Why buy each?

Fitbit Versa

Works with Android and iPhone

Google Maps and Google Wallet on wrist

Turn-by-turn navigation and NFC payments without needing your phone in hand.

6-day battery and Fitbit health coaching

Sleep stages, daily readiness score, Active Zone Minutes, and SpO2 — all on a 6-day charge.

Polar Vantage V

ECG on a sports GPS watch

Polar Vantage V3 is one of the few sports GPS watches with on-demand ECG — usually only found on lifestyle smartwatches.

Wrist-based running power

Running power measurement without a foot pod or chest strap — a significant training metric for pacing effort on hills and varied terrain.

Polar Training Load Pro

The most detailed training load analysis in any sports watch: muscle groups targeted per session, recovery status per muscle, and long-term load trends.
