Abstract
An electronic timepiece comprises an oscillator, a frequency divider for frequency dividing the output signal of the oscillator to generate 100 Hz output pulse signals, time count circuits having a plurality of counters cascade-connected to count the output pulse signals of the frequency divider, a decoder circuit for decoding the output signal of the time count circuits to generate a display signal and a display device for displaying data corresponding to the output display signal of the decoder circuit, in which a stopwatch display mode and a normal time display mode may be selected by the operation of a switch. The electronic timepiece further includes a control circuit connected between the decoder circuit and display device and adapted to inhibit normal time display data from being supplied to the display device in response to the operation of the switch which sets the electronic timepiece into the stopwatch display mode.
