A wristwatch is equipped with a case band, a bezel, and a guard. The case band has a circular upwardly directed protrusion to which a transparent dial cover is mounted, a surrounding wall portion forming between itself and the upwardly directed protrusion an arrangement groove extending along this protrusion, and open portions for bezel operation. The bezel having manual holding asperities facing the open portions is rotatably supported in the outer periphery of the upwardly directed protrusion, and arranged in the arrangement groove while forming between itself and the surrounding wall portion a gap extending along the surrounding wall portion. There is arranged in the gap the guard, which is engaged with a detachment preventing portion of the surrounding wall portion and moved in the peripheral direction of the bezel; the guard is movable between a use position where it closes the open portions and obstructs manual holding of the manual holding asperities and a retreated position where it opens the open portions to enable manual holding of the manual holding asperities. The guard is retained at the use position by a positioning means.

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.

A wristwatch includes a case body, a rotary bezel, one or more pieces of operating screws, and a holding member. The case body includes a ring-like portion 16a surrounding a cover glass and the ring-like portion is formed with a ring-like groove opened to an outer periphery thereof. The rotary bezel arranged at the case body includes a fitting portion rotatably fitted to an outer periphery of the ring-like portion and the fitting portion is formed with a guide groove opened to an inner periphery thereof and opposed to the ring-like groove. The operating screw is inserted to the groove from an outer side of the rotary bezel to be rotatably attached to the fitting portion. The holding member is connected to a front end portion of the operating screw by permitting rotation of the operating screw. By rotation of the operating screw, the holding member is made to be able to move over to a holding position arranged over the ring-like groove and the guide groove for preventing the rotary bezel from being detached and a release position of being fit into the guide groove.

To provide a portable timepiece capable of suppressing a bezel from carelessly rotating and deviating, without impairing a rotation operability of the bezel. An annular bezel is rotatably disposed around an annular protrusion part of a case band to whose inner periphery there is attached a cover glass. A gasket made of an elastic material, which makes the bezel stationary to a desirable rotated position with respect to the case band, is interposed between the bezel and the case band under a state giving a frictional force to these. A holding mechanism, which holds the bezel to a stationary state with respect to the case band and can release this holding state, is provided separately from the gasket. By this, a rotation operability of the bezel is made light by restricting the rotation of the bezel by means of the holding mechanism to thereby suppress a careless rotation of the bezel and thus by the fact that the gasket is caused not to bear a function suppressing the rotation of the bezel.

To provide a portable watch in which a crown can be held so as not to be turned carelessly utilizing engagement of screws without being restricted by a function of a watch movement, durability is improved, and a screw lock operation for the crown is light. The present invention is premised on a portable watch in which a crown, which is connected to a winding stem transmitting a turning force to a watch movement in a case band, is engaged with a male screw section of a pipe attached to the case band, whereby a crown is held so as not to be turned. The crown includes: a crown shaft that moves the winding stem in association with the crown shaft; and a crown head that turns this shaft. A turning force receiving section is provided on a peripheral part of a shaft end of a crown shaft arranged outside the pipe. A female screw section and a turning force transmission section are provided in the crown head. The female screw section is detachably engaged with the male screw section. The turning force transmission force is detachably fitted into the turning force receiving section following movement along an axial direction of the crown shaft in a state in which the engagement of both the screw sections are released.

A timepiece has a case body and a bezel rotatably and detachably connected to the case body. A ring-shaped guide groove formed in the bezel opposes a ring groove formed in the case body, and a plurality of holding members are slidable in the guide groove into and out of the ring groove to respectively prevent and permit detachment of the bezel from the case body. A plurality of operating screws are screwed into the bezel from an outer side thereof and are rotatably connected at their front end portions to respective holding members. Rotation of the operating screws in tightening and loosening directions moves the holding members into and out of the ring groove.

To provide a wristwatch capable of promoting operability of attaching and detaching an end-piece to and from a rod leg and capable of promoting handling performance in being brought to and from a storing place. A recess portion is formed at a back face of an end-piece of a strap. Through holes opposed to attaching holes of rod legs are respectively provided at side walls of the piece in a state of receiving the piece at a rod crotch between the rod leg of a case body continuous to each other. An attaching member including a fold back portion having pinching portions and capable of being elastically deformed in directions of increasing and reducing an interval therebetween and attaching shaft portions folded to bend from the two portions to be rotatably inserted into the holes is contained in a recess portion movably between a first position and a second position. A fixed shaft pinched by the portion when the member is arranged at the first position is provided at the recess portion to be shifted from a linear line connecting the through holes. The shaft portions are projected to outside of the piece by widening an interval between the portions by the shaft at the first position, and the shaft portions are immersed into the piece when the member is arranged at the second position by detaching the fold back portion from the shaft.
