Da Vinci Perpetual Calendar Chronograph
Gold ,
Automatic ,
Aligator Leather Strap
With its articulated strap horns and the perpetual calendar, the Da
Vinci Perpetual Calendar Chronograph in 18-carat 5N gold 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.
