Ingenieur Perpetual Calendar 41 Titanium (IW344904)

The IWC Ingenieur Perpetual Calendar 41 IW344904 merges the legendary Gérald Genta-inspired design with the mechanical brilliance of the crown-operated perpetual calendar developed by Kurt Klaus. Crafted from lightweight, sandblasted Grade 5 titanium, this 41.6mm timepiece offers a technical and modern aesthetic while ensuring exceptional wearing comfort through its seamless H-link integrated bracelet. Case & Design: Features a 41.6mm diameter and 13.2mm thickness, meticulously finished with sandblasted, satin, and polished surfaces characteristic of the high-grade titanium construction. Perpetual Calendar Complication: A mechanically programmed module that tracks the date, day, month, leap year, and moon phase, requiring no manual adjustment until the year 2100. Titanium Grid Dial: Showcases a matte gray "Grid" pattern with recessed subdials and a perpetual moon phase accurate to one day every 577.5 years. In-House Movement: Powered by the IWC-manufactured 82600 calibre, which utilizes the efficient Pellaton winding system and wear-resistant ceramic components visible through a sapphire caseback. Superior Durability: Offers 100 meters (10 bar) of water resistance and features a screw-down crown, making it a robust option for daily luxury sports wear. Power Reserve: Provides a reliable 60-hour power reserve, ensuring the complications remain active even when not worn for a full weekend.
