The Apple Watch apart from being one of the most popular Apple devices is also a pretty tough smartwatch. The smart wearable device by Apple comes with a water resistance of 50ATM and is designed with swimmers and water-sports enthusiasts in mind. However, to protect the internal components of the watch, Apple added a pretty nifty “Water Lock” feature, that we explained in our definitive Apple Watch icons guide. So recently, popular YouTube channel, The Slo-Mo Guys, used this feature to capture a scene of an Apple Watch ejecting water in (very) slow motion.

Now, the way the Apple Watch ejects the water inside is quite fascinating and looks pretty dope, especially in such high frames per second. According to Gav, the device’s speaker vibrates at a certain level that pushes the water out of the watch.

Now, when he observed the process in slow motion, he noticed that once the first burst of water comes out, the remaining water still stays inside as it gets sucked in by the vibrating speaker again. So, for a brief moment, the speaker lowers the level of vibration to retain the water and then again creates a burst to eject it. This happens 10 times before all the water finally gets out of the watch, according to the host.
