Principle

The principle of the drainage function is to play sounds of different frequencies through the speaker, and use the sound wave vibration to shake the water out of the watch. The speaker hole is also used as a drainage hole.

The Apple Watch will work repeatedly when draining water. If slow-motion photography is not used, the Apple Watch will look like a drop of water is sprayed out.
