Apple Watch’s has sensors on the back.

This means the device can tell when it’s being worn and when it has been taken off.

When you first put the watch on, you must enter a code. When the watch is removed from your wrist, the watch locks itself and can’t be used for payments unless the code is entered again.

Pretty simple right? Unless the thief chops your hand off, of course, but that’s a different story.

So buyer be warned as they say!
