IWC has introduced the Ingenieur Perpetual Calendar 41 at Watches and Wonders 2025 in Geneva. This marks the first time the brand combines the Gérald Genta-inspired Ingenieur design with the perpetual calendar developed by Kurt Klaus in a stainless steel model.
The Ingenieur Perpetual Calendar 41 (Ref. IW344903) features a stainless steel case with a diameter of 41,6 mm and thickness of 13,4 mm. The proportions of each case component have been reworked and adapted to accommodate the perpetual calendar movement while offering perfect ergonomics. Seamlessly integrated into the case via a middle-link attachment, the H-link bracelet with a butterfly clasp ensures high wearing comfort. The characteristic bezel, a hallmark feature of Gérald Genta’s design, is secured to the case with five functional screws. The detailed finishing further accentuates the sculptural quality and timelessness of the Ingenieur design. The case, bezel and crown protection feature a combination of satin-finished and polished surfaces.
The blue dial, featuring the distinctive “Grid” pattern, houses three subdials displaying the date, day, month, and moon phase. Rhodium-plated hands and indices filled with Super-LumiNova® ensure visibility in low light. The subdial at 6 o’clock includes a moon phase complication that remains accurate for 577.5 years. The perpetual calendar system automatically adjusts for leap years and can be set via the crown.
The Ingenieur Perpetual Calendar 41 is powered by the IWC-manufactured 82600 calibre. The automatic Pellaton winding system uses movements of the oscillating mass in both directions to efficiently convert movements on the wearer’s arm into potential energy for the mainspring, thereby building up a power reserve of 60 hours. Components that are subject to high stress are made of virtually wear-free zirconium oxide ceramic, one of the hardest materials on Earth. The automatic wheel and the clicks are made of black ceramic, while the rotor bearing is made of white ceramic. The balance wheel oscillates at 28,800 vibrations per hour, ensuring accurate timekeeping. Featuring an elaborate finishing with circular graining, Geneva stripes and blued screws, the movement is visible through the sapphire glass case back.
The price of the new IWC Ingenieur Perpetual Calendar 41 is 38,000 CHF (including VAT).
With this release, IWC expands the Ingenieur lineup, integrating renowned high complication into a design that remains faithful to Genta’s original vision while adapting to modern standards.
