Grit X Pro Series

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.
