The IWC's first secular perpetual calendar boasts a platinum case with a diameter of 44.4 mm and a height of 14.9 mm, offering a refined and durable design. Its features include small hacking seconds, Pellaton automatic winding, and a power reserve display with an impressive 7 days power reserve. The rotor with an 18-carat gold medallion adds a touch of luxury. The perpetual calendar accounts for leap year exceptions over a 400-year period, displaying the date, day, month, and year in four digits, along with an eternal moon phase. With a water resistance of 5.0 bar and double box-glass sapphire crystals with anti-reflective coating on both sides, this timepiece combines technical precision with elegant aesthetics.
