CAL. 89630

With its movable lugs and perpetual calendar, the stainless steel Da Vinci Perpetual Calendar Chronograph represents the best of 30 years of Da Vinci. The celestial body remains stationary on the dark blue "night sky", while the disc of the moon phases under the dial takes on the function of the "earth shadow", indicating whether the moon is waning or rising. Thanks to the manufacture caliber 89630, the perpetual calendar works with extraordinary precision: in 577.5 years the indication will shift only one day from the actual duration of the lunar cycle. The chronograph hour and chronograph minute hands are integrated into the internal "12 o'clock" counter, allowing the chronograph times to be read as a second hour. Thanks to the flyback function, the watch also allows you to immediately cancel, without intermediate stop, the current chronograph measurement and start a new one.
