IWC Ingenieur 3521 Black, 1990s - Genta-Designed Sport Elegance. Engineered to Last.

The IWC Ingenieur 3521 represents the fifth generation of this legendary line — and it stands as one of the most refined. Produced between 1993 and 2001, this reference features all the signature design language you'd expect: an integrated bracelet, brushed tonneau case, and a bezel with functional porthole screws – nods to Gérald Genta’s original SL design.

The real highlight? The high-gloss black dial with applied gold indices and hands, paired with a subtle date window at 3 o’clock. It’s this balance between utilitarian engineering and luxury finish that defines the 3521. Powered by a chronometer-certified automatic movement (IWC Cal. 887/2), this piece blends performance and aesthetic precision.

Rarely seen in such honest and well-preserved condition, this 3521 is a versatile, everyday icon — whether worn with a jacket or just jeans.
