Orbita, the world's largest purveyor of luxury watch winders, offers serious watch collectors a wide variety of luxury tools to help them maintain and display their cherished timepieces!
The Sempre Watch Winder from Orbita is the first and only watch-winding device that will keep any hand-wound mechanical watch fully wound when unworn! This patented design is truly unique in that it replicates the human action of finger winding a watch, by rotating the winding crown in a clockwise direction. The SEMPRE design features a mechanical finger arrangment, called a "collet", which grasps the watch's crown securely and rotates it in the same clockwise direction. Several different size collets are provided to fit any watch crown! The collet is opened by pushing in a spring-loaded plunger at the opposite end of the drive shaft; releasing the plunger closes the collet down on the crown. Just as the individual winding his or her watch senses the increasing resistance of turning the crown as the watch is being wound, the microprocessor "brain" of the Sempre winder monitors the electrical current drawn by the gear motor as it rotates.
For safety purposes, the drive system is also fitted with a mechanical slip-clutch which has been factory set to slip at a safe torque in the event of a microprocessor failure. This redundancy eliminates any possibility of stressing or breaking the mainspring of an expensive and, perhaps delicate, mechanical watch! In operation, the winder automatically turns on once every twenty-four hours. Upon actuation, the drive motor begins rotating the collet. With the collet rotating at 6 rpm, this provides a maximum of 48 crown rotations per day. However, the actual number of rotations is controlled by the current feedback circuit, whose priority is to shut down the motor based on torque rather than by running time. The Sempre Winder will also wind automatic watches! Owners of fine hand wound or automatic mechanical watches with numerous complications will find the Sempre Watch Winder ideal for keeping their watches continuously wound and "exercised." The winder is housed in an elegant maple burl veneer cabinet, and all hardware is high-quality brass or stainless steel with gold-plated finish. Powered by AC Adapter or (4) Alkaline C batteries (not included). Made in the USA.
