Abstract

PURPOSE: To measure the oscillation frequencies of a crystal oscillation type watch with high accuracy by making use of the phenomenon that the current consumption of the crystal oscillation type watch becomes pulsation flow synchronized to the vibrations of a crystal vibrator and detecting the pulsation flow of the current consumption.
