Our iPhones and iPads are protected by Activation Lock, a security feature that prevents thieves from wiping and using a stolen Apple device with a new account, but the recently released Apple Watch has no similar security feature.



From MacRumors:

As pointed out by iDownloadBlog in a detailed post on the security of the Apple Watch, there is nothing that stops a lost or stolen Apple Watch from being wiped and paired with a new iPhone. The Apple Watch has a passcode option that requires a sequence of numbers to be entered every time it's removed from a wrist, but the passcode protects only data. The passcode is also easily bypassed with a reset. Pressing down on the side button of the Apple Watch brings up the power down options and a force press on this screen brings up an option to Erase All content and Settings. Erasing the Apple Watch in this manner erases the passcode and allows the Apple Watch to be paired with a new device, with no hint of the original owner's information available.
