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 timepiece with a diameter of 42 millimetres has an 18-carat 5N gold case, a silver-plated dial, gold-plated hands, and 18-carat gold appliques. This timeless, elegant Portugieser is fitted with a brown alligator leather strap from Santoni.
