IWC Schaffhausen welcomes back the iconic perpetual calendar back to the Portofino collection.
The elegant watch is available in two versions, one in 18-carat 5N gold and the other in stainless steel, with a case diameter of only 40 millimetres, making it the smallest perpetual calendar watch in IWC’s collections.
Both versions are powered by the IWC-manufactured 82650 calibre movement, featuring automatic Pellaton winding with ceramic components and a power reserve of 60 hours. In addition to displays for the date, weekday, and month, the calendar also features IWC’s perpetual moon phase indication, which will only deviate by one day from the orbit of Earth’s satellite in 577.5 years.
Developed in the 1980s by former head watchmaker Kurt Klaus and consisting of less than 100 ingeniously arranged parts, the Perpetual calendar is distinguished by its high level of autonomy and user-friendliness. The intelligent mechanical program recognises the different lengths of the months and automatically inserts a leap day every four years at the end of February. It will continue to run without manual interventions until 21:00 when the leap year is omitted due to an exception in the Gregorian calendar. Moreover, since all its displays are perfectly synchronised, the calendar can be advanced simply using the crown.
With the Portofino Perpetual Calendar, the iconic complication returns to the Portofino line and becomes the perfect choice for those preferring a slightly more compact and ergonomic size. With a case diameter of 40 millimetres, it is currently the smallest perpetual calendar across IWC’s collections. Both versions are fitted with blue straps made of traceable Swiss calf leather. The straps have a natural and soft finish and boast a contemporary, luxurious look.
The Portofino Perpetual Calendar is available now at IWC boutiques, authorised retail partners, or online at IWC.com.
