How to Use alarms and timers
Set an alarm
Open the Alarms app on your Watch. Previous alarms can be reused by flicking a switch. Or, tap Add Alarm. Use the crown to snooze an alarm, or the side button to stop it. Watch alarms can’t be set to repeat daily.
Set a timer
Open the Timer app. You can quickly tap a pre-created length of time, or scroll down to Custom and select that, then choose a length of time. If you use the Siri watch face, any time remaining will show in it.
You can ask Siri to set timers and alarms. Say “Hey Siri, set a timer for 10 minutes” or “set an alarm at 8am.” If Siri mishears, tap the switch on an alarm to turn it off, or a timer’s length to open the app and change it.
