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.
