Abstract

PURPOSE:To enable the display of year difference with one oscillator as a wrist watch oscillator, by taking the values of l/t and w/t within a specific range where (l) is the length of the oscillator and (w) is the width and (t) is the thickness, in an AT-cut quarty oscillator. CONSTITUTION:Taking the length of the oscillator as (l), width as (w) and thickness as (t), in a rectangular type AT-cut quarty oscillator, the relations of 6.0<=l/ t<=14.5 and 2.1<=w/t<=2.8 are obtained. Thus, the display of year difference can be made by using one oscillator as oscillator for wrist watch.
