Replica IWC Da Vinci Perpetual Calendar Chronograph Watches Description
The first Da Vinci wristwatches were a pretty radical change from everything the CBI had done before. The barrel-shaped and round-bottomed pillars are extremely dressed, and the level of complexity is something very new to the IWC. The major topic of discussion was the perpetual calendar mechanism; The first, and indeed the first perpetual calendar in which every indication could be established by the crown, with the day, date, month and year and phase of the moon, everything changes in synchrony with each other, So Da Vinci the ancestor of all perpetual calendars modern synchronized mechanisms.
The Da Vinci has become the vehicle for other experiences as well; Ceramic models without metal coated came out in 1986, and Da Vinci versions equipped with whirlpools were also introduced. The perpetual calendar of the IW392101 Ref. IW392101 is in many ways a return to the more formal aspect of articulated pods 1985 cylindrical models were changed to a more contemporary style, however (though still articulated) and the chronograph and crown pushbuttons have been Updated too.
The most significant change, however, is in motion. The original Chronographs of Da Vinci perpetual calendar used a 7750 (the highly modified Valjoux perpetual calendar plate designed by Kurt Klaus was used on another of the same period clock, including Novocento Long Interruption Calendar with an F. JLC watches or roughing).
However, the new models use the perpetual calendar chronograph movement of the CBI – caliber 89630. The configuration is very similar to that used by the CBI Kurt Klaus Edition for, and is a classic: a high precision lunar phase (specific one Gap in a day in 577.5 years) and a four-digit year display, which can show until the year 2299.
At that time, a watchmaker will replace the two figures figures of the century with a new one for the period 2300- 2599. The movement of the flyback chronograph 89360, which was the basis of the caliber 89630, a coaxial totalizing minute and hour at 12:00, and the CBI has combined this function with lunar phase disc at 12.00 hours (as used In perpetual automatic internal CBI Caliber 52610 calendar).
