Three runners found its heart rate matched their chest straps in training and races, and GPS was solid though a notch below the best Garmin and Suunto dual-band watches; best for iPhone users who also run.

The ShortcutOct 2026
Buy it for the multi-day battery and keep it for the health tracking; the reviewer did no own accuracy tests and relies on Apple's study.
Reported by many owners
Common complaints
- Watch restarted by itself for many early owners (during calls, workouts, Maps or even idle); Apple fixed it with watchOS 27.0.1 a week after launch
