Abstract

PURPOSE:To make small the oscillator in size and to increase the spurious performance, by using the crystal plate of a given size as an oscillator, in wrist watch. CONSTITUTION:The azimuth of the normal of a crystal plate (phi, theta) is cut off in the range of phi=-85 deg. to -95 deg. and theta=30 deg. to 45 deg. and the side surface is of bevel 4 type or convex type, then the length l2 of the part having constant width remained and the length le of the exciting electrode 2 to the length l1 of the oscillator 1 are l2/l1<=1/2, le/l1<=1/2, and when the width is taken as W, 1/25<= W/l1<=1/4 is in existence, and when the plate thickness is taken as t, the length is t/W<=0.6. Shuch as oscillator is used.
