Abstract

835,357. Watches. PIQUEREZ, E. Feb. 11, 1958 [Feb. 14, 1957], No. 4397/58. Class 139. In a self-winding watch the rotor 8a, Fig. 1, is connected by arms 8b to a hub 8c disposed on a stub shaft 9 extending centrally from the case bottom 1. The hub 8c is toothed at 10 to form the first gear of the winding train. Rollers 12 are mounted on radial pins and located in peripheral notches 11. The rollers ride in the groove defined by the case bottom and the movement supporting ring 6.
