"...…In brief, Bulova’s design takes into account temperature changes and vibration frequency of the quartz movement by adding a third prong to the quartz crystal. This design increases the total vibrations to eight times that of a standard quartz movement, with the Precisionist running at 242.144 Khz. The result is the sweeping second hand that actually ticks 16 times per second, even higher than a mechanical movement’s 8 to 10 times per second."

"…Inside all the current Precisionist watches are the Japanese made Bulova caliber P102.12 or P112.10 quartz movements. As far as I know those are the only two Precisionist movements available right now. Bulova is owned by Citizen (Japanese) at this time, but used to be US owned. The movement offers three major desirable features. First and most importantly is the accuracy. The watch is accurate to about plus/minus 10 seconds a year. That is in comparison to about 15 seconds a month for standard quartz movements. It is also comparable to much higher-end Japanese and Swiss thermocompensated quartz movements. Second, the watch has a smooth sweeping seconds hand. It is smooth like the seconds hand on a Seiko Spring Drive, and more smooth that the seconds hand on most mechanical watches. Third, it has an acceptable battery life rated at between 2-3 years per power cell.
…The P102.12 movement operates at 262,144 Hertz. That is really fast and accounts for the accuracy. In comparison, a standard quartz movement operates at 32,768 Hertz, and a mechanical movement operating at 28,800 bph is only running at 4 Hertz."
