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.

Apple Watch Ultra

42-hour battery + satellite SOS

The Ultra 3 nearly doubles the Series 11 battery life, and satellite emergency SOS works even without cellular or WiFi coverage.

Dual-frequency L1+L5 GPS

More precise GPS tracking in urban canyons and dense forests — critical for trail running, mountaineering, and triathlon.

3000-nit titanium-cased powerhouse

The 49mm titanium case and 3000-nit display make this watch usable in full direct sunlight and water depths up to 100m (EN13319 certified for diving).
