Polar Grit X2 (45mm)

Beautiful, subscription-free and comfortable — undone by wrist HR that misses intervals. At $799.99, Polar's 2025 model sits at the premium end of the category — the GPS Running Watches we compare run from $249 to $1,199.99. It scores 7.1/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.

Its strongest showing is Display at 8.8/10 — brightness, resolution and daylight readability, weighing AMOLED sharpness against MIP's always-on-for-free behaviour.. The weakest is Value at 4.8/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.

Worth knowing before you buy: DC Rainmaker's optical HR testing was damning: it 'missed every single interval' on 400 m repeats and recorded 3,100 m for a ~1,900 m open-water swim. Budget for an H10 chest strap; and 7 days of smartwatch battery is the shortest in this comparison, and 30 h in full Performance mode is beaten by a $249 Coros. Every specification on this page comes from Polar's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
