<p>In a watch-case (11) provided with one or a plurality of press-buttons (23) intended to actuate controllable elements movable by spring pressure and acting on a control slide (12) arranged in the case wall and sliding axially with respect to itself and useful for the elements to be actuated, they are provided to control the button, respectively the button body, at least two spaced apart guides (24, 25) pivoting on parallel planes, of which one end forms a hinge with the watch-case wall, and of which the other end forms a hinge with the button, those guides being fixedly connected; there is also provided an additional element (26) ensuring a displacement of the pressure surfaces of the button (23) parallel with the latter. Said additional element may be an other guide (26) completing the above mentioned pair of guides (24, 25) to form a parallelogram control. </p> |
