Abstract
An alarm signalling electronic timepiece including an alarm signalling circuit which generates alarm signal at a preset hour, and a sound circuit which generates signalling sound by the alarm signal. This timepiece includes a timer counter which can memorize and subtract preset time and which can supply the alarm signal to the sound circuit after the set time elapses from the start of down count from a a time start circuit which holds the time memorized in said timer counter until the alarm signal from the alarm signalling circuit changes and which starts counting in said timer counter when the alarm signal changes, and external switches which externally switch over to work or cancel said time start circuit, whereby plural and different alarm signalling hours can be set with more simplicity.
