Abstract: A timepiece has a valve that discharges gas from an exterior assembly and includes a casing, a valve member that moves from a closed position to an open position in accordance with an inner pressure of the assembly, an exhaust button movable into the casing, a first spring urging the button and valve member away from each other, and a second spring urging the button toward the exterior of the assembly. When an inner pressure of the assembly is greater than a force of the first spring, the valve member is moved to the open position and a portion of the gas accumulates between the valve member and the button. When the button is moved into the casing, the accumulated gas is discharged to the exterior of the assembly by which the valve member is maintained at the closed position by the spring force of the first spring.

Abstract: A portable watch is equipped with a watch exterior member, a crown, a crown lock button, and an urging member. In a case band with which the exterior member is equipped, there are formed a crown mounting hole and a member mounting portion communicating with this hole and vertically perpendicular thereto. The crown is arranged in the hole. The crown has a crown shaft portion passed through the hole and a crown head portion continuous therewith. The crown shaft is provided with a lock groove continuous in the peripheral direction. The lock button accommodated in the mounting portion has a button head portion (operation end portion) protruding from the mounting portion. The button is movable between a lock position where it is engaged with the groove to constrain the crown and a lock canceling position where it is detached from the groove to cancel the constraint of the crown, and is arranged at the lock canceling position through a one-touch operation of the button head portion.

Abstract: There is provided a wristwatch 1 in which a degassing valve with an exhaust button is attached to a timepiece exterior assembly, and in which the gas in the exterior assembly is allowed to escape to the exterior through pushing-in of the button. The valve is equipped with a valve casing providing communication between the interior and exterior of the exterior assembly, a valve member accommodated in the valve casing and moved from a closed position to an open position when the interior of the exterior assembly is not less than a predetermined pressure, the button accommodated in the valve casing so as to allow pushing-in, a first coil spring urging the button and the valve member away from each other, and a second coil spring urging the button toward the exterior of the exterior assembly.

Abstract: A portable apparatus has a push button mounted on a casing for operating a contact inside the casing. The push button is axially slidable in a pipe fixed in a through-hole extending through the casing. A coil spring encircles the pipe and is interposed between a flange of the pipe and a head of the push button to urge the push button outwardly. A packing ring for sealing the space between the pipe and push button is attached to either the pipe or the push button in the region where the coil spring encircles the pipe. Since the coil spring overlaps the packing ring, the axial length of the pipe and push button can be shortened to reduce the size of the casing.

Abstract: To provide a wristwatch in which an attachment/detachment operation of an end piece of a band in regard to bow feet of a case band is easy. A concave part is formed in a back face of an end piece of a band and, under a state in which the piece is received in a bow crotch between adjoining bow feet, through-holes facing on attachment holes of the bow feet are respectively provided in side walls of the piece. The rotation member is rotatably held in the concave part. From one end to the other end, one pair of cam holes of shapes in which distances in regard to a center of a rotation member become gradually small are point-symmetrically provided in the rotation member, and a rotation operation groove is provided between these cam holes. Connection end parts of one pair of connection members forming L-shapes are passed through the through-holes, and cam follower end parts of the connection members are inserted into the cam holes.

Abstract: To provide a timepiece in which a position alignment of a bezel is easy, and a position-aligned bezel can be made so as not to be carelessly rotated. A portable timepiece possesses a case band, an annular bezel, a click member, a coil spring, and a lock member. In the case band, there are provided an annular bezel disposition groove opening upward and to an outer periphery face, and an accommodation hole extending in a vertical direction while opening to a bottom face of this groove. Bezel is disposed, while being fitted to the disposition groove, so as to be rotatable in both directions of a clockwise direction and a counterclockwise direction in regard to the case band. A click member engaging with and disengaging from an engagement part comprising plural irregularities juxtaposed in a rotation direction in a back face of the bezel facing on the bottom face is accommodated in the accommodation hole so as to be vertically movable.

Abstract: A wristwatch (portable apparatus) is provided with a wristwatch exterior (apparatus exterior) having a through hole, a pipe, a push button, a coil spring, and a packing in a ring-like shape. The pipe is formed by providing an outwardly arranged cylinder portion having a spring receiving face integrally with an inserting cylinder portion. The pipe is fixed to the timepiece exterior by inserting the inserting cylinder portion to the through hole, and the outwardly arranged cylinder portion is arranged at an outer portion of the timepiece exterior. The push button includes a drawout preventing member attached to a shaft portion movably penetrating the pipe for preventing the shaft portion from being drawn out from the pipe, and an operating head provided at the shaft portion. The coil spring for urging the push button to an outer side of the timepiece exterior is interposed by the operating head and the spring receiving face.

Abstract: A switching mechanism for a timepiece comprising a base plate having first and second bores extending therethrough and intersecting, a circuit board having a surface opposite the second bore and having stationary contacts mounted on the surface opposite the second bore, and a contact member disposed within the second bore and dimensioned to slide therein. The contact member has a transverse bore extending therethrough and alignable with the first bore through the base plate, and the contact member has a conductive lower end portion extending from the base plate and terminating at a contact surface for contacting to electrically connect the stationary contacts on the circuit board. A spring biases the contact member downwardly to a lowered position with the contact surface contacting the stationary contacts on the surface board.
