A watch, especially a wristwatch, with adjustable time-dependent signal transmission and an indicator adjustable to random time positions of the watch dial for determining or fixing the signal time point. An electronically operated storage is provided which has individual storage elements each associated with a predetermined time position. Upon actuation of a switch the time position indicated by the indicator can be extinguishably registered at the relevent or corresponding storage element and ...

An alarm wrist watch incorporating a watch band, a watch casing and an electro-acoustical signal transmitter which can be activated by the watch movement or clockwork at pre-selected signalling times. The electro-acoustical signal transmitter is arranged at a part of the watch band removed from the watch case.

In a housing there is accommodated a quartz-controlled watchwork together with a display covered by a viewing or sight window and with at least one contact serving to accomplish control functions. The contact can be actuated by the base or floor of the housing, for instance by an actuator in the form of a pusher which piercingly extends through the housing base or floor. To facilitate actuation of the contact the housing is mounted to be displaceable, against the action of a spring, in a casing ...

The sounds of the alarm are produced by a membrane exposed to the atmosphere and against which strikes a vibrating blade located in a recess provided in the outer surface of a piece which constitutes a section of an envelope tightly surrounding the watch movement, the latter being located in a recess provided in the inner surface of said piece.

The alarm device of the watch comprises a switch controlled by the watch movement for switching on the alarm at the desired time. This switch is mounted directly on the watch movement coaxially to the watch hands. The remaining elements of the alarm device (buzzer, battery, switch, interrupter, setting mechanism) are all together carried by a supporting member arranged for receiving the watch movement and holding it firmly within the watch case.

The operation at the desired time of the sound generator associated with the timepiece having a quartz watch movement is initiated by the closure of a switch. One contact pole of that switch is formed at the end of a helicoidal spring arm made integral with a plane thin washer fixed to the hour wheel of the watch movement. The other contact pole of the switch is formed on a disk coaxially rotatable around the movement axis and has the shape of a radial segment. That disc can manually be set in a...
