DA VINCI PERPETUAL CALENDAR CHRONOGRAPH
With its articulated strap horns and the perpetual calendar, the Da Vinci Perpetual Calendar Chronograph in stainless steel represents the very best of over 30 years of the Da Vinci family. The moon remains still against the dark blue night sky while the moon-phase indicator disc beneath the dial acts as the earth’s shadow and imitates the waxing and waning of the moon. The perpetual calendar’s extreme precision is made possible by the in-house 89630 calibre. The moon phase display diverges by just 1 day in 577.5 years from the actual phase of the moon. The hour and minute counters are combined in a totalizer at “12 o’clock”, enabling stopped times to be read like a second time of day. Thanks to the flyback function, this watch allows ongoing chronograph time measurements to be instantly “deleted” and a new measurement started without an intermediate stop.
