Heart-rate accuracy is one of the strongest areas: most reviewers found it close to chest straps or other trusted wearables, with only minor or context-specific caveats.
Pros: health tracking accuracy, software smoothness
Cons: LTE connectivity, mapping and navigation
Heart rate accuracy was generally strong, especially versus prior Garmin sensors, though reviewers still noted cycling, descents and strength work caveats.
Pros: GPS accuracy, app ecosystem
Cons: ECG functionality, calorie tracking usefulness
Heart-rate accuracy was one of the strongest areas across reviews, with several chest-strap comparisons looking very close, though one reviewer had serious tattoo-related read failures.
Pros: step counting accuracy, third-party app support
Cons: ECG functionality, LTE connectivity
Heart-rate accuracy was generally strong and often close to chest straps, though high-intensity intervals could show lag or spotty readings.
Pros: water resistance, workout tracking variety
Cons: LTE connectivity, ECG functionality
Heart-rate tracking was usually praised as reliable for casual use, with reviewers noting close agreement with straps or other watches, though some saw lag or older-sensor limitations.
Pros: activity auto-detection, build quality
Cons: blood oxygen tracking, Bluetooth connectivity
Heart rate accuracy is generally strong, especially against chest straps in runs and workouts, though cycling surges and effort changes can still lag.
Pros: GPS accuracy, charging speed
Cons: ECG functionality, voice assistant quality
Heart rate accuracy was mostly good but not flawless; steady-state tracking scored well while intervals and spikes caused some caveats.
Pros: fitness tracking accuracy, wellness insights
Cons: software smoothness, ECG functionality
