Why buy each?

Fitbit Versa

Works with Android and iPhone

Rare for a smartwatch with real GPS and health sensors to work fully on both platforms — Versa 4 does.

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.

COROS Vertix

140 hours of continuous GPS

No other GPS watch currently on the market delivers 140 hours of GPS tracking — enough for most ultra-endurance events and multi-day mountain traverses.

5-satellite dual-frequency system

GPS + GLONASS + Galileo + BeiDou + QZSS with dual-frequency reduces error in challenging terrain to near-meter precision.

Sapphire glass and titanium case

Military-grade scratch and impact resistance for the harshest environments: extreme altitude, cold, and sustained physical stress.
