ABSTRACT:
An electronic timepiece, wherein an oscillator drives a frequency divider and the output of the frequency divider controls via a driver circuit a display device.
A short-circuit between an output of the driver circuit and a pole of the power supply causes a selector inserted between two of the stages of the frequency divider to feed to the stage following the selector, not as normally, the frequency delivered by the preceeding stage but a higher frequency. This serves for speeding up circuit testing.
