The lavish, diamond-set version of the reference 5270, the reference 5271 is an impressive specimen. Patek Philippe revealed the new reference 5271 at Baselworld in 2014, which most notably featured a black dial and set with 80 baguette-cut diamonds weighing approximately 4.84 carats. At the time of launch, it replaced its predecessor, the reference 5971 which had a Lemania-based movement. An eye-catching timepiece, it most notably cased in platinum - a nod to its high jewellery roots. An an even nicer touch, even the deployant clasp is set with baguette diamonds, adding prestige to the timepiece.

The reference 5270 and its diamond-set sibling reference 5271 is notably a proud heir to Patek Philippe's prestigious perpetual calendar chronographs starting with reference 1518, 2499, 3970 and finally the reference 5970 or 5971. The present watch brings the Patek Philippe perpetual calendar chronograph into the modern era with its in-house caliber CH 29-535 PS Q, the first of its kind. Dazzling and eye-catching, it is an incredibly iconic model that showcases Patek Philippe's skill in merging gem-setting with haute horlogerie.

The present timepiece was brand new and double sealed originally. It was only unsealed on August, 16 2023 in front of Phillips' in-house counsel for the purpose of shipping the timepiece. It is furthermore accompanied by its Patek Philippe Certificate of Origin dated December 11, 2014, additional caseback, hang tag, setting pin, wallet, product literature, wallet and presentation box.
