ABSTRACT:
Winding crown for a timepiece, said crown (32) including an uncoupling mechanism (1) comprising a rigid drive ring (4, 400) secured to the crown (32) and cooperating with at least one elastically deformable element (2; 200) secured to a pipe (12) to one end of which a winding stem is secured, the rigid ring (4; 400) driving the deformable elastic element (2; 200) in at least one rotational direction until the resistant torque opposed by said elastic element (2; 200) exceeds a threshold value beyond which said elastic element (2; 200) is deformed so as to interrupt the drive connection thereof with the rigid ring (4; 400), the elastically deformable element (2; 200) therefore having means for temporary coupling said element to said rigid drive ring (4; 400), the crown (32)) being characterized in that the elastically deformable element (2; 200) includes means for centring said element relative to the rigid drive ring (4; 400).
