IWC Ref. R604 – Gold Dress Watch with Caliber 89 (1964)
This elegant IWC Ref. R604 from 1964 perfectly captures the understated sophistication for which International Watch Co. is known. Crafted in 18k yellow gold, the watch features a clean silver-white dial with slim stick indexes and matching hands, creating a timeless and beautifully balanced appearance.
Its softly downturned lugs and oversized 36 mm case — unusually large for a dress watch of the era — give it a strong wrist presence that feels remarkably modern even today.
Inside beats the legendary IWC Cal. 89, one of the finest manually wound movements ever produced, renowned for its reliability, precision, and elegant construction. A classic mid-century IWC that combines vintage charm with everyday wearability.
