Reason on working of Apple Watch Water Eject System
If you've ever seen this screen on your apple watch telling you to turn the digital crown to unlock and eject water
hen you've probably wondered why the feature exists well it's called water lock and it's exclusive to the apple watch since it's designed to be used while swimming and showering
But there are some issues with constantly submerging an electronic device underwater first touch screens don't behave as expected when wet since water dissipates the electrical conduction of your finger plus the touch screen has a hard time differentiating between water droplets into your finger
So in order to prevent usability issues while wet the apple watch automatically locks the display when it detects moisture
But there's another issue caused by water and it has to do with the speakers since they're the only opening in the apple watch's exterior water can easily accumulate and cause damage especially if the watch is being submerged on a daily basis so to prevent any long term issues apple created the water eject feature
Which plays a deep oscillating tone through the speakers to force out any remaining water it does this when you rotate the digital crown telling the watch that you've finished swimming or showering now water lock usually turns on automatically
So you don't even have to think about it and you can tell when it's on by the small water drop icon at the top of the display
But in some cases you may want to enable it manually which you can do by going to control center and tapping the water drop button now even though the apple watch is water resistant it isn't waterproof so you'll want to avoid soaking it in water that's been combined with powerful soaps or solutions like dishwashing liquid or car washing soap
These powerful chemicals can deteriorate the apple watch's seals over time possibly leading to water damage although swimming in chlorine and wearing it during a quick shower is okay
