A Post-War Masterpiece — Oversized Elegance with rare Bambé lugs

This IWC from 1948 is a rare blend of mid-century charm and modern proportions. Cased in solid 18k yellow gold and measuring an impressive 36mm — unusually large for the era — it’s a dress watch that feels perfectly relevant today.

What truly sets this piece apart is the beautifully stepped Calatrava-style case, enhanced by sculptural bombé lugs. Inside beats the revered Calibre 89 — one of IWC’s most legendary and reliable hand-wound movements.

Its golden dial, untouched and naturally aged with a gentle patina, pairs effortlessly with the warmth of the case. Classic, rare, and timelessly elegant, this is a standout piece for the discerning collector — one that bridges the past and present with quiet confidence.
