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.
The new health sensing system samples heart rate every five seconds all day and HRV every five minutes, feeding a 0–10 readiness score.
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).
A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.
Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.
Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.
The right pick depends on what you optimize for.
