What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Exceptionally bright and sharp AMOLED display remains fully legible in all lighting conditions, including direct sunlight
- Premium build quality with sapphire crystal lens that resists scratches; titanium variant is notably light for its size
- Comprehensive navigation suite including offline topo maps, breadcrumb trails, and third-party route compatibility
Reviewers push back
- User interface feels dated and offers limited customisation compared to rivals, with reviewers across multiple channels calling for a visual refresh
- Step counting is unreliable, inflating counts during non-step activities such as cycling, and occasional large erroneous spikes have been reported
- The screen-based flashlight is harder to aim than a dedicated front-facing torch found on some competing watches
A well-built, premium outdoor sports watch with a brilliant AMOLED display, strong GPS, and comprehensive training tools, held back by a dated interface and a few software quirks.
Reviewers praise
- Barometric altimeter enables wrist-based running power and hill-splitter features without accessories
- Route navigation and Strava Live Segments now included at this price point
- Extremely lightweight at 40–41 grams with comfortable silicone band and improved screen clarity
Reviewers push back
- Heart rate tracking struggles outdoors with delayed response to intensity changes and frequent underreporting
- GPS accuracy lags behind competitors in certain conditions
- No touchscreen despite upgraded display
