The lavish, diamond-set version of the reference 5270, the reference 5271 can be considered an impressive exercise in restrained overstatement. Patek Philippe revealed the new reference 5271 at Baselworld in 2014, which featured a black dial and most notably a bezel set with 80 baguette-cut diamonds weighing approximately 4.84 carats. With remarkable attention to details, the setting is present on the lugs as well and even the deployment clasp is adorned with baguette-cut diamonds.
While maintaining the undeniable wrist presence of a gem-set timepiece, the black dial and superbly elegant overall architecture make this watch one of the very few diamond-set pieces which manages not to strike the ineffable balance between flamboyant and elegant, a feat very few makers beyond Patek Philippe have mastered.
The reference 5270 and its diamond-set sibling reference 5271 are notably a proud heir to Patek Philippe's prestigious perpetual calendar chronographs starting with reference 1518, 2499, 3970 (and gem-set 3990) and finally the reference 5970 (and gem-set 5971). This model brought 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 is offered in virtually untouched condition. As its Certificate of Origin states, it was originally sold about 3 years (February 2021) ago, and an analysis of the case confirms that it has scarcely - if ever - been worn. The full set of original accessories - additional solid case back, setting pin, wallet, product literature, presentation box - making this the perfect example for the completionism collector.
