Apple watch says turn digital crown to unlock and eject water

Hi

To turn off Water Lock on your Apple Watch, which is what you are describing, keep turning the Digital Crown (the round button) until the water droplet fills the circle and your Apple Watch states Unlocked (you may also hear the speaker make sounds).

If you experience any difficulties with doing so, then it may help to turn the Digital Crown more quickly:
