Abstract

PURPOSE: To provide an electronic watch, in which a crystal oscillator and an oscillating circuit are piled on a base plate so that the line connecting them may be shortened to the minimum so as to prevent the floating capacity from increasing and to obtain a stable oscillation frequency.
