BULOVA Precisionist 96B257 is from the Precisionist Collection. Featuring Bulova’s proprietary Precisionist accuracy, this advanced chronograph offers 1/1,000-second precision over a twelve-hour time frame, with accuracy to within seconds a year. In stainless steel with curved crystal, multiple-layer black carbon fiber, blue, silver and black dial, chronograph measurement of hours, minutes, seconds, 1/10-seconds, 1/100-seconds and 1/1,000-seconds, yellow continuously sweeping second hand, luminous hour and minute hands, luminous markers, tachymeter, calendar, screw-back case, screw-down crown, double-press fold-over clasp with safety lock, and water resistance to 300 meters.
Providing an extraordinary level of timing accuracy, the Bulova Precisionist Chronograph is the only chronograph to combine stopwatch timing to 1/1,000-second with Bulova’s exclusive Precisionist-class torsional resonator movement, proven in laboratory testing to be one of the world’s most accurate.
Easy and logical to read, each style features four subdials to display the cumulative time at a single glance, with individual measurements on the combined 1/10- and 1/100-second counter, as well as the hour and minute dials, dual-duty floating second hand, and a distinctive 1/1,000-second track with retrograde indicator.
At the heart of the watch is the Bulova Precisionist-class torsional resonator movement, custom-engineered to provide accuracy to within seconds a year using a three-prong quartz crystal that creates a vibration frequency of 262.144 kHz, the highest of any watch in the world and far greater than that of a standard quartz crystal. In laboratory testing, the Precisionist-class movement has been shown to be three times more accurate than standard quartz. This proprietary manufactured movement, including the signature floating second hand, also offers a resistance to gravitational error that makes it superior in performance to any mechanical watch on the market.
