Based on 1 year's data from Mar 14, 2026 How it works
Or the Grit X2 (not Pro) as they have all same stuff just in a different case. I like the look of the X2 more than the M3 but it’s a personal preference. If it wasn’t for the GPS the new Loop would work.
Grit X2 owner here. GPS has been rock-solid for me, and wrist HR is accurate for how I train. One caution with reviews: reviewers try nearly every watch and their use case may not match yours. Treat reviews as data points, not directives. I followed the hype and bought a “market leader” Garmin; after \~18 months I went back to Polar. Why? I want enough metrics to make good decisions without the clutter. Keeping it simple is key for me, and the Grit X2 nails that.
No Polar at all?? (I use a Polar Grit X)
This is in line with my observations. Polar Precision Prime is better than Elixir (Pacer Pro better than M3, in my case). I'm glad they went for Precision Prime on the new loop band. Garmin (various watches) was almost always worse than Polar Precision Prime for me.
I bought a Polar Grit X2 Pro because I wanted to support a niche manufacturer but I didn’t know how basic the navigation and maps are on the Polar. Their website is of course dishing out superlatives about advanced navigation and dual GPS and whatnot but the maps are very basic. I’ve seen tons of videos and read as many reviews and realised that maps and navigation are a primary use case for me, heart rate and sport metrics are second. Garmin can do both, Polar lot less so. Saying that, if I have a choice of display readability vs battery, I’ll have to take the display readability.
From a quality perspective, the polar gritx2 pro is superior. I would go for Polar that has more health features and a solid science background. Good recovery tools is probably more important than too much data you won’t use anyway
You can get the Polar Grit X second hand for around 100-150 EUR/USD these days. Never had any issues with HR or GPS accuracy. I also use it almost exclusively for running.
The day you really need a watch in the middle of the woods, in the forest, and reliable, routable maps, etc., then you'll realize that Garmin is years ahead of the crap mentioned in the thread. I've had over 15 Garmins, all Fenix, and I've had Polar Grit X, Suunto, Coros, and those Samsung toys, Pixel, etc. The day you're actually in a real forest and need routable maps and a battery life of two days or more using GPS, you'll never again mention those plastic toys you're mentioning. Until then, keep using those toy watches and considering these idiotic trade-ins.
I have expirience with garmin fenix 6, with apple ultra 2. And now I’m tested fenix 7 pro and 8, polar grit x2 and apple ultra 3. I would say Apple is god tier (espesially if you have apple ecosystem). All works good, all on top level. But not fit me good in a matter that I do a lot of hiking and battery life crucial for me. Other way garmin give a lot of metrics, application also good I would say. But I don’t like design, I don’t like in same way metrics, because tbf they focused more on really pro guys in sport, not needed functionality for me. Other than that - great device, but in my point of view it’s can bit Apple only in battery life, other aspects Apple win win. And polar grit x2, design is ok, not best, not worst, better for me then garmin have. But what I love here Polar flow, it’s looks little bit outdated BUT it’s simple as f. It’s give all things what regular person need plus more, I love how with 1 week of tests it’s start give me advice what really works and not hack me so much, compare with garmin where all advice it’s just burst all trainings and die. And after I check what Polar have else, so I go for myself with Polar Grit x2 Pro 😬 Design is top!

Polar Flow is fine, imo. They have more important priorities than making slick software to appeal to casuals when their watches themselves have many more significant problems. If you want a flashy interface pair with a "fitness band" for tech enthusiasts, go buy a Whoop or whatever and be done with it. It's not happening with Polar anytime soon, in all likelihood. There's been rumors of their poor financial situation for years now. Their hardware and functionality on the existing hardware is a serious issue. Their watches have gotten a ton of heat from reviewers for being far behind competitors in terms of feature set. Even their HRM and GPS accuracy, which was once Polar's advantage, has been matched by competitors. They need to make high quality hardware with features that match the competition and with the appropriate build quality. I've been using Polar devices for over a decade and their build quality on $700 watches like the Grit X Pro is atrocious, with failures in barely over 2 years. Those should all be much higher priorities than trying to cash in on the "fitness band" trend. Besides, if they make it half-assed and with horrid build quality, there's no way they will be able to steal away any share in this crowded market.
I ended up getting a Grit X2 pro but I hope it lasts longer. My Grit X Pro failed in barely over 2 years and the Vantage and M430s I had earlier also had stupid issues like buttons getting stuck. Not to mention the horrible charging port corrosion issues in the M400 days. Polar needs to get their shit together. I honestly don't mind that they have less features (which has cost them a lot of buyers in the market) but loved the tracking ecosystem and was willing to overlook the less "smart" features for the quality. If Polar doesn't get their act together, this will be my last Polar watch. Although I have my doubts the company will even exist if they continue to fall further behind and continue focusing on chasing stupid fads like their fitness band.
