<p>An electronic timepiece comprises a time standard oscillator, at least first, secondary and additional time counting means for counting time signals derived from said oscillator, means for controlling the additional time counting means to operate as chronograph time counting means, a common display, and means, operable at will and comprising a plurality of selecting gate circuits each controllable to select, as its output, one of a plurality of inputs, one from each of the time counting means for selecting the count in any one of said time counting means for display by said common display. Preferably, each of said time counting means comprises a seconds counter, a minutes counter and a 24 hour counter and each selecting gate circuit comprises a plurality of sets of transmission gates each set being connected to receive BCD bit outputs from the respective counters, each in one of the time counting means, and means for selectively rendering said sets conductive, one at a time to transmit the input signals thereto to output terminals.</p> |
