  • Patent number: 4074513
    Abstract: A circuit for an electronic timepiece which utilizes only one push button to adjust the contents of the minutes, hours, and date counters of the display circuitry is provided. The circuit utilizes an input circuit and associated timer for generating activating and intervention signals at selected points in time in response to depressions of the push button, a cyclical activation circuit rendered operative in response to the concurrent presence of activating and intervention signals for sequentially energizing intervention circuits connected to respective counters, and an intervention connection for coupling intervention signals from the input circuit directly to energized intervention circuits which cause an adjustment in the contents of a respective counter.
