Abstract
The invention concerns a push-piece control device for a watch comprising a case (10) provided with a middle (12), an arbor (16) integral with a crown (20) and mounted pivoting in the middle (12) and a push-piece (18) mounted sliding and coaxial to the arbor (16). The invention is characterized in that it further comprises a lever (32) mounted pivoting on said case (10) by one of its ends (32a), mobile in a plane substantially parallel to the watch plane, including, in its median part (32b), a contact point designed to co-operate with said push-piece (18) and, at its other end (32c), a concave control portion.
