Collectors of vintage Patek Philippe chronographs are most familiar with the firm’s landmark references 130, 533, 591, 1463, 530 and 1579. However, few can spontaneously name reference 1506 and many admit that they have never actually held in their hand an example of this rare gem. This shouldn’t be a surprise as scholars only know 3 examples in yellow gold and 3 in rose gold. Furthermore, it has now been 7 years since the last example of this reference has been offered at any auction, world-wide. Consequently, the offering of the present example, for the first time ever in public, is an event by itself.Reference 1506 is not only one of the rarest vintage models ever created by Patek Philippe, but also one of the largest. With a diameter of 36mm, large multi-facetted lugs some 20mm apart from each other, the overall appearance is striking and best described as prominent while sitting beautifully on its wearer’s wrist.The rose coloured dial is in excellent condition and all the signatures and scales are properly raised and free of signs of restoration. The case has very good definition to the lugs, bezel and pushers – the most exposed parts and those suffering most from unprofessional polishing.Coming from a long and very private ownership and one of the most important collections of vintage watches, this rose gold reference 1506 has the pedigree any buyer can possibly hope for and constitutes for the well-versed collector an incredibly rare opportunity.
