The tourbillon is a mechanical device that was invented to improve the precision of old-fashioned pocket watches. These devices continually rotate the escapement, balance wheel, and spring to compensate for bias due to gravity. A high-quality modern mechanical watch can achieve a precision, referred to as rate error in the horological community, of 1 s per day, while a less expensive mechanical watch may attain a precision of 5 s per day. To place these figures in perspective, the precision of… Expand
