ABSTRACT:
An electronic timepiece has an operating unit for switching between a time display mode and a demo display mode, a time measuring unit for measuring time, and a storing unit for storing a timing condition for switching between the time display mode and the demo display mode. A control unit outputs a time display signal representing time measured by the time measuring unit when the operating unit switches to the time display mode, outputs a demo display signal when the operating unit switches to the demo display mode, and outputs the demo display signal after outputting the time display signal for a preselected period of time when the time measured by the time measuring unit satisfies the timing condition stored by the storing unit.
