From the Icon Collection with precise timing to 1/1000th of a second and continuous-sweep second hand, the chronograph is particularly refined. With stainless steel case and all-over black plating, black carbon fiber dial, curved mineral glass, eight hand calendar chronograph, and fold over closure. 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.
