Abstract
PURPOSE:To enable the time accuracy within an annual difference of several seconds to be obtained by adding the signal having at least one or more different compensation characteristics other than the basic compensation pulse groups to the logic circuits forming the compensation pulse groups. CONSTITUTION:In the crystal watch which takes AND between the signal having the frequency crresponding to the absolute value of the difference of the oscillation frequencies between the two main and sub-crystal oscilators 01, 02 having the frequency temperature characteristics approximated by quadratic functions and further the output signal of a preset timer circuit 42 synchronized with the signal divided therefrom to form a series of basic compensation pulse groups and compensates the frequency temperature characteristics of the main crystal oscillator 01 by applying these to the output signal of the main crystal oscillator 01, the logic circuits forming the compensation pulse groups are so constituted that signal having at least one or more different compensation characteristics other than the baic compensation pulse groups is added.
