I think the problem is with the position of the two hands of the watch. I lost the instruction manual and i didn't wind up the clock. For example: the normal clock have the big hand at 12 and the small hand at 6 and we say that "it's 6 o'clock" but if i put the big hand at 12, the small hand is at 6 but between 6 and 7. the hands are not set corretly. Also both hands are a little bit free and move faster sometimes.
