Adjusting the Wrist Band Tightness or Wearing on the Opposite Wrist
Some users have reported success in improving heart rate accuracy by adjusting the tightness of the wrist band or wearing the watch on the opposite wrist. The tightness of the band and the positioning of the watch on the wrist can affect the contact between the sensors and the skin, which in turn can impact the accuracy of the heart rate measurements.
If you are experiencing heart rate monitoring inaccuracies, try the following:
