Portofino Perpetual Calendar Automatic Watch for Men

At 40 millimetres, the Portofino Perpetual Calendar is an elegant and sophisticated timepiece. This version features a stainless steel case, a silver-plated dial, and gold-plated hands and appliques. IWC's legendary perpetual calendar, engineered by Kurt Klaus, automatically recognizes the different lengths of the months and leap years, requiring no adjustment until 2100. The calendar information is displayed in three subdials, and a moon phase display shows the moon against a star-studded night sky. The IWC-manufactured 82650 calibre automatic movement, visible through the sapphire glass back, features a Pellaton winding system and a 60-hour power reserve.
