Symptoms

  • Band slides around on the wrist
  • Band leaves deep marks or feels uncomfortably tight
  • Sensor readings are inconsistent due to fit
  • Watch face rotates around the wrist during activity

Likely causes

  • CommonBand adjusted to the wrong hole or link lengthMost bands have multiple adjustment points that are easy to get wrong initially.
  • PossibleStandard band doesn't match wrist size wellBundled bands are sized for an average wrist and may not fit smaller or larger wrists well.
  • PossibleWrist size changes with temperature or time of dayWrists can swell slightly in heat or after exercise, changing fit.
  • Less commonWrong band length purchased for a metal or link-style bandLink bands sometimes need professional link removal to fit correctly.

What to do

  1. Adjust the band to the next hole or link for a snugger or looser fit as needed.
  2. Aim for a fit where you can slide one finger under the band comfortably, snug but not tight.
  3. For metal link bands, use the included tool or a jeweler to remove or add links.
  4. Try a different band material if the current one won't adjust to your wrist size well.
  5. Reposition the watch slightly higher on the wrist for better sensor contact if accuracy is also an issue.
  6. Check fit again after exercise, since wrists can swell temporarily.
