ABSTRACT:
Even if a lock member impeding a crown from being excessively pull-moved is carelessly moved, its recovery is easy, and a function for stopping a careless movement of the crown, by the lock member, is maintained for a long period. A wristwatch possesses a case band, a crown, a protector, and a lock mechanism. A winding stem pipe is attached to the case band. The crown has a crown head having non connection relation with the winding stem pipe. This crown is supported to the winding stem pipe so as to be movable in an axial direction of this pipe. The protector is attached to the case band while facing on an end face of the crown head so as to allow an operation of this crown head. The lock mechanism is provided operably in the protector. The lock mechanism has a screw body, and a lock member linearly moving in a direction contacted with and separated from the end face of the crown head by a rotation of the screw body. The lock mechanism moves the lock member between a lock position allowing an operation in which the crown is pull-moved and a lock release position restricting the operation in which the crown is pull-moved.
