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