See How the Apple Watch Ejects Water in Slow Motion

The Apple Watch, which can be worn while swimming and doing other water-based activities, has a neat feature that's designed to use the speakers to eject water, protecting the internal components.


The Slow Mo Guys, known for science and technology-related videos that take advantage of slow-motion cameras, today took a look at how the Apple Watch water ejecting feature works, featuring it up close and slowed down.

As the video demonstrates, the Apple Watch goes through 10 cycles where the speakers vibrate to push out all of the water inside. In slow motion, the force with which the water is expelled can be seen, and it's an impressive visual.

When planning to use the Apple Watch in the water or when a swimming workout is initiated, users can set a water lock feature that's designed to prevent the display from activating when exposed to water droplets.

When turned off, the feature, enabled through the Control Center, triggers the function that expels water from the speaker when the Digital Crown of the Apple Watch is turned. The water lock and water ejecting features are available on the Apple Watch Series 2 and later.

How is this interesting? Its been around since AWS3. It's odd that only now a video is featuring this on macrumors site. It should've been available since the S0 as someone else mentioned though.

Well they were the first to think about doing it. And the Series 0 didn't have this feature.
No need to be upset about the video, it was cool indeed.

Gavin's deep dive into the Apple Watch water ejection system is fascinating.

And his deep dive into a bathtub was just as impressive!

Only Apple can come up with something so insanely ingenious.
