IWC watchmaker assembles the Ingenieur Perpetual Calendar 41 (Ref. IW344904) in Lightweight Titanium

Powering the Ingenieur Perpetual Calendar 41 is the IWC-manufactured 82600 caliber with Pellaton winding system and ceramic components, offering a 60-hour power reserve. The integrated perpetual calendar module, a Kurt Klaus creation, precisely manages calendar irregularities, including leap years. Its moon phase display requires adjustment only once every 577.5 years. The 41-millimeter case and integrated bracelet are crafted from lightweight grade 5 titanium, making it IWC's lightest perpetual calendar watch. The case, bezel, and bracelet links are precisely finished with sandblasting, polishing, and satin-finishing, highlighting its Gérald Genta-inspired design and monolithic profile. A matte gray "Grid" dial blends with the titanium, while Super-LumiNova® on applied markers and hands ensures clear legibility. Unveiled at Watches and Wonders Geneva, the Ingenieur Perpetual Calendar 41 (Ref. IW344904) unites IWC's comprehensive titanium machining expertise with its signature perpetual calendar complication.
