To provide a wrist-portable equipment that may prevent malfunction of an internal rotational ring. There is provided a wrist-portable equipment including: a case, an internal rotational ring to be used as a display member for rotating independently and separately from a gear train of circumferential divisional hour/minute/second within the above-described case, an operating shaft that may be pushed into and drawn out of the above-described case, a clutch for transmitting the rotation of the above-described operating shaft to the above-described internal rotational ring and for releasing the transmission of the rotation by pushing in the above-described operating shaft; and a stem provided at one end portion of the above-described operating shaft and disposed on a side surface portion of the above-described case.

To provide a watch in which, in case where a screw lock function has decreased, a part exchange around a crown is made possible while ensuring a waterproofness. To an outside winding stem pipe having a bridge portion and brazed to a case band there is passed an inside winding stem pipe having a male screw portion directed to an outside of the case band and a convex portion colliding against the bridge portion so as to be capable of being put in or out, the pipe is locked to the pipe by a lock means provided over both of the winging stem pipes, and the pipe is interposed between an attaching ring detachably meshing with the pipe and the convex portion, thereby positioning the pipe with respect to the former pipe in an axial direction. A crown is detachably meshed with the male screw portion of the pipe. It is characterized in that an inside waterproof gasket is interposed between the pipe and a crown cylinder portion, of the crown, inserted into the pipe, and an outside waterproof gasket is interposed between the outside and inside pipes.

A wrist-portable apparatus has a case housing a rotational display member and an operational shaft for undergoing rotational movement and sliding movement relative to the case so that the operational shaft may be axially displaced between a pushed-in position, in which the operational shaft is pushed into the case, and a drawn-out position, in which the operational shaft is drawn out from the case. A clutch assembly transmits rotational movement of the operational shaft to the display member to rotate the display member when the operational shaft is displaced to the drawn-out position and releases the transmission of the rotational movement of the operational shaft to the display member when the operational shaft is displaced to the pushed-in position. A manual control stem is integrally connected to an end of the operational shaft and is disposed on a side surface portion of the case for controlling rotation of the operational shaft and displacement of the operational shaft to the pushed-in and drawn-out positions.

A rotating-type bezel apparatus has a case body and a bezel rotatably mounted on the case body and having alternately spaced recesses and projections. A first member is mounted on the case body and has an end portion elastically engageable with surface portions of the recesses and projections of the bezel to impart a click feel to the bezel during rotational movement thereof. A second member is movably mounted on the case body for movement between a first position and a second position. In the first position, the second member engages the first member to prevent a release of an elastic engagement between the front end portion of the main body of the first member and the surface portions of one recess and the two projections on either side of the one recess of the bezel. In the second position, the second member does not engage the first member and thereby permits the release of the elastic ingagement between the front end portion of the main body of the second member and the surface portions of the one recess and the two projections on either side of the one recess of the bezel.

A portable timepiece has a pipe extending from a case and a winding stem for transmitting a rotational force to a timepiece movement in the case. A crown is connected to the winding stem for rotational movement therewith and for detachable engagement with an outer periphery of a male threaded section of the pipe to prevent unintentional rotation of the crown. The crown has a crown shaft for rotating the winding stem, a crown head having a female threaded section for threaded engagement with the male threaded section and mounted for undergoing rotation to rotate the crown shaft in a state in which the engagement between the male and female screw sections is released. A clutch couples together the crown shaft and the crown head to prevent rotation of the crown shaft in a state in which the male and female threaded sections are engaged with one another and couples the crown shaft and the crown head to allow the crown shaft to rotate during rotation of the crown head in a state in which the male and female threaded sections are not engaged with one another.

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; a crown head that turns the crown shaft in a state in which the engagement is released; and clutch. The crown head has a female screw section that is detachably engaged with the male screw section. The clutch couples the crown shaft and the crown head so as to prevent the turn of the crown shaft in a state in which the engagement is completed, and couples the crown shaft and the crown head so as to make it possible to turn the crown shaft following the crown head in a state in which the engagement is released.

A wrist-wearable electronic apparatus has a case and a band connected to the case for attaching the electronic apparatus to a wearer's wrist. A flexible expansion chamber is provided on the wrist side of the case or the band, and a pump communicates with the interior of the expansion chamber for supplying air thereto to inflate the expansion chamber so that it can be maintained in close contact with the wearer's wrist. The pump has a pair of push-in portions on opposed lateral sides of the case or band adjacent the wrist side thereof so that the wearer can apply sideways directed forces to actuate the push-in portions to supply air to the expansion chamber. A discharge valve communicates with the interior of the expansion chamber for discharging air therefrom. The pump may be rotatably mounted to enable the wearer to position the push-in portions at desired positions to facilitate actuation thereof by the wearer.
