Since the Apple Watch is 50m water resistant since Series 2, it is not only resistant to sweat and rain, but can also be installed when swimming or surfing. The reason why such an Apple Watch is highly waterproof is that it can drain water from the speaker and microphone unit well. When performing such a drainage motion, the video of the speaker part in slow motion is released by YouTube channel The Slow Mo Guys, attracting attention.
This video was shot at 1,000 to 2,000 fps in slow motion using the Phantom Flex4K, a high-speed 4K camera. To immerse the Apple Watch in water, tap the water droplet icon in the red part of the control center and select the waterproof lock. It was soaked in water and then shot in slow motion with a camera.
The product used for the shoot seems to be Apple Watch Series 4 or 5. It is structurally unavoidable for water to enter the part for sounding 8×1mm in the speaker part located on the side of the main body. To unlock the waterproof, you need to unlock the screen by rotating the digital crown located on the side of the body. Turning the digital crown drains the water inside the Apple Watch. This vibrates the inside of the speaker and drains water from the inside.
