Meet IWC Ingenieur (ref. IW3505-01), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in stainless steel and measuring 34 mm in diameter, with a thickness of 8.6 mm, defined by a round silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 12000 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 375 caliber. Introduced in 19831990. 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.
