Abstract

PURPOSE: To simplify the time difference correction mechanism, by enabling to correct the hour and minute hand only by means of crown without stopping second hand.
CONSTITUTION: In case of hour and minute correction, when the winding stem 7 is pulled out, the clutch wheel 33 and the setting wheel 31 are geared to turn the cannon pinion having friction slip and hour wheel via the minute wheel, allowing to make possible the correction of hour and minute hands. In this case, the step motor 4 continues rotations as usually. When the second hand is desired to be corrected accurately, winding stem 7 is pulled out and pushed again in a shorter time than the set time of the timer 37, then the gate 41 outputs H level, a part of the frequency division circuit 2 and the drive circuit 3 are reset to stop the output to the motor. Further, when the winding stem 7 is pushed in matching with the desired time, the gate 41 is at L level and the step motor 4 again starts the operation.
