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 or receptacle. By applying a force, such as pressure upon the viewing window the pusher and thus the contact can be actuated.

Timepiece

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 any angular position around the watch axis. The spring arm permanently presses its end against the disk. During the normal movement run, the spring arm end moves along an insulated area of the disk unit it comes in contact with the radial segment of the disk and closes the switch, thereby initiating the sound generator.
