With Patek Philippe Extract from the Archives confirming production of the present watch with gold hour markers and tachometre scale in 1952 and its subsequent sale on 25 November 1952.
This watch is an extremely crisp example of the celebrated reference 530 chronograph in pink gold. Never before offered in public, it represents a true rarity since not even a dozen examples of pink gold references 530 are accounted for to date.
The impressive case shows only very light signs of surface wear; in fact, the lugs are full and retain their original proportions to the best extent. With time, the dial has taken a warm, ivory-coloured patina. Interestingly, it is featuring the "long signature" which is known to have been in use until around the mid 1940s. Consequently one can speculate that either Patek Philippe mounted in 1952 an earlier dial or that the present dial was fitted at a later stage upon an owner's request.
Reference 530 was introduced to the market in 1937 and is one of Patek Philippe's rarest chronograph models, the majority cased in yellow gold, few examples in pink gold or in stainless steel. This celebrated model is the larger version of the better known reference 130, Patek Philippe's classic chronograph retaining the timeless Calatrava design. However, reference 530 stands out by its impressive diameter overshadowing its smaller "sister model" by a substantial 4 mm. The yellow gold and the stainless steel models of this reference are known to have been made with two different bracelet widths between the lugs (19 mm. or 21.5 mm.). Interestingly, research shows that the pink gold examples exist only with one case type (19 mm.).
