Portugieser perpetual calendar 42, iw344207

This version of the Portugieser Perpetual Calendar 42 presents the popular complication on a green dial. 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 features a stainless steel case, a green dial, and rhodium-plated hands and appliqués. This timeless, elegant Portugieser is fitted with a green alligator leather strap from Santoni.
