PURPOSE:To make it possible to prevent unnecessary operation of a pressurizing accelerator by displaying the operating state of each stage of the accelerating switch which corrects the watch in the forward and reverse directions at the speed of a desired stage. CONSTITUTION:The pressure of the pressurizing operation of the accelerating switch such as piezoelectric element is detected by a pressure detecting means 9. A gate circuit is controlled by a detected output through a quick sending speed judging circuit 10, a correction pulse control circuit 11, and the like, and the desired quick sending pulses are applied to a counter 4. The time corrction and the like are performed at the speed of the desired stage in the forward and reverse directions. At the same time, the detected output from said means 9 and the like are also applied to a display mark judging circuit 12 for the quick sending speed, and the quick sending correction speed mark corresponding to the operating state of each stage of the accelerating switch is lighted and displayed on a display 7. Therefore unnecessary operation of the pressurizing accelerator is eliminated and the unnecessary shortening of the life of the accelerating switch can be avoided. |
