Abstract
An electronic timepiece including a second counter, a minute counter, an hour counter and a date counter connected in cascade. Each of the counters develops a respective count representative of seconds, minutes, hours and date. A display is responsive to the counts developed by the respective counters for displaying time. A date-seconds selecting circuit, responsive to a control signal, selectively applies a respective one of the counts developed by the second counter and the date counter under control of the control signal for selectively displaying seconds and date. Control circuitry is operable for developing the control signal to select seconds and date display.
