Experience the craft of IWC in the Ingenieur (ref. IW3540-03), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in yellow gold and measuring 34.5 mm in diameter, defined by a cushion silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a white tone, framed by stick / dot hour markers, and stick hands. At its heart beats a proven engine: the 35782 caliber. Initial production year: 19871992. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
