For the first time, the famous IWC calendar complication is integrated into an IWC-manufactured movement from the 82000-calibre family. The new IWC Portugieser Perpetual Calendar 42 ref. IW3442 which has a diameter of 42 mm, displays the calendar information on three subdials. IWC is also unveiling a boutique edition of the iconic 44 mm Portugieser Perpetual Calendar in 18K Armor Gold. No other complication expresses IWC’s values quite as eloquently as the perpetual calendar developed by legendary watchmaker Kurt Klaus in the 1980s.
