ABSTRACT:
An electronic timepiece including a plurality of counter circuits which together develop a count representative of time. A decoder circuit develops decimal signals representative of the counts developed by the respective counters, and a plurality of first switching circuits is operative to apply the respective counts developed by the respective counters in a timesharing mode. A plurality of second switching circuits, operating in synchronism with the first switching circuits, applies respective decimal signals, each corresponding to the count of a respective counter, to respective memory circuits for storage therein. The stored decimal signals are converted to serial binary signals by respective ones of a plurality of serial converting circuits, and the serial binary signals are applied to respective figure electrode driving circuits for developing figure electrode driving signals to drive figure electrodes of a display device having display elements each comprised of figure electrodes and separate segment electrodes. A segment electrode driving circuit intermittently drives the segment electrodes of the respective display elements in synchronism with the operation of the switching circuits to enable the respective display elements to display decimal figures corresponding to the contents of the respective counters and representative of time.
