Abstract

PURPOSE:To enable to count correctly up to minimized unit of theoretical counting for watches, by using the crystal oscillator for the oscillation source of electronic watches. CONSTITUTION:The crystal oscillator is used as the oscillation source of watches. The oscillator forms the crystal plate in which the cut out azimuth to the crystal axis rotated around by +5 deg. by taking the X axis as rotation axis, into diapason type. Further, if the diapason type curved oscillator is the crystal plate having the same cut out azimuth, the resonant frequency is determined with the ratio of the length 9 toward Y axis to the width 10 of Z axis. Accordingly, the reciprocal in minimum unit of the counting of watches is determined so that the length 9 toward Y axis and the width 10 toward Z axis can be accurately measured theoretically to the minimum unit of the watch the same as the case with frequency.
