Abstract: A watch contains a date indicator ring and a day of week indicator ring. A switching wheel is displaceable selectively into meshing engagement with the indicator rings to effect adjustment thereof. The switching wheel is actuated by a shaft which is axially displaceable between selection and working positions. In its selection position, the shaft can be rotated in either direction to selectively place the switching wheel in one of two preliminary locations corresponding to a date ring adjustment location and a day of week ring adjustment position. By then axially displacing the shaft to its working position, the switching wheel is displaced to a final location to effect the previously selected mode of adjustment. Such adjustment is effected by rotating the shaft in either direction to rotate the respective indicator ring in either direction.

Abstract: A battery operated watch includes an actuator mechanism adapted to actuating indicator hands of the watch. The actuating mechanism includes a gear train adapted to drive indicator hands, a motor for driving the gear train, and an electronic block unit. The electronic block unit includes an oscillator and electronic circuit for operating the motor. A mechanism plate and bridge are provided. A carrier plate of insulative material is disposed between the mechanism plate and bridge. The carrier plate has pockets, including indentations, bores and openings, for receiving and retaining in position at least some components of the actuating mechanism. Means is provided for securing the mechanism plate, bridge, and carrier plate together, including a plurality of pillars extending between the mechanism plate and the bridge.

Abstract: A clock module for use with a separate power source comprises an electrical operating assembly contained within a rod-shaped housing. The operating assembly includes a digital recorder and an adjusting member therefor, a time keeping oscillator, integrated electrical circuitry and an electrical contact. The housing, preferably in the form of a circular cylinder, includes a longitudinal side portion and opposite end portions. The digital recorder is situated along the side portion of the housing. The electrical contact is situated at one end portion of the housing. The adjusting member is situated at the longitudinal side portion of the housing or at the other end portion of the housing.

Abstract: A watch of the watertight type has a housing including a downwardly apertured housing portion for transmitting sound. A diaphragm is attached to the housing in a manner effecting a watertight seal. The diaphragm is capable of flexure toward and away from the apertured housing portion. A piezo electric buzzer element is secured internally of the diaphragm and is responsive to electrical excitation for producing a buzzing sound. An electrical circuit is connected to the piezo element for electrically exciting the piezo element. A safety mechanism is provided for preventing an excessive amount of flexure of the diaphragm in response to pressure acting thereon. A first safety element is secured to the diaphragm. A second safety element is secured to the housing. The first safety element is movable, with the diaphragm, relative to the second safety element in an inward direction away from the apertured housing portion.

Abstract: A watch includes a housing including an apertured sound transmitting housing portion. A diaphragm is carried by the housing. A piezo electric element is carried by one surface of the diaphragm and is oscillatable in response to electrical excitation. Excitation circuitry is connected between the piezo electrical element and a power source of a watch in producing an excitation signal to oscillate the piezo electric element. The diaphragm comprises an electrically insulative material. The excitation circuit is carried by the one surface of the diaphragm, thereby eliminating the need for additional components to carry the excitation circuit.
