A device designed to automatically rotate an automatic, self-winding wristwatch when it is not being worn. This rotation mimics the natural motion of the wrist, preventing the watch’s mainspring from winding down. If left unwound, an automatic timepiece will stop, potentially requiring resetting of the time, date, and other complications. Some are simple units designed for a single timepiece, while others can accommodate multiple watches.
The primary function of such an apparatus is to maintain the watch’s accuracy and readiness for use. By keeping the mainspring wound, it eliminates the need to manually reset the watch each time it is worn. This is particularly beneficial for timepieces with intricate complications, such as perpetual calendars, which can be cumbersome to reset. Historically, these devices were developed as a solution for individuals with extensive collections of automatic watches, ensuring that each timepiece remains operational and properly calibrated.
