Polar - Grit X2 Pro

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.

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

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.

Love the Polar Grit X2 Pro Titan with leather wrist!

I think you don't find many reviews on the Grit X 2 because it is the same software and hardware than the Grit X 2 Pro and the other current generation watches, so the software and features are the same and the other watches came first, hence the reviews on those ones. The only thing that could change is GPS accuracy as the antenna placement will depend on the watch design, but I wouldn't worry about it as all of the current generation watches have had good GPS accuracy, and HR is usually better on lighter watches as there is less inertia when moving anyway. When it comes to battery life I think their claims are close to the real use data, keep in mind their claims are not using AOD though.

Hello 👋🏼 I have the Grit X2 Pro and the H10. Honestly no problem, heart rate and sleep data are excellent. Like many users, the only criticism we have of Polar: their Polar Flow application, which is very old but goes straight to the point and without any fuss 😂

I've had the Grit X2 pro since May 2024. No regrets. Many hikes including Fontainebleau. Excellent GPS and Cardio

Same here Grit X2 Pro Titan

When I had a Grit-X2 Pro I set it do Nightly Recharge as it was just more convenient

I would go for the Grit X2 (latest, just a bit more expensive than the M3). Polar watches have the same OS, so the only difference will be design, materials (for sturdiness go for the Grit X2), weight and battery life. For premium feel and long battery life go for the V3 or Grit X Pro. Pacer is old, it has MIPS display, the above mentioned have nice AMOLED. Ignite does not have maps and navigation. You cannot import workouts to polar flow platform, but if you wear your watch during workouts it will sync them to Strava. You can even pair your compatible sensors too (H10, speed/cadence), so you won’t miss any data.

This is exactly my use case as well. No need to wear the chunky Grit X2 Pro all the time but still all data in one app. 

It enables me to wear my automatic watch while still tracking activity throughout the day. I will use my Grit X2 Pro for sports. 

My use case for it is as a complementary device. I will wear it in daily use and switch to my Grit X2 Pro for sports (except Water Polo where I use a Verity Sense). This way I can wear my automatic watch again instead of a chunky sports watch. 

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.

When I was swimming regularly in a 25m pool with grit x and vantage V, I found that taking a little longer from pushing off from the side before taking the first stroke on each turn makes a huge difference to accuracy of recordings. Only issues I’d ever have were the occasional missed turn.

I use a Polar Grit X. Reliable and robust and easy to sync with a phone. Already survived multiple crashes. Compared with other Polar models the Grit-models are more robust. It’s not a smartwatch but a regular sportswatch the can receive notifications from a connected phone. Imho a real smartwatch is too fragile and/or too expensive for offroad usage (with chance of crashing). The Grit X works fine on most routes/trails. Only when S-curves are very tight it gets confused and cuts off the route and in the end the total distance shown is not correct.

A fairly old and battered Polar Grit X Didn't want to splash out on my first sports watch, so bought this second hand for under $100 and it does the job for me!

Well, I compared my polar gritx watch to polar h10 chest strap in a threshold session, the difference was still within 1-2bpm, mostly exactly the same. The chest strap was slightly faster, but unless I'm doing 10 second intervals I don't really care that much. It is also more hassle, more uncomfortable, and more susceptible for dropping data in regular use. I just gave it away.

I don't know how to answer that. But basically all modern Polar watches have same standby time. Pacer, Pacer Pro, Ignite 3, V2, V3, Grit X, Grit X Pro, Grit X 2. But if you go back in the lineup you will have a lot more standby. But that doesnt make sense to buy that old today. How ever, the GPS-time you can do a workout differs more. But, I have had best battery on Grit X. 30-40 hours races done with that. Wrist HR and just run. But I think you get same from basically all "top-line" watches.

I am not an apple person but the Apple watch is routinely the best one on the market from independent studies and scientific studies. Personally I use a Polar GritX that's a couple years old.

Don't get a Polar. My Grit X lap tracking is all whack with no way to fix the data, and the strokes misinterpreted all the time. Maybe it's just my shitty form.

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.

Its about as good as you are going to get. Apple does lock certain features to apple watch only - so an apple watch ultra 2 is an alternative option you can look at - as does include recreational diving features - but not as much as the fenix 8, and you can cover the gaps the F8 misses via 3rd party apps - but does leave out the cohesive eco system garmin provides - and considering that you barely mention any smart features would then say you are looking at the right watch (definitely from fitness tracking and progress tracking point of view). Fishing - actually it does - you can log your catch and log the spots where you catch.....

All garmin have a built in coach for running - think C25K but does up to half marathon distance, then F8 incldues a Daily suggested workout option which you can then add a race event to it, to get the DSW to try and get you to peak for your event - so if you want a hassel free experience and a watch to build your training programme - hard to beat what garmin offers. Hiking- get offline maps and offline navigation (think satnav from car on watch) - so can create routes and get tbt directions on watch and via audio. Plus love the climbpro feature. Maps will work with all outdoor activity so can use for paddling as well as running / hiking etc (have a couple of paddle routes for when on canals / rivers especially canals in towns - great way of seeing parts of a town via water). So yes there isn't really anything else that comes close to matching it. Nearest alternative options would be apple watch ultra 2 (and losts of 3rd party apps); polar grit/vantage and coros pace pro /apex pro / vertix all include built in training systems and with training metrics and analytics like garmin to track progress; suunto at this stage is training metrics and analytics - though their suunto ocean is a full dive watch (garmin equivalent is the descent mk3 which is basically a fenix with full dive capability);
