Quartz watches like the new Citizen Calibre 0100 use the vibrations of their quartz crystals to keep time but external factors like gravity and temperature can affect the quartz oscillator which leads to deviations in timekeeping.
Creating the world’s most accurate watch means eliminating deviations. The seconds hand does not do a typical “jump” either, a special LIGA fabricated gear prevents this “backlash” and allows the hand to rest accurately over each second markerĪs with atomic timekeeping, precision in quartz timekeeping also involves managing the various environmental factors that might otherwise disturb a perfect movement. The brass second hand, a rarity in quartz watches due to its weight and incrementally increased power drain on the motor is used here because the artisans at Citizen wanted the hand to not only reach the periphery of the dial but also be “bent to point towards the seconds indexes
