How to turn off Water Lock and eject water
Press and hold* the Digital Crown on the side of your Apple Watch until the display says Unlocked. A series of tones plays to clear any water that remains in the speaker, and then you can use your display as usual.
* If your Apple Watch has watchOS 8 or earlier, rotate the Digital Crown instead of pressing it.
