![]() ![]() Thousands of small “windows” dot the dial to allow sunlight into the solar cells. Super TitaniumTM with Duratect Caliber 0100 with 6 months on full charge (about 8 months in Power Save mode). White gold Citizen Caliber 0100 is priced US$16,800 Unlike mechanical timekeeping which measures its time by vibrational frequency in a range of 2 to 5 Hz (and even 18 Hz today), ultra-high precision quartz watches measure theirs in excess of the standard 32,000 Hz (Bulova precisionist movements vibrate at 262,144 Hz, we will get back to the Calibre 0100 in a moment) and so, to achieve an accuracy of ± 1 second per year (that’s right, not month), Citizen had to look to eliminating or managing those external factors. ![]() 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
