The IWC Ingenieur Automatic 40 modernizes Gérald Genta’s legendary 1976 Ingenieur SL with refined ergonomics and striking visual depth. Crafted in stainless steel with a versatile 40 mm diameter and a slim 10.7 mm profile, it features the collection’s signature round bezel secured by five functional polygonal screws. Its standout feature is the distinctive aqua dial, stamped with a complex grid pattern that shifts from deep teal to vibrant emerald under changing light. Rhodium-plated hands and appliques filled with Super-LumiNova ensure legibility in low light. Driven by the in-house IWC-manufactured 32111 calibre, the watch provides a robust 120-hour power reserve. A soft-iron inner case shields the movement from magnetic fields, while a screw-down crown ensures 10 bar (100 m) water resistance. Completed by a seamlessly integrated steel bracelet with butterfly clasp, this reference delivers a compelling balance of high-grade engineering and luxury sports style.
