeing an updated file w Grit X results, but I can wait for the formal review 🙂

        Do you know if you can save waypoints/pois through the watch?

  3. Do you think there would be a hardware update to the vantage v or suunto 9 coming soon to compete?

  4. Do you see any new rival watches from Garmin anytime soon that would compete with the Grit X or Vantage?

    1. yes https://the5krunner.com/2020/03/06/march-2020-sports-watch-update-all-new-current-bike-run-tri-fitness-models-with-gps-rumors-replacement-dates-for-garmin-polar-suunto-wahoo-fitbit/

      745 for multisports
      next gen Instinct for outdoors
      you asked before about the 955/lte (prob 2021)
      fenix 7…maybe fall but almost certainly not.

      any new garmin outdoors product will only be adding a niche feature or two.
      Fenix has ALL the features…if you can find them in the menus and afford the price of a non-scratchable PRO version then go for a fenix now.

      1. Which one would you prefer for running, hiking, pool swimming, quality, flow vs connect? Grit or FR945? With prices dropping for FR945, they are not so apart from each other. Thanx.

      2. i use a 945 to record my activities. wish i hadn’t changed from 935 as 935 could be connected as a drive.
        anyone that makes a decent watch which records everything to dropbox (or direct cable connection to a windows drive) gets my business

        i’ve been wearing grit x 24×7 for a while. i like the looks and feel

        flow vs connect – flow any day.

        945 price falls…might mean the 955 and 955lte are imminent (tho i dont think so)

  5. Thanks for the review, looks like a nice piece of kit. However the events of the last two months have made Garmin Pay my new best friend as no shops want to deal with physical cash anymore. Means my 645 (2 years old & counting) will be staying with me & I’ll be eying up the 655 assuming I still have a job whenever it comes out!

    1. indeed so.
      the other positive side of life is that I now know the names of all the local delivery couriers from every major firm (hermes, amazon, fedex/tnt, ups, royal mail)

  6. Another nice looking watch by Polar. They should seriously consider custom watch faces to go with the these cool hardware designs.

    1. yes there’s been very little innovation from them with watch faces and it must be relatively cheap and easy for them to do. Polar have certainly said that they realise the importance of personalisation/appearance and that’s why they have the interchangeable bands

  7. Will this reveal have impact on speeding up the launches of garmin new products? Are they still on the map? Interested the most in Garmin 745?

    1. It’s a straightforward (and good) question and the answer could get real interesting and real complex (and long). here’s a short version

      the Garmin development cycle is likely 2-3 years depending on how and where you start it. Products can get canned in that process. Competing product releases can affect Garmin launches BUT a launch is highly involved and complex and to change it is NOT trivial…much easier is for Garmin to react with a promotion of some kind to counter the new product.

      Having said that all companies are somewhat porous with any supposed secrecy around their new products, so Garmin will have known about the generality of Grit X for at least several months. I knew about it a couple of months ago. So Garmin do/likely did have scope to react in similar such timeframes.

      The new Garmin products are ALL on the map. and this link tells you about the imminent ones https://the5krunner.com/2020/03/06/march-2020-sports-watch-update-all-new-current-bike-run-tri-fitness-models-with-gps-rumors-replacement-dates-for-garmin-polar-suunto-wahoo-fitbit/ . sometimes either my info or assumptions are wrong but it’s generally a good steer for you guys ie the info is ‘about right’. so the 130+ and 1030+ are probably next, probably the 745 follows soon after. But, for example, the 745 could be september and the 655 could be 2021.
      market conditions: clearly tradeshows and spring/fall are the time for new releases in a normal year. normally you wouldn’t release a product in the summer as people are on holiday, etc etc but this year could be different if we exit lockdown then. In reality there will be few triathlons until later in the summer…if at all. it would be sensible to tentatively schedule a new watch for that period.

      1. So you are basically saying that it all went according to plan with Polar and Grit X – regular spring release – not something that was trying to outrun Garmin to the spring-finish-line…

        With Garmin the last spring/fall “sequence” was:
        2019 April – Edge 130 and 830 , Forerunner 245 and 945
        2019 August/September: Edge 1030, Fenix 6, Vivoactive 4

        if Garmin was to follow their usual routine (if Polar did, why wouldn’t Garmin? – although maybe Polar are more determined thinking they need play catch-up in the “trail” segment) we should be seeing something immediately..

        Postponing until summer doesn’t make sense as you were saying, merging it all into fall – same thing.

        And since the products are already developed (and paid for – R&D costs) they need to get it out no matter the COVID situation or they will be admitting future losses based on extending the product cycle..

        Just thinking out loud..

  8. What is the physical size of screen (Glass size, diameter, edge to edge)? How to compare it with Polar Vantage? Is Grit X’s screen glass bigger or smaller than Vantage?

  9. Hi!

    Thanks for the review! Great work as always. I have one question. In the Conclusions you say this:

    “Grit X: It’s impressive. I like it. For my personal usage I’ll stick with the Vantage M/V which suits me as a triathlete. If you buy one you probably won’t regret it for the money.”

    Why would you prefer the vantage over the Grit for triathlon? Or are you just talking about not doing an upgrade?

    1. last year i actually used the M for some races and training. pace, power, cadence….my needs are meagre. i like the full recovery piece in the VV. i like the aesthetics of the buttons in the VV (GX work better tho).

      as the days go by. the reason why i would upgrade to the GX would just be that it runs more smoothly. from a personal perspective, which is what you asked for, the more you see of all these new features and understand them and their benefits the harder it becomes to find ones that you’d actually use. it becomes the APPARENTLY SILLY things that make a big difference..like speed of the device or buttons or the ability to use dropbox to access workout files and upload routes.

      but…people buy garmin because they have all those features that you might possibly perhaps maybe could, just could, one day use. but don’t.

      1. Thanks for you answer. I couldn’t agree more. I’ve run away from Garmin just Because of that, which makes their platform (connect) confusing. I love the design, that Trade off between functionality and clarity of Flow.

        I bought the VM and sadly returned it because I found the lag when navigating the watch frustrating (True that I bought it straightaway, a few days after its launch) So of GX has succeeded in solving that issue, it might be muy next gps Watch.

  10. Hi. Great review, thanks. I don’t see any mention of a metronome function for running. Is there one on the Grit X?

      1. Is a shame for a serious running watch to be missing a pretty basic feature. I guess the same goes for the Vantages?

  11. This could be my first serious temptation to move on from my Garmin FR630.

    No payments flim-flam (in any case mostly useless here in the UK, where exactly one reasonably mainstream bank and a handful of niche players are signed up).

    No music flim-flam (just my preference, YMMV)

    Adds barometric altimeter 🙂

    No touch screen while in recording mode 🙂

    Just focus on the job in hand 🙂

    1. PS, in terms of the focus on just being a sport watch (no music or payments) this is kind of what I hoped the once-rumoured/apparently-canned Wahoo watch might have been (obviously this has the Polar platform behind it where Wahoo leaves more to third parties). Guess we’ll never know…

      1. I guess we’ll never know indeed…
        the coros pace is like the garmin 235 which is perhaps the kind of device you are describing.

        features are often over-rated and always over-priced.
        (I just made that up and am very proud of myself)

    1. Apex Pro you get pressure based storm alerts, preset nutrition reminders, compass outside of an exercise, breadcrumb navigation and an insane standby battery on top of a platform that’s best served just exporting to other tools

      Grit X you get nutrition alerts based on effort level, tbt guidance (if you buy in to komoot apparently), and a fairly robust and vetted native training nd recovery platform

      This is the very debate I am having.

  12. very cool. I’m still rocking my Spartan trainer, but this watch is ticking many boxes for me, which i was struggling to find in a complete package.

    Garmin to me is mainly overpriced and in most cases underused by most owners. This watch seems like a sensible priced and featured alternative to step up my game a bit. Plus the rugged design will finally (maybe) draw me back to polar flow.

    Though I’m surprised that they deliberately cut features from the vantage V .. Maybe there is a high end version in the pipeline? GX+? 🙂

    That said i hope that the current situation will allow my activities to get back t

    1. high end version??? IDK, maybe. it would make sense. maybe it would just be a titanium case, it’s very well made as it is now.
      I would say Garmin is over-priced too but they sell LOTS. So economics 101 tels us that you and I are both wrong 🙁

      1. True 🙂
        looking forward to your full review. They usually include topics not many touch and are great to read. Hopefully it turns out to be the great (long-term) alternative it seems to be right now

  13. Is it possible to use stryd of trainingpeaks structured power workouts on the Grit?
    Newbie in Polar-land 😀

    1. it’s one-way TO training peaks right now.
      I’m anticipating this to change and become 2-way fairly soon.

      In Garmin: training peaks and final surge both support creation of running workouts with power BUT only the descriptions of what each power interval appear on your watch ie you are not alerted during the workout if you stray from the power zone

      this whole area is one of the developing ones this year.

      I expect to see lots of integration with garmin in lots of ways and then also lots of clever integration with final surge. things tend to happen first with links to training peaks but this might start to change in the non-garmin world.

      1. It’s a pity that products with high-end features are released without worldwide connectivity used by amateurs and pros…. structured workouts in a device as expensive as the GX a must-have for the segment of the market that Polar intend to compete in. Garmin already offers that feature in cheaper models like as the 245 or 645 for more than a year… =\

  14. “training plans and customisable workouts, all of which can be executed flexibly on your watch”. No się, its worse than on v800 or even m430. You cannot freely and flexible run workout – you cannot switch phases! You cannot flexibly run a workout because there is no diary so if its not on todays plan you wont be able to run it! This high score is a misunderstanding!

    1. points taken but those are niche features,
      products can’t have every feature, i agree it is nice to have every feature of the equivalent earlier model (v800) – polar have tried hard to do that with vantage fw v5 and now the extras on grit x
      favourites give some flexibility to execution

  15. Is the vibration the same as on the Vantage? Always struck me as more loud and buzzy than actual vibration.

    Any thoughts on comfort compared to the V? Band is a little stiff on the V, seems to bother me more when sleeping.

    1. similar if not the same. configurable in flow

      Grit X has a classic band-pin attachment whereas the V is a customised strap. grit will be similar to most watches
      I prefer comfort and looks of the V but like the grit x too.

  16. Thank you very much for the great review.

    I was wondering whether the Grit X/Fitspark would work for the following use case, as you mentioned in another post that Fitspark still works well even beond the advised 5 hours.

    I use a low volume training Ironman training plan on Trainerroad. I think that that the bike workouts are really good but I am find the running workouts a little too unspecific.

    How well do you think would Fitspark work to generate the relevant structured running workouts, if I were to record all workouts on the Grit X?

    Thanks a lot!

    1. fitspark is not designed for someone doing an ironman

      you’re going to be training AT LEAST 10 hours a week and spending LOTS of money. my suggestion is to follow a ‘proven’ plan or get a coach or, if you are self coaching, then get some other tools which specifically look at your recovery status (eg elite hrv…free app) and a simple means to measure that you are progressing and periodising and stimulating your body in the right training zones

      1. Thank you very much for your super swift response.

        I have done my first Ironman last year and I am indeed training quite a bit more than the 5 hours suggested for Fitspark, which is precisely I wanted to check with. You have confirmed my suspicion that Fitspark is not for me.

        For now, I will stick with the TrainerRoad plan and measure training load with my Garmin 945 which worked well for me last year. I only wish that there was something that was a little more dynamic based your current physiological state (I guess that would be getting a coach but I am not sure that I can justify the expense just yet 😉 ).

        No reason to buy a new gadget unfortunately!

  17. Gotten a Grit X to play with and wanted to share two issues that I came across:
    – Pool Swimming: I have just done a swim in the local pool which finally opened. I did a continuous swim of 40 min of which the Grit X marked 10 min as rest, which cannot be correct. I had problems with incorrect pool swim metrics with the Vantage V but had expected these to be fixed by now. I guess that there are probably not many people using the Polar watches to swim with.
    – Indoor Trainer: For my workouts with the Kickr Core, the Grit X records twice the amount of power that I actually provide. A quick search on the Trainerroad forums shows that this is another problem that the Vantage V already had.

    Has anyone else seen these issues? Thanks!

  18. Hi

    I’m using GritX from september, I like the watch and I love Polar Flow. I’m trail runner and I have switched fom Suunto (Spartan Ultra) just to move to Polar Flow and try the Nightly Recharge and Training Load. Love it, they helped me a lot to adapt training load during the week. But (always there are “buts”) I miss the navigation capabilities of the Suunto (breadcrumb track…) and the barometer ant temp data. Now I’m thinking about to give a try Suunto 9 Baro, how do yo compare 9 Baro to Grit? And, more important, can I have similar metrics (Rest and Sleep, Training Load) with Suunto App compared to Polar Flow? Perhaps I’ll stick with Grit, I think at this moment I priorice that training features over the “mountain” features… Dilema!!!
