I take mine off unless I'm traveling. Back in my misspent youth I had a calibrated autowind chronograph, lay it face up and gain about ten seconds over night, face down, lose about ten seconds, stem up/down gain/lose five seconds, 12 o'clock up very little gain/loss. They were adjusted that way by the maker so after a few weeks of checking it you knew which way to place it to cancel out the day's error. Problem was you had to send it to the maker's rep for cleaning (about every two years) no local watch makers would take the time to do it right. Could keep time well within a minute a month if you worked at it. Even had a little wallet chart to track its error if you had access to a radio time signal.
