IWC Cal. 89 Bombé 18k Rose 1955

IWC Cal. 89 – Oversized Elegance with Rare Bombé Lugs (1955)

This exceptional IWC from 1955 is a beautiful blend of mid-century elegance and modern proportions. Crafted in 18k rose gold and measuring an impressive 36 mm—remarkably large for a dress watch of its era—it wears with a presence that feels just as contemporary today as it did seventy years ago.

What truly distinguishes this piece is its beautifully stepped Calatrava-style case, complemented by sculptural Bombé lugs that flow gracefully from the case and give the watch a unique architectural character. Combined with the untouched champagne dial, which has developed a gentle, even patina over the decades, the result is a watch of remarkable warmth and refinement.

Inside beats the legendary IWC Cal. 89, widely regarded as one of the finest manually wound movements ever produced by the manufacture. Renowned for its exceptional reliability, robust construction, and elegant finishing, it remains one of the great classics of post-war Swiss watchmaking.

Beautifully preserved and professionally serviced, this IWC is a rare opportunity to own one of the manufacture's most desirable dress watches—combining oversized proportions, timeless design, and one of the finest hand-wound movements of the twentieth century.
