Why buy each?

Polar Grit X

40-day battery for trail and ultra runners

Five times the battery of the Vantage V3 — enough for week-long mountain stages or ultramarathons without charging access.

Hill splitter auto-detection

Automatically segments your run by uphill and downhill sections, calculating pace and power for each — essential for mountain race training.

Wrist running power at mid-range price

Running power without a chest strap or foot pod — Polar's key differentiator versus Garmin at this price tier.

Google Pixel Watch

Loss of Pulse Detection

Pixel Watch 4 can detect when your heart stops and automatically call emergency services — a unique safety feature not found on Galaxy Watch or Apple Watch.

Fitbit Premium included

Six months of Fitbit Premium comes in the box, with daily readiness score, HRV analysis, and advanced sleep stages.

Pure Wear OS experience

Google's cleanest Wear OS implementation with fast updates, Gemini AI on wrist, Google Maps, and Google Wallet built in.
