Watch with a mechano-electric generator

Abstract

A watch including, in a case (6b), a movement (44a) and a mechano-electric generator (88) including a stator (106a, 106b, 18a, 18b) and a rotor (92), one carrying permanent magnets (18a, 18b) and the other carrying coils (14). The rotor has an annular structure and is rotationally guided by at least one ball bearing (100a), the rotor having over its entire height a free internal space (130) through which the geometric axis of rotation of the rotor moves and in which the movement is at least partially located. The watch has a barrel forming a rotor drive device that can be activated on command. The watch may also have a lighting device (64) powered by the coils. The rotor (92) may carry the coils, which are connected, via an electrical circuit with no accumulators, to the lighting device which is securely arranged on the rotor.
