Min. ReadIWC Schaffhausen introduces the Ingenieur Perpetual Calendar 41 at Watches and Wonders Geneva, marking a significant milestone in luxury watchmaking. This model combines the Gérald Genta-inspired Ingenieur design with Kurt Klaus' renowned perpetual calendar mechanism. The 41mm stainless steel case, bezel, and bracelet are meticulously finished with satin and polished surfaces, creating a stunning visual contrast. The blue dial, featuring the signature "Grid" pattern, showcases three subdials displaying the date, day of the week, month, and perpetual moon phase. The rhodium-plated hands and Super-LumiNova®-filled markers ensure excellent legibility. The watch is powered by the IWC-manufactured 82600 calibre with a Pellaton winding system, visible through the sapphire glass case back.
The Ingenieur Perpetual Calendar 41 (Ref. IW344903) boasts a stainless steel case with a 41mm diameter. The design proportions have been carefully adjusted to house the perpetual calendar movement while maintaining ergonomic comfort. The H-link bracelet, integrated seamlessly into the case, features a butterfly clasp for secure wearability. The bezel, a key element of Gérald Genta's design, is attached to the case with five functional screws, contributing to the watch’s sculptural and timeless aesthetic. Both the case and bracelet offer a combination of satin-finished and polished surfaces, adding depth and refinement to the overall design.
The dial is another highlight of the Ingenieur Perpetual Calendar 41. Its intricate “Grid” structure is created through a complex manufacturing process, with small lines and squares reflecting light in a captivating manner. The three subdials, which display the calendar information, are given a sunray finish and azurage accents, offering a beautiful interplay of textures and light. The moon phase display, visible in the subdial at 6 o’clock, is rendered with a detailed azurage finish. Rhodium-plated hands and metal markers filled with Super-LumiNova® ensure legibility in all lighting conditions.
The Ingenieur Perpetual Calendar 41’s perpetual calendar features a high-precision moon phase, which will only deviate by one day after 577.5 years, thanks to a sophisticated gear train. The calendar subdials at 3, 6, and 9 o’clock display the date, month, and day of the week, with a small leap year indicator at 9 o’clock. The leap year indicator counts down to the next leap year, ensuring the calendar inserts a 29th day in February when necessary.
The watch is powered by the IWC-manufactured 82600 calibre, featuring the automatic Pellaton winding system. This system uses the movements of the oscillating mass to generate energy for the mainspring, offering a power reserve of 60 hours. The movement is equipped with high-quality components made from zirconium oxide ceramic, which are incredibly durable and resistant to wear. The rotor bearing is crafted from white ceramic, while the automatic wheel and clicks are made from black ceramic, ensuring smooth operation and longevity. The movement is visible through the sapphire glass case back, where the finishing includes circular graining, Geneva stripes, and blued screws.
