[Wear Chronos] "Your watch. Smarter." Converting any watch into a "smart" watch

It was a great idea, and worked well for about 3 months. You stick a bluetooth disc on the back of your watch, and it works to convey select notifications to you through vibration or through LEDs.

The problem is that once they have your money, the warranty is meaningless. After 3 months (it worked well for that time), the face fell apart. After confirming that this was under warranty and several long delays in response time (they asked for my shipping address 3 times, with ~2 weeks before they responded again), they stopped responding.

Watch out!
