PURPOSE:To facilitate the correction operation of the electronic watch which makes selective display in plural display modes by resetting the display to the mode before correction upon ending of the watch information correction operation by storage contents. CONSTITUTION:A display mode is selected by a switch SW1 and said mode is stored in a counter 20. A display device 16 performs display in the mode corresponding to the selection such as of the date, hour, minute, day as well as the hour, minute and second by a watch circuit 13 through a display control circuit 17 and display decoder 14. Accorrding to the operation times of a switch SW2, the mode signal is generated from the shift register of a correcction control circuit 28 and the display mode of the device 16 is changed over by a decoder 14 through the gate of the circuit 17. Next, when switches SW3, SW4 are operated, the digits and count contents of the watch circuit 13 are corrected by the circuit 28. The storage contents of the counter 20 are read out by the clear signal by the operation of the switch SW2 after the end of this operation and the display mode resets to the mode immediate before the correction. Hence, the correction operation of the electronic watch which makes selective display of the plural display modes becomes easy. |
