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).

COROS Pace

AMOLED display at 32g and $249

First COROS Pace with AMOLED — a vivid 1.2" touchscreen in a 32g nylon-band body, making it the lightest AMOLED GPS running watch at this price.

41 hours GPS, 19-day battery

16 more GPS hours than the Pace 3, with 19 days typical use. Best-in-class battery life for a sub-$250 AMOLED GPS running watch.

Multi-band GPS and voice features

Dual-frequency L1+L5 GPS for precise tracking in cities and trails, plus built-in voice pin recording and audio lap alerts — new for the Pace line.

Quick Winner

The right pick depends on what you optimize for.
