Not worn for a couple of days due to vacation. Then when returned I had to reset the time and wind it (as expected). Nothing unusual noticed then, but the next day found my clock quit a bit off time. Then reset the clock again and found later that day the clock not working at all. The noticed that when I moved the clock sideways it started again, just for a few minutes. Also pulled the crown. This seemed to work for half a day, but later stopped again.
