The heart of this new Quartzmatic beats 32,768 times a second to bring you a whole new dimension in timekeeping accuracy. From the sundial, to the water clock, to the pendulum, to the balance wheel... man has never rested in his search for accurate timekeeping. And because time is money, we have become increasingly preoccupied with time keeping accuracy-to the point where today's world operates in microseconds. Yet, most of us still keep time with personal clocks and watches in which the timekeeping mechanisms are about the same as those Napoleon used. That is why the Quartz Crystal Timekeeping Breakthrough, pioneered by Westclox, is so significant. For when a quartz crystal is electronically stimulated, it can vibrate at thousands of oscillations a second, compared to 2 or 3 a second for a balance wheel, 360 a second for a tuning fork. Inside every one of these Westclox Quartzmatic watches beats a quartz crystal heart, to bring you a personal timekeeping possession-accurate within one minute a year.* Quartzmatic leading the new time technology A.
