Abstract
903,753. Watches. ETA. A.G. EBAUCHERSFABRIK. May 5, 1961 [May 6, 1960], No. 16459/61. Class 139. The relationship between intermeshing winding trains of a combined manual and selfwinding watch is improved by a device, comprising a manual winding pinion 1 geared to the ratchet-wheel 3 through a crown-wheel 2, and a self-winding pinion 4 meshing with the ratchet-wheel, the teeth of the crown-wheel having a circular pitch which is a multiple of the circular pitch of the ratchet-wheel teeth. The crown-wheel may be formed initially with teeth corresponding in circular pitch to those of the ratchet wheel, the unwanted teeth, e.g. every alternate tooth, being then removed so as to form notches 2a increasing the depth of tooth, these notches having substantially parallel sides 2b flanking the teeth so formed.
