Ok, so I kept the watch on motion for about 15 minutes last night from about 12:07am. I checked the time this morning and the hands stopped moving at 7:43am. To me, that's pretty good. I would have to think a full days wear would have it powered to hold for several hours longer.
Guy's, thanks for all the input. I AM NOT A WATCH GUY. I'll be as informative as I can.
Mike, I have a parts trade program that may interest you.
