Abstract: To provide a timepiece in which operations for a rotation stop of a bezel and its release are easy, and reliability and a durability of the rotation stop are high. A bezel is disposed in a bezel disposition part of a case band so as to be capable of rotation-operating, and positioning parts and lock parts, which comprise plural concave-convex portions juxtaposed in a direction of the rotation, are formed in a back face of the bezel. To the case band, there is attached a clip stop mechanism (positioning means), which permits clockwise and counterclockwise rotations of the bezel by engaging with and disengaging from the positioning part, and holds the bezel in a position in which the rotation of the bezel is stopped. Between the case band and the back face of the bezel, a lock member is disposed so as to be movable in a diameter direction of the case band.

Abstract: A diver's watch includes a timepiece exterior assembly including a movement, a hand setting stem pipe, a crown for operating the movement, and a cover pipe. A locking face is formed at an outer peripheral portion of a case body provided to the timepiece exterior assembly. The hand setting stem pipe is fixed to the case body and includes a pipe side screw portion. The crown includes a crown cylinder inserted to inside of the hand setting stem pipe, and a crown head integral with the crown cylinder. The crown head is formed with a crown side screw portion attachably and detachably screwed to the pipe side screw portion, and an engaging end face brought into contact with and separated from the locking face. The cover pipe is arranged to be more proximate to the crown cylinder than the engaging end face. Thereby, the hand setting stem pipe is covered by the cover pipe and the covered state is maintained regardless of a movement in an axial direction of the crown.

Abstract: A portable timepiece has a timepiece movement and a movement interlock axle that undergoes linear movement and undergoes rotational movement to transmit a rotational force to the timepiece movement. An external operation body is operable to linearly move and rotate the movement interlock axle. A stopper member undergoes movement between a first position in which the stopper member is engaged with an engagement part of the movement interlock axle to prevent linear movement thereof and a second position in which the stopper member is not engaged with the engagement part to permit linear movement.

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.
