Summary: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 ).
