My eight month old GW-2000 died. The hands are parked at 12 o'clock and will not move.
Exposing to light does not help, neither does pressing the buttons. The watch has been exposed to normal daylight every day so the battery should have stayed fully charged.
Now I will see how Amazon handles warranty issues.
Replacing the battery iwould be the obvious solution but I have seen posts from people where the mechanism had to be replaced.
