IWC Da Vinci Perpetual Calendar

About this reference

The IWC Da Vinci Perpetual Calendar reference 3750 was produced from 1985 through the early 2000s. Collectors value this reference for introducing the caliber 7906, a movement based on the Valjoux 7750 featuring a perpetual calendar module designed by Kurt Klaus. This module allows all calendar indications, including the four-digit year display and moon phase, to be synchronized and adjusted solely via the crown. The 39mm 18k yellow gold case is characterized by its stepped bezel and hinged lugs. On the secondary market, this reference typically trades between $10,000 and $15,000 depending on condition and the presence of original accessories. A notable production detail is the inclusion of a sealed glass vial containing a century slide for the year display, intended for installation in the year 2200 to ensure the watch remains functional for five centuries.
