Why buy each?

Apple Watch Ultra

50-hour battery + satellite SOS

The Ultra 4 lasts roughly twice as long as the Series 12, with up to 45 hours of GPS workout tracking in Max Extended Workout mode. Satellite Emergency SOS works without cellular or WiFi coverage.

Heart rate every five seconds

The new health sensing system samples heart rate every five seconds all day and HRV every five minutes, feeding a 0–10 readiness score.

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 (recreational scuba diving to 40m).

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.
