I have a number of analog watches that run on button batteries. The batteries run down, get replaced, and then I have to reset the time and date. I remember the original instructions they all came with about setting the date outside the range of roughly 9:00 PM to 3:00 AM, but I always have a 50:50 chance of the date subsequently changing at noon instead of midnight. I've tried setting the date at all hours of the day, but nothing changes my odds. Is there some trick to ensure that the date changes at midnight after setting it?
