IWC Schaffhausen Portugieser Perpetual Calendar 42.4 mm Blue Dial 18k 5N Gold Blue Leather Strap IW344205

IWC’s perpetual calendar, developed by Kurt Klaus in the 1980s, automatically recognizes the different lengths of the months and the leap years and can easily be adjusted via a single crown. Now, for the first time, the complication is integrated into a movement from the 82000-calibre family. The Portugieser Perpetual Calendar 42 displays the date, month and weekday on three subdials at "3 o'clock", "6 o'clock" and "9 o'clock". It also features indications for the moon phase and the leap year. With the help of ceramic components, the IWC-manufactured 82650 calibre’s Pellaton winding system builds up a power reserve of 60 hours. This special edition with a diameter of 42 millimetres in a nautical design is available exclusively at IWC Boutiques and online at iwc.com. It has an 18-carat 5N gold case, a blue dial, gold-plated hands, and 18-carat gold appliqués. The timeless, elegant Portugieser is fitted with a blue alligator leather strap.
