Patek Philippe Oversized Chronograph

About this reference

Produced between 1937 and approximately 1954, the Patek Philippe Reference 530 is a manual-wind chronograph characterized by its 36.5mm case diameter, which was significantly larger than the standard 33mm Reference 130 of the same era. It utilizes the Valjoux-based caliber 13-130. Collectors value this reference for its modern proportions, concave bezel, and long, square-edged lugs. While most examples were cased in yellow gold or steel, the 18k rose gold variant is notably rarer, with approximately 30 units estimated to exist. Secondary market prices for rose gold examples typically fall within the mid-to-high six-figure range, depending on dial configuration and condition. A notable auction result occurred in 2021 when a rose gold Reference 530 with a sector dial and retailer signature sold for over 600,000 USD. The reference was eventually succeeded by the 37mm Reference 1463, which introduced a screw-down caseback.
