Apple's Activation Lock made the iPhone less desirable to thieves, since they'd also need your Apple password to use it. The Watch is supposed to be similarly unhackable, but the built-in security apparently doesn't work very well, according to a site called iDownloadBlog. It demonstrated that the passcode protection that's supposed to kick in when you take the watch off can easily be bypassed by "force touching" the power-off option, as shown in the video below. That will erase everything sans passcode, letting thieves pair your Watch with another iPhone and make it their own. Since the Watch is currently desirable and hard to get, Apple had better jump on the problem, stat.
