IWC Cal. 401 Dress Watch R1205, 1964 - Timeless Proportions. Mid-Century Elegance. Modern Appeal.

This classic IWC dress watch from 1964 blends understated refinement with enduring presence. Cased in 18k yellow gold and featuring beautifully straight lugs, it wears larger than its 33mm diameter suggests, lending a modern impression to its mid-century origins.

The silver dial, untouched and flawless, is paired with gold leaf hands and applied indices — a combination that echoes the aesthetics of contemporary minimalism while staying deeply rooted in vintage charm. Inside beats the Caliber 401, one of IWC’s reliable hand-wound movements, ticking confidently with +5 sec/day accuracy.

Whether you're building a serious collection or seeking a daily dress companion with quiet luxury — this piece delivers.
