The IWC Ingenieur Perpetual Calendar 41 Ref. IW344903 brings together the distinctive Gérald Genta-inspired Ingenieur design with IWC’s renowned perpetual calendar developed by Kurt Klaus. Its 41.6 mm stainless steel case is paired with an elegant blue dial and matching stainless steel bracelet, creating a refined yet sporty presence on the wrist. The dial features a perpetual calendar displaying the date, day, month, leap year and perpetual moon phase, protected by convex sapphire glass with antireflective coating on both sides and secured against displacement caused by drops in air pressure. A screwed-in crown and 10 bar water resistance further enhance its everyday durability.

The watch is powered by IWC-manufactured Calibre 82600, an automatic, self-winding movement equipped with the Pellaton automatic winding system. Operating at 28,800 vibrations per hour (4 Hz), the movement comprises 309 components and 46 jewels and provides a 60-hour power reserve. The 41.6 mm stainless steel case measures 13.3 mm in height and features a synthetic sapphire crystal case back, offering a view of the finely engineered movement. With its sophisticated perpetual calendar, integrated stainless steel bracelet and iconic Ingenieur design, the IW344903 is a technically impressive luxury timepiece, with warranty coverage extendable to 8 years through the My IWC Care program.
