Hey r/Watchexchange! IWC Ingenieur Automatic Chronometer Ref. 3521 The IWC Ingenieur Ref. 3521 is a sought-after model that blends iconic Gerald Genta design with modern horological performance. Measuring 34mm in diameter, this timepiece features a sharp stainless steel case paired with an 18k yellow gold bezel, giving it a refined two-tone aesthetic. The crisp white dial is understated yet elegant, with applied gold hour markers and hands, and a date window at 3 o’clock for practical daily wear. At the heart of the watch beats the IWC Caliber 887/2, based on the ultra-thin Jaeger-LeCoultre 889 movement, which is COSC-certified for chronometer accuracy—a rare and prestigious feature in IWC’s catalog.
