The problem is that, if I am moving my arm just a little bit, the clocks hands tends to move around. and sometimes, it's as if they are unable to show o'clock precisely, for example when the time is 12:00 and the watch has been shaken, it can happen,that both hands can not stand vertically  together,  then maybe the small one is a little bit left of where "12 o'clock" is, and the long one is a little bit to the right.

please call me if I have described the problem clearly enough.
