Wearing the GSW-H1000

How you wear the watch on your wrist affects the accuracy of heart rate monitor values. Position the watch as described below (STEP1～3).

STEP1

With the watch fastened loosely on your wrist, place at least one finger to the right of the power button* (Figure (1)).

Figure (1)

  • If the watch covers the protruding bone of your wrist (your ulna, which is circled in the nearby figure), keep adding fingers until it doesn't anymore.
  • The location and shape of this bone differ from person to person.
  • * If you wear the watch on your right wrist, place your finger(s) to the left of the pressure sensor (left side of the watch).

STEP2

Position the watch so there is at least one finger width between it and your wrist joint when you bend your hand back (Figure (2)).

STEP3

After you determine the best wrist position, tighten the band snugly so the watch does not slide on your wrist.

  • To improve measurement accuracy, keep your arm still with the touch panel facing upwards for about the first 15 seconds immediately after the start of a heart rate measurement operation (such as when you start an Activity app measurement).

Important!

  • A band that is snugly tightened for heart rate monitoring can cause you to sweat and make it difficult for air to pass under the band, which can lead to skin irritation. During normal wear, when you do not need to monitor your heart rate, make sure the band is loose enough to allow you to insert a finger between it and your wrist.
