I think some of the parts might need to be replaced. My watch generally works well from 12am to 10:40pm. However, once it hits 10:40pm and the date mechanism starts to move (i.e., when the date starts to change), the minute/hour hands stop. I know the watch is still working because the second hand continues to move. Once I adjust the time past 12am (such that the date moves on to the number), the watch will work well again. Not sure if any parts need to be changed in order to fix this problem, so I'm concerned whether an independent watchmaker would be able to obtain original Omega parts.
