Man, I'm getting confused (nothing new).
If you wear it during the day, it should keep running all night and most of the next day (minimum) without wearing it again. Lets say you wear it all of today, go out and get gassed tonight. You wake up tomorow morning and have a severe hangover. You go back to bed and sleep it off. You wake up about 2-3pm.....it should still be running.
Basically, if you wear it all day, take it off at night, put it back on the next day, take it off at night, repeat, you should never need to manually wind it. If you skip a day of wearing it, you'll probably have to wind it by the end of the day you didn't wear it. It would be odd that a watch winds ok automatically, but not manually, but I guess it could happen. I've got some that do have a short reserve. If I take it off around Midnight, it'll quit running around 3:00pm the next day if I don't wear it/wind it. The Pannies seem to have a much longer reserve then the Polexes', though, at least in my experience.
