Who wins on what

Ranked by what users actually praise

Overall Impression

Design and ecosystem are the watch's strongest assets. Commenters repeatedly praise the Sapphire glass as scratch-resistant and worth the price premium, call the watch attractive and comfortable enough to wear 24/7, and highlight fast charging with minimal battery drain. Many long-time Polar users say Flow's web interface and sleep/recovery graphics beat Garmin Connect and Training Peaks, making it their preferred platform despite an outdated-looking UI on the watch itself.

Heart rate and navigation reliability draw mixed-to-negative feedback. Several users note the wrist HR sensor fails to read through tattoos and takes 20-30 seconds to recover signal loss, with accuracy described as 'not bad but not great.' The routing/navigation feature is called a joke compared to Garmin's offline maps, ClimbPro has calibration issues, and GPS sampling is limited to only 1-second or 1-minute intervals, frustrating users who want finer accuracy control.

Many feel the Pro is a software update disguised as a new watch. A recurring complaint is that nearly every new feature could have been pushed to the Grit X or Vantage V2 via firmware, and indeed many later were, leaving Pro buyers feeling shortchanged. Combined with the small 1.2in screen, thick bezels, no ANT+, no onboard music, and pricing close to Garmin's Forerunner 965, several reviewers argue Polar is now years behind competitors like Garmin, Suunto and Coros.
