When Water Lock is turned on, your Apple Watch won't respond to touch on its display. This prevents accidental input while you're in water. When you turn off Water Lock, your watch will eject any water that remains in its speaker.
How to turn on Water Lock
- To open Control Centre, press the side button (for watchOS 9 or earlier, touch and hold the bottom of the screen, then swipe up). You can open Control Centre from any screen.
- Tap the Water Lock button
. The Water Lock icon 
will appear at the top of the watch face.
Water Lock will turn on automatically when you start a water-based workout, such as swimming or surfing. It will also turn on automatically when you start a scuba dive with your Apple Watch Ultra.
Double tap is not available when Water Lock is turned on.
How to turn off Water Lock and eject water
With Water Lock turned on, press and hold* the Digital Crown on the side of your Apple Watch until the display says Unlocked. A series of tones will play to clear any water that remains in the speaker. After this, you can use your display as usual.
* If your Apple Watch has watchOS 8 or earlier, rotate the Digital Crown instead of pressing it.
