User Manual

NOTE: If you go to bed before your bedtime and also wake up after your bedtime, your

watch does not count that as a sleep session. You should set your bedtime according to the

earliest you may go to bed and the latest you may wake up.

Once you have enabled sleep tracking, you can also set your sleep target. A typical adult

needs between 7 and 9 hours of sleep per day, though your ideal amount of sleep may vary

from the norms.

Sleep trends

When you wake up, you are greeted with a summary of your sleep. The summary includes, for

example, the total duration of your sleep, as well as the estimated time you were awake

(moving around) and the time you were in deep sleep (no movement).

In addition to the sleep summary, you can follow your overall sleep trend with the sleep

insight. From the watch face, press the lower right button until you see the SLEEP display. The

ﬁrst view shows your last sleep compared to your sleep target.

While in the sleep display, you can swipe left to see your average sleep over the last seven

days. Swipe up to see your actual sleeping hours for the last seven days.

While in the average sleep display you can swipe left to see a graph over your average HR

values for the last seven days.

Swipe up to see the actual HR values for the last seven days.

NOTE: From the SLEEP display, you can keep the middle button pressed to access

sleep tracking settings.

NOTE: All sleep measurements are based on movement only, so they are estimates that

may not

reﬂect your actual sleep habits.

Measuring heart rate while sleeping

If you wear your watch during the night, you can get additional feedback on your heart rate

while sleeping. To keep the optical heart rate on during the night, ensure that Daily HR is

enabled (see 3.1.2. Daily HR).

Automatic Do Not Disturb mode

You can use the auto Do Not Disturb setting to automatically enable Do Not Disturb mode

while you sleep.
