PURPOSE:To regulate time for a digital watch with preferable operating sense by generating pulses of number corresponding to the rotated amount of a rotary switch to correct the counted content of a predetermined counter. CONSTITUTION:When a rotary switch 8 is rotated, it generates pulses of number corresponding to the rotated amount of the switch 8 to alternatively set and reset an RS type flip-flop FF11 to apply one-minute or one-hour pulses of the number corresponding to the rotated amount of the switch 8 through a multivibrator 12 and a switch 13 to minute or hour counter 3 or 4 connected to minute or hour indicators 5 and 6, respectively to correct the counted content of the counter 3 or 4. With such a configuration it can regulate the digital watch with preferable operating sense by the rotating operation. |
