The Polar Grit X2 Pro, released March 2023, is Polar's outdoor adventure GPS watch — combining 40-day battery, multi-band GPS, wrist-based running power, titanium build, and sapphire glass at $429. Its hill splitter auto-detects climbs and descents for detailed altitude training insights. Positioned as an outdoor-first alternative to the Vantage V3.
Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.
Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.
Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.
