Video of the Bulova caliber P102 and Smooth Sweeping Seconds:īulova does not provide much information on the movements in their watches.The result? A reduction in the effect of temperature variation and superior accuracy. This unique construction generates 8 times more vibrations than traditional quartz. Precisionist has the highest number of vibrations (262.144kHz) of any quartz watch. Standard quartz crystals have only two prongs. The innovative Precisionist crystal has three prongs, creating a torsional resonator – the prongs not only move back and forth, but twist. Most quartz watches are accurate to within 15 seconds per month… Precisionist is accurate to within 10 seconds per year. Bulova is owned by Citizen and the P102 movement is made in Japan.
