With Patek Philippe Extract from the Archives confirming production of the present watch with silvered dial, raised hour markers in steel and tachometer scale in 1941 and its subsequent sale on 31 May 1941.
This watch must be considered one of the most attractive examples of the celebrated reference 530 chronograph in stainless steel to be offered in public in recent years. Extremely well preserved and previously unrecorded, it is in overall very good and unspoilt condition. The case shows very little wear only and has not suffered from noteworthy polishing. In fact, its proportions remain intact, most evident to the beholders eye are the clean lines of the lugs. The dial, absolutely correct for this model and period, reveals a lovely and appealing tone of eggshell and appears to be in unrestored condition. Overall, all elements are in perfect harmony and render this legendary wristwatch a sound, collector-worthy character.
To date, only six other references 530 cased in stainless have been offered at auction or published in literature. Without exception, these watches are all proudly-cherished trophies in the world's most distinguished private watch collections.
Reference 530 was introduced to the market in 1937 and is one of Patek Philippe's rarest chronograph models. Predominantly known to be cased in either yellow or rose (pink) gold, the stainless steel version is amongst the scarce specialties amongst collectors of complicated Patek Philippe wristwatches. Whereas the gold version is known to have been in production during at least two decades until the mid 1950s, it appears that the stainless steel version was only available during a short period of time, mainly in the early 1940s. One may safely assume that at this epoch, especially during World War II and the years immediately afterwards, stainless steel was the more accessible case material - not limited to watch manufacturers and without regulations imposed by customs.
Reference 530 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. Another important element for this stainless steel version is the width between the lugs, an astounding 21.5 mm. Only a few examples of the gold reference 530 feature such impressive case proportions.
