Abstract (en)
[origin: WO2015144423A1] The invention relates to a control system for a rotating member of a timepiece, including a control member for actuating said rotating member, and a transmission device between said control member and said rotating member. The control system is characterised in that the gear device is a hybrid gear device including a first element which can move about a first axis of rotation (10) and is provided with a drive roller (25) made of an elastomer material, and a second element (31) which can move about a second axis of rotation (30) and is provided with a toothed gearing (32). The drive roller (25) engages with the toothed gearing (32) by means of friction.
