The Grit X2 is the smaller, non-Pro outdoor Polar: 45mm, sapphire over a 1.28-inch AMOLED, MIL-STD-810H, dual-frequency GNSS, and 32GB holding preloaded colour maps for North America and Europe. The software is identical to the Grit X2 Pro — what differs is case material, screen size, a 50m rather than 100m rating, and seven days of battery instead of ten. The full Elixir sensor set is here and every analytic is free. Then there is the US price. It launched internationally around €479 and reached America in October 2025 at $799.99 — about half as much again — which leaves it just $200 under the larger, tougher, longer-lasting Grit X2 Pro. Outside the US it is the value pick; inside it, the Pro’s extra three days and 100m rating are only $200 away.
Strengths
- Sapphire crystal and MIL-STD-810H in a compact 39g case

Tradeoffs

- 50m water rating, down from 100m on the original Grit X
