IWC Schaffhausen introduces the Ingenieur Perpetual Calendar 41 at Watches and Wonders Geneva. It marks the Swiss luxury watch manufacturer’s first stainless steel model to combine the Gérald Genta-inspired Ingenieur design with the perpetual calendar developed by Kurt Klaus. The 41-millimetre case, bezel and bracelet are elaborately finished with satin-finished and polished surfaces. On the blue dial with its characteristic “Grid” pattern, three subdials display the date, day of the week, month and perpetual moon phase. Rhodium-plated hands and metal markers filled with Super-LumiNova® ensure perfect legibility. The IWC-manufactured 82600 calibre with Pellaton winding system and ceramic components can be viewed through the sapphire glass case back.
In 1976, IWC introduced the Ingenieur SL, Reference 1832, spearheading its SL collection of luxury sports watches in stainless steel. Less than a decade later, in 1985, the now legendary perpetual calendar developed by Kurt Klaus premiered in the Da Vinci Perpetual Calendar Chronograph. Forty years later, IWC now presents the first stainless steel model to combine the emblematic Ingenieur design inspired by Gérald Genta with Kurt Klaus’ crown-operated perpetual calendar.
The Ingenieur Perpetual Calendar 41 (Ref. IW344903) features a stainless steel case with a diameter of 41 millimetres. 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 H-links of the bracelet are satin-finished with polished outer edges, while the middle links are polished. The case back ring, which encloses the sapphire glass case back, is polished.
