Abstract

PURPOSE:To provide a high-frequency crystal wrist watch, in which input, output and power source terminals of an integrated circuit are connected to other unit through a protecting circuit made of diodes and resistances arranged on other silicone substrate, whereby it is prevented that static electricity be directly applied on input, output and power source terminals of SOS circuit.
