THE PORTUGIESER PERPETUAL CALENDAR 42 STORY 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 a stainless steel case, a silver-plated dial, and gold-plated hands and appliqu_s. This timeless, elegant Portugieser is fitted with a black alligator leather strap from Santoni.
