| Sounds the same as what Dell call a flea power drain.

| would need them to service the watch.
|
| This is a 1st generation watch though, and their nearly $200
| service fee seemed excessive. So I just let the watch sit around
| for a week or so. Then I tried charging it again and it worked!
|
| What must have happened was that it was either a really bad
| software issue of some kind or an intermittent hardware issue
| that prevented the watch from working or rebooting, but when the
| power gave completely out and it was recharged, everything was
| set back into a functioning state.
|
| The watch has worked perfectly (or as well as it ever did) for
| weeks now.
