Abstract

PURPOSE:To improve accuracy and lower cost by so making temperature characteristics of the oscillation frequency of a crystal vibrator that the temperature becomes 0 when the mean temperature within the watch body during wearing is 23 deg.C, and performing temperature correction with electronic circuits.
