Abstract

PURPOSE: To obtain quick correcting feeling and self-correcting feeling of a digital electronic watch similar to the correction of an analog watch by varying the self- moving speed of the display according to the rotary speed of a frequency divider switch at time correcting time to vary the correcting amount by the rotary amount.
CONSTITUTION: Every time a rotary switch S2 repeates ON and OFF operations, a counter 11 is reset through a chattering preventive circuit 7 and an OR gate 9, and the counter 11 starts counting of clock signals CLb simultaneously to thereby write the time interval of the ON-OFF-ON operations of the switch at selected address by the counter 13 in a memory 15. The reading of the memory 15 is controlled by a counter 18, and a selector 20 selects information regarding the ON- OFF interval of a switch S2 to thereby quick feed the clocks Clc-1Wm. The time can be corrected by selecting the number of the frequency dividers of a counter 23.
