Patent ID: 7540655

Claim:
A setting device for a watch, comprising: a crown body having an inner portion; a coupling operable to couple, in at least one of an axially adjustable manner and with a rotating manner, the inner portion of the crown body to a mechanism within the watch; a crown sleeve fixed to a case of the watch and at least partly enveloping the inner portion of the crown body and the coupling, the crown body being mounted within the crown sleeve in both an axially adjustable manner and a rotatable manner; and an elastic element, positioned against the crown body so as to bias the crown body in an axial direction with respect to the crown sleeve, wherein the elastic element is operable to automatically effect a change in the axial position of the crown body with respect to the crown sleeve in response to a change in an external pressure applied to an outer portion of the crown body, such that an inner portion of the crown body may be coupled and decoupled to the mechanism solely in response to said external pressure, and wherein the coupling is operable i) to couple a rotation of the crown body to the mechanism when the crown body is rotated in a first direction, and ii) not to couple the rotation of the crown body to the mechanism when the crown body is rotated in a second direction opposite said first direction.
