The extreme accuracy is cut at a special angle to achieve the precise oscillation rate and aged to assure the most stable oscillations over a long period of time. cro • A fixed voltage current passes through the crystal which is the result of the highly stable oscillations of accuracy. Now SEIKO Quartz watches are changing the world's standard of the quartz crystal.
