Abstract
The clockwork movement comprises a crown (12) connected with at least one element of the movement through a connecting organ. It is provided with a selection device (13) that includes a blocking device (15) provided with two blocking spring blades (26, 27) cooperating with a set of teeth (28) of crown (12). This blocking device allows rotation of the crown to be blocked in a first direction, and to be permitted in a second direction, in a predetermined position of a control lever (30) selectively acting on the first or second of these spring blades (26, 27) through a sector (31). When this lever (30) is turned into a second position, rotation of the crown is permitted in the first direction but blocked in the second direction. One thus obtains a movement in which the direction of rotation of crown (12) is selected by the user by his prior action on selection device (13).
