Experience the craft of IWC in the Ingenieur (ref. 666A), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in stainless steel and measuring 36.5 mm in diameter, with a thickness of 13.2 mm, defined by a round silhouette. The caseback is closed, and the crystal is plexi, delivering water resistance to 10000 meters. The dial composition is deliberate and legible: a ivory tone, framed by mixed hour markers, and stick hands. Beneath the caseback lies dependable performance: the IWC 852 caliber. Initial production year: 19541958. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
