Sleep Monitor - Oppo WATCH User Manual

5.3 Sleep monitor

If you wear your watch during bedtime, the watch will have your sleep report
ready to be viewed when you wake up the next day. (Note that OPPO Watch
can only track sleeping from 8pm to 10am local time).
When you wake up, you can also open the Sleep app to view your sleep report
last night. (The watch will not send the sleep notification if you have already
viewed the sleep report on your phone).
