Apple Watch: Anti-Theft

Leander Kahney, Cult of Mac:

Thanks to sensors on the Apple Watch’s back, 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.

Guess you can’t wear the Apple Watch loose?
