Abstract
An alarm timepiece operates such that after an acoustic alarm generated at a preset alarm time has been stopped, the alarm timepiece is automatically so set as to regenerate the acoustic alarm at the next preset alarm time. The generation of the acoustic alarm is compulsorily stopped during the adjusting of time, and when the acoustic alarm is stopped by manipulating a manual switch for suspension, the acoustic alarm is regenerated after a predetermined time has elapsed. When the acoustic alarm is generated for a predetermined time without being stopped by means of a manual switch, it is automatically stopped.
