Abstract
Time adjusting means for electronic timepiece which detects change in the generation condition of pulses generated in response to a manual operation speed and generates a predetermined number of pulses in accordance with the detection output as the time-adjusting pulses. The time adjusting means enables a rapid time adjustment of an electronic timepiece at a high speed. When the manual operation speed exceeds a predetermined speed, the time adjusting means stops the time-adjusting pulse so as to prevent erroneous operation.
