This time, the patent describes a strap with a quick-release mechanism and a hole for the camera.

It should work like this: you can take a photo or video directly from your wrist through a hole in the strap or quickly remove the watch (the strap will remain on your wrist) and continue shooting with the watch in your hand.

The camera in the watch is a controversial thing. No matter how the watch glows while recording a video, it can still be recognized as a spy device. And this is a potential ban on sale in some countries. A small battery will drain even faster, which is also a significant minus.
People who take photos on the iPad look strange, but what will Apple Watch owners who record videos from the watch look like then?
