Constantly moving or barely moving during sleep

Wearing the watch only while asleep and taking it off immediately after awaking

Nightly Recharge™ can be used when the conditions below are satisfied.

Heart rate measurement is set to [ON] or [ACTIVITY & NIGHT TIME ON], enabling continuous heart rate measurement.

Using Heart Rate Measurement

With [ACTIVITY & NIGHT TIME ON], sleep measurement starts from the time set for NIGHT TIME. For the NIGHT TIME time setting, specify your normal sleep time (bedtime and wake-up time).

The watch is firmly attached to your wrist when you go to bed.

At least three sleep measurements in the past 28 days (one of which was the night before)

To improve sleep analysis accuracy, it may take about one to two hours after you wake up for measurement results to be displayed on the watch.
