Third-party reviews

What we like about Polar Grit X2 Pro

  • Dual-band GPS records clean tracks in dense forest and canyons.
  • Offline topo maps let you navigate without a phone.
  • Sapphire glass and 100 m water resistance suit rough use.
  • The screen at 1050 nits stays readable in strong sun.
  • 40 h of GPS battery covers multi-day trips.
  • Komoot routes sync to the watch for turn-by-turn guidance.

What we don't like about Polar Grit X2 Pro

  • The 48.3 mm case is large on small wrists.
  • There is no contactless payment.
  • The charging cable is proprietary, with no wireless or solar option.
  • Calibration prompts come up often, and finishing them takes a fiddly routine.
  • Open-water swimming accuracy lags behind the pool.

Verdict

The Polar Grit X2 Pro is built for long days outdoors, with sapphire glass, 100 m water resistance and 40 h of GPS battery. Its dual-band GPS records clean tracks in dense forest and canyons. Offline topo maps and Komoot integration let you navigate without a phone, and the screen, at 1050 nits, stays readable in strong sun. The watch also checks blood oxygen and wrist ECG, and the Readiness score shows when to push or rest. There is no contactless payment, and the charging cable is proprietary, with no wireless charging. The case is 48.3 mm across, which is big for small wrists, and the Polar Flow app feels dated. It suits a hiker, trail runner or mountain cyclist with a larger wrist who wants one watch for multi-day trips.
