This IWC Ingenieur ref. 666AD stands as one of the most iconic technical wristwatches of the 1960s, designed for engineers and professionals working in magnetically charged environments. Introduced as IWC’s direct response to the Rolex Milgauss, the Ingenieur features an inner soft iron cage that shields the movement from magnetic interference, all while retaining a timelessly elegant aesthetic.
The silver sunburst dial, paired with raised applied markers, dauphine hands, and a date window at 3 o’clock, embodies the perfect balance between functionality and classic charm. At its core beats the renowned Caliber 8531, equipped with IWC’s proprietary Pellaton winding system — a benchmark of durability and technical excellence.
The 36.5 mm Staybrite stainless steel case with screw-down back ensures robustness and resistance, while the original Gay Frères bracelet — specially made for IWC and signed on the clasp — adds significant collectible value.
A superb example of IWC’s engineering prowess, this watch is an essential piece for discerning collectors seeking elegance, technical sophistication, and vintage appeal.
Case: the case features a classic round shape, crafted from Staybrite stainless steel — a highly corrosion-resistant alloy used by IWC during this period. It is fitted with a screw-down caseback and includes an internal soft iron shield, giving the watch its antimagnetic capabilities. The 36.5 mm diameter was considered substantial in its era and remains highly wearable today.
Dial: the silver sunburst dial showcases a brushed circular finish, enhancing the play of light across its surface. Applied baton and double markers, dauphine hands, and a peripheral minute track complete the functional yet elegant layout. The date aperture at 3 o’clock is neatly integrated, and the inscriptions “International Watch Co. Schaffhausen” and “Ingenieur” reinforce the authenticity and originality of the dial.
Movement: at the heart of this watch is the automatic Caliber 8531, a historical cornerstone of IWC’s movement development. Featuring the patented Pellaton winding system, this caliber is renowned for its durability and efficient winding mechanism. The central rotor, fine finishing, and visible engravings all highlight the craftsmanship and technical ingenuity behind this piece.
