The device has a push-button stem (28) inserted into an orifice in a watchcase through a bottom end, and a button (29) mounted on a top part of the stem outside the watchcase. The top part of the stem includes an annular groove delimited by two parallel shoulders (44, 46) perpendicular to an axis of the stem. The button includes an annular base element (27) engaged in the groove so as to be held between the shoulders along axial direction and centered in bottom of the groove such that the button is free to move off-centre relative to the axis of the stem while remaining secured to the stem. The groove is formed by assembling two stem portions that are made of metal. |
