Details: At your fingertips: The only winder for hand-wound watches. Totally unique in concept, the Sempre winder will wind, but never overwind, virtually any manually wound mechanical watch ever made. Replicating finger winding action, precision collets (mechanical fingers) grasp the watch crown and wind the watch as you would. An ingenious microprocessor control senses the increasing resistance as the mainspring is being wound and automatically stops winding when the watch approaches the fully wound state.
NOTE:*The Sempre is not recommended for watches that utilize a crown guard.
Product Dimensions: 6.8″H x 13.2″W x 10.2″L
Warranty: Your ORBITA watch winder should provide you with many, many years of trouble-free service. It comes to you complete with a two-year warranty for any defects in materials and/or workmanship.
