Each part is rated on one scale for every smartwatch and band, from reviewers' accuracy tests and measured battery life where they exist, what reviewers found, specs and owner reports. It rates the product itself, not how good it is for the price.

Pros

  • Heart rate almost identical to a chest strap
  • Multi-band GPS stays on course under trees
  • Around two weeks between charges without workouts
  • Two case sizes, plus running power and training tools
  • Heart rate matched a chest strap on steady runs
  • Deep training analysis and race-day countdowns
  • About 11-12 days with several runs a week

Cons

  • Chunky case
  • Buttons feel soft and sometimes register by mistake
  • No touchscreen and no colour maps
  • Optical heart rate struggles with sprints and hill repeats
  • Sleep tracking overestimates sleep time
  • Costly for a plastic watch
  • Expensive
  • Against a Polar H10 chest strap the wrist heart rate matched almost every time, and multi-band GPS drifted far less than older watches on roads and forest trails; the best-value serious running watch when tested.

  • WareableJun 2022

    On a 10K it matched an HRM-Pro chest strap for average and maximum heart rate, though fast hill repeats threw it off; GPS wandered a little among buildings but was near-perfect in the open, and sleep tended to be overestimated next to Whoop and Fitbit.

  • Parkrun distances came out right (5.04 km on a 5 km course) and satellites locked in seconds; no chest-strap test was done, but it improves on the 245 in everything except price.
