Polar Grit X2

iPhone and AndroidPaid tier: Polar Fitness Program

Polar billed Grit X2 as its most compact outdoor watch when it launched in June 2025. It keeps the Grit X2 Pro's sapphire glass, maps, MIL-STD-810H testing and Elixir sensors, but in a 44.7 mm plastic case with a smaller 1.28-inch screen and battery. The result is lighter, at 62 g with the strap, but rated WR50 rather than WR100.

  • Headline: Polar support: Smartwatch mode up to 8 days, 24/7 wrist HR and notifications on, always-on display off (US product page: 7 d).
  • GPS: Polar support: Performance training mode up to 25 hours, Dual-Frequency GPS on, 1-second recording, always-on display off (US product page: 30 h).
  • Dual-band GPS: 25 h.
  • Polar publishes no single-band or always-on figure; its support figures assume the always-on display is off. Eco training mode: up to 80 hours (single-frequency GPS every 2 minutes, wrist HR off).

The ring’s outer track is the headline claim; the inner two are the always-on and GPS figures as a share of it. An empty track means Polar does not publish that figure. Why the figures differ

Cleared health features

Polar cites no regulator clearance for a health feature on this model. Its heart-rate, sleep and blood-oxygen readings are wellness features.

A clearance says what a feature is allowed to claim, not that it replaces a doctor. Cleared versus wellness features

Features, per Polar

  • 1.28-inch 416 x 416 AMOLED, sapphire glass, stainless steel bezel
  • Tested against MIL-STD-810H
  • Full-color maps with turn-by-turn navigation
  • Wrist ECG, SpO2 and skin temperature (Polar Elixir)
  • Barometer, compass and 32 GB storage

Where the specs put it ahead

  • Sapphire glass and maps in a case 4 mm smaller than the Grit X2 Pro
  • 17 g lighter than the Grit X2 Pro with the strap on
  • Keeps wrist ECG, SpO2 and skin temperature sensing

What it gives up

  • 25 hours of dual-frequency GPS, well short of the Grit X2 Pro's 40
  • WR50, half the Pro's water rating
  • Priced close to the Vantage V3, which has a larger battery
  • Not on Polar's Fitness Program compatible-watch list

The two lists above are drawn from the maker’s own pages and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
