ABSTRACT:
Apparatus is provided for the winding of a self-winding mechanical wrist watch during intervals when it is not worn on the wrist and would otherwise run down and stop. The apparatus comprises a detachable, padded mandrel over which the self-winding wrist watch is placed and securely held by its own strap or band. The mandrel holding the watch is attached to a revolving winding shaft driven at slow speed by a motor wherein the relationship of the watch to the winding shaft is such that the axis of rotation of the stem of the internal self-winding rotor of the watch is generally coincident with the axis of rotation of the winding shaft.
