ABSTRACT:
An electronic timepiece, used as a pager watch, has a speaker for emitting an alarm sound at a preset time and also for reproducing an external call signal intercepted by a receiver for incoming electromagnetic waves. The receiver may be maintained normally inactive, being periodically activated for short time intervals under the control of a frequency divider in the output of a crystal oscillator serving to drive an electro-optical display. Sensors responsive to abnormal ambient conditions, e.g. temperature or blood pressure of the wearer, may also operate the speaker.
