Still love my watch after a year of ownership, but ran into my first technical glitch w/ it this evening. I went to plug it into the computer (fully charged) and it wasn't registering w/ the USB port I plugged it into, so went to a different one. The watch went completely blank & looked dead.
Turns out this is a pretty common problem. My watch is now working again after completing the following steps & I didn't lose any data:
1. Hold the light button in for more than 30 seconds. You will see no response, hear no beeps, nothing. This doesn't mean it is not working.
2. Let go of the light button and the do a normal reset by holding the light button in for 3-5 seconds.
The watch should turn on.
Hope this is helpful to anyone who may have had the same issue!
