Our Take
The Polar Grit X2 Pro is a premium outdoor multisport GPS watch aimed at serious trail runners, triathletes, and adventure athletes. Built with a sapphire crystal lens and titanium casing option, it sits at the top of Polar's lineup, competing directly with Garmin's Fenix series and Suunto's Race range at a significant price point.
Key Features
AMOLED always-on display with sapphire crystal glass for scratch resistance
Dual-frequency GPS (L1+L5) for improved positional accuracy in challenging terrain
Polar's hill splitter and FuelWise fuelling guidance tools built in
Up to 140 hours of GPS battery life in Tour mode (reduced in full GPS accuracy modes)
Offline maps with turn-by-turn navigation and route guidance
Wrist-based heart rate plus compatibility with Polar's H10 chest strap
Our Verdict
Buy this if you're a committed endurance or outdoor athlete already invested in Polar's training methodology, or who values heart rate accuracy above almost everything else. If you rely heavily on third-party app integrations or want the most mature mapping experience available, the Garmin Fenix 8 remains the safer choice.
