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.
