From the Precisionist Collection with precise timing to 1/1000th of a second and continuous-sweep second hand, the Precisionist Chronograph is particularly refined. In stainless steel with silver-tone and grey finish and black dial, flat mineral glass, screw-back case, screw-down crown, and double-press fold-over buckle and safety clasp. Powered by Bulova’s unique three-prong quartz crystal Precisionist movement with a 262 kHz vibrational frequency—eight times greater than standard watches—it defines accuracy.
