ABSTRACT:
A watch winder includes a watch carrier that is freely supported on a rest for ease in mounting and removing the carrier and for reversing the direction of winding by simply turning the watch carrier end-to-end. The watch carrier includes a cylinder and a watch holder insertable into the interior of the cylinder. The rest is adapted to support the cylinder in a horizontal position, and includes first and second support sections having parallel longitudinal axes spaced from each other at a distance less than the diameter of the cylinder. Each section includes a housing having rollers or other support surfaces adjacent the ends of the housing, with at least one of the rollers being driven by an electric motor to rotate the cylinder at predetermined times when the cylinder is supported on the rollers. A feature of the cylinder may be detected to stop rotation at a predetermined orientation.
