Why buy each?

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.

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).

Quick Winner

The right pick depends on what you optimize for.
