Abstract (en)
[origin: EP2058714A1] The crown has a disengaging mechanism (1) with a rigid driving ring (4) integrated to the crown and cooperating with an elastically deformable element (2) e.g. spring. The ring drives the element in a rotation direction until resisting torque opposed by the element exceeds a threshold value. The element is deformed to interrupt its driving connection with the ring, when the torque exceeds the threshold value. The element has coupling pieces (20) temporarily coupling the element with the ring, and arms (14, 16, 18) centering the element with respect to the ring.
