I bought a Casio GW3000-1AER about a week ago and in the first days all was perfect, the watch worked as it should and the synchronization also. Two nights ago something strange happened, I left my watch near the window to ensure a better synchronization and in the morning I found that it stopped at about 1 o'clock in the morning. The second hand was still moving but the minute hand and the hour hand remained frozen. After that I manually set the time and all was working again. What do you thing it's the problem ? I just cannot trust this watch if the same thing will happen again in the future. Is there any reset procedure for GW3000?
Any help it's much appreciated.
