IWC Da Vinci Perpetual Calendar

IWC's most stylistically restless line, and one it has largely stepped back from, so today it's mostly a pre-owned story. The Da Vinci has worn several faces: the round 1980s Perpetual Calendar that made Kurt Klaus's famous mechanical calendar a legend, the curved tonneau cases of the 2000s, and the round, lug-heavy relaunch of 2017. What ties them together is ambition, this is where IWC put its inventive calendar and chronograph work in a dressier package. The one to know is the Da Vinci Perpetual Calendar, a genuine horological milestone. Current production has thinned right out, so if a specific Da Vinci speaks to you, the secondary market is where you'll find it.
