Abstract: A control system for a rotating element of a timepiece including a control element for actuating the rotating element and a transmission device between the control element and the rotating element. In the control system a gearing device includes a hybrid gearing device including a first element, which is movable around a first rotation axis and including a drive runner made from elastomeric material, and a second element, which is movable around a second rotation axis and including a rolling tooth system. The drive runner cooperates with the rolling tooth system by friction.

Abstract: A watch is delimited by a case formed of a back cover and of a middle part. A timepiece movement is disposed in a casing ring housed inside the watch case. The watch also includes a dial disposed on top of the casing ring and held by a fixing ring. The fixing ring has an S-shaped cross-section. An upper branch of the fixing ring is supported on the dial and a lower branch of the fixing ring is supported on the casing ring. The lower branch of the fixing ring is clamped between the middle part and the casing ring, so as to grip the dial between the upper branch of the fixing ring and the casing ring.

Abstract: The push-button control device for a watch includes a push-button stem (28) inserted via a bottom end into an orifice (22, 23) of a watchcase and a button (29) mounted on a top part (28a) of the stem (28) outside the watchcase. The stem can slide axially between a rest position and an active position against a return member (35) to control at least one function of the watch. The control device is characterized in that the top part (28a) of the stem includes an annular groove delimited by two parallel shoulders (44, 46) perpendicular to the axis of the stem, and in that the button (29) includes an annular base (27) that is engaged in the groove so as to be held between the two shoulders (44, 46) in the axial direction and centred with some play by the bottom of the groove such that the button (29) is free to move off-centre relative to the axis of the stem (28) while remaining secured thereto.
