The perpetual calendar has long been associated as the fundamental pillars of Patek Philippe. First released in 1992, the reference 5040 had a solid long run of 15 years of production through three series and was discontinued in 2007. As part of the lineage of the complication, the reference 5040 bares the atypical design popularized in the early 20th century with its unique shape. Fitted with the finely shaped tonneau case with the equally stunning Breguet numerals, the timepiece is classic yet avant-garde compared to the usual round Calatrava-styled case. The majority of this reference was manufactured in yellow gold, with fewer pieces manufactured in other metals, further enhancing the rarity of this example in platinum.

The model was produced in 3 series with approximately 600 pieces made in platinum, the first series can be distinguished by a 77X thousands movement serial until circa 1998, the second series with 3.12 million and the final with 3.67million movement serial. Offered with its original certificate and accessories, the present specimen from the second series of the 5040 in platinum is preserved in an excellent condition. It is a great chance for connoisseurs of fine timepieces to acquire a rare and highly distinctive case shaped perpetual calendar wristwatch by Patek Philippe.
