PURPOSE:To facilitate manufacture while increasing the degree of freedom of design by decreasing the number of switches, by performing display mode switching, correction mode switching and correction, etc., by one unit of a switch by selecting a gate through switch operation. CONSTITUTION:When an input switch 4 is pushed for longer than a prescribed second period, a mode counter 2 is activated by the output of a pulse-width selecting circuit 1 to set a correction mode for the time, etc., and the output of the counter 2 is outputted from a corresponding gate of a selection gate 3 to perform correction. When the switch 4 is pushed for shorter than the prescribed second period, on the other hand, a prescribed pulse from the circuit 1 is applied directly to the gate 3 to select a prescribed gate, and consequently display mode switching is performed to perform the switching of display contents such as the time, date, day of the week, etc. Thus, mode switching, the execution of the modes, etc., are controlled by using one unit of the switch to decrease the number of external operating members, so that the degree of freedom of the design of a full electronic timepiece is increased while its manufacture is facilitated. |
