How this is made

The short answer and verdict are derived from where those signals diverge — not written by hand for either product.

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.
— best for: Outdoor endurance athletes — hikers, trail runners, and cyclists — who want a durable, feature-complete training watch with best-in-class navigation and are willing to pay for premium materials and a sharp AMOLED display.

On Grit X2 Pro: GPS accuracy drew different impressions: DC Rainmaker devoted significant testing to it and noted Polar's antenna claims, while The Quantified Scientist found earlier sensor-set results on the identical sibling watch to be relatively poor, pending full independent retesting

Have been using this watch for majority of this year after being long time Garmin user. Overall I'm very happy with the watch, it's functionality, accuracy and reliability. Battery life is not quite as good being AMOLED but its understandable. All in all its been a good purchase and I'd recommend it to athletes. John · REI
