An electronic timepiece equipped with an alarm system whereby an external control member is actuated a desired number of times or for a desired time duration causing a count to be set into a first counter. Subsequently, when an alarm is generated, an identical count value must be set into a second counter by actuating an external control member for the same number of times or for an appropriate time duration in order to shut off the alarm. Possibility of the user shutting off the alarm signal and then falling asleep again is thus greatly reduced. A snooze switch control function can also be easily incorporated.

Electronic timepiece

An electronic timepiece having an acoustic hour information function in which a photosensitive switch mechanism essentially comprising a photosensitive element is provided to detect a quantity of light below a predetermined value in the surrounding environment where the timepiece is placed and control the acoustic hour information function of the timepiece depending upon the detected result.
