Step counts were described as solid, with one reviewer manually validating them well and another seeing only small variance.
Nightly Recharge is used to reflect recovery from training and stress, giving the watch a meaningful stress-related recovery view rather than a dedicated stress score.
Stress tracking is available and useful enough to mention, but it was not always enabled by default and was not treated as a major differentiator.
Style is better than many Polar watches, with reviewers calling it modern, subtle, cute, and easy to wear casually.
Design reactions were mixed: many praised the slimmer cushion redesign and stronger identity, while others simply disliked the look.
Third-party support is good where it counts, with reviewers specifically calling out integrations like Strava, Komoot, and TrainingPeaks.
