It’s natural to want to check the time if you wake up in the middle of the night, but do you want a bedside clock that lights up the entire room with its giant LED numbers? (Maybe it was the clock that woke you up!)
Nightstand Mode on the Apple Watch displays the time, date, battery level and the next alarm when the watch is connected to its charger and sitting on its side. The screen remains off until you tap the screen or press one of the physical buttons, then turns off after a few seconds.
To enable the feature, open the Apple Watch app on your iPhone, tap General and then turn on Nightstand Mode. Or, on the watch itself, open the Settings app, go to General > Nightstand Mode and activate the Nightstand Mode switch.
