Patek Philippe 5496P Perpetual Calendar Retrograde

The Patek Philippe Calatrava reference 5496 distinguishes itself within the Calatrava line by incorporating a retrograde perpetual calendar complication. This reference combines the classic aesthetic of the Calatrava with a sophisticated horological function, presenting the date on a retrograde scale that sweeps back to the beginning of the month. It represents a more complex offering compared to time-only Calatrava models, appealing to collectors who appreciate both traditional design and mechanical ingenuity.

This timepiece features a 39.5mm platinum case, housing the self-winding Caliber 324 S QR movement. The movement provides a power reserve of 48 hours and is visible through a sapphire crystal case back, with an interchangeable solid platinum back also provided. The dial is champagne in color, complemented by rose gold applied numeral date markers and other applied gold markers, all protected by a sapphire crystal.

For collectors, the 5496 offers a blend of Patek Philippe's enduring design language and its expertise in grand complications. Its retrograde perpetual calendar function, combined with the precious metal case, positions it as a significant piece for those seeking a technically advanced yet understated watch. The inclusion of two case backs and a platinum deployant clasp further enhances its appeal.

The Patek Philippe Reference 5059 is a perpetual calendar wristwatch featuring a retrograde date display. It is notable for its officer's style case, which includes a hinged dust cover over the sapphire case back, a design element that harks back to historical pocket watches and early wristwatches. This reference was part of Patek Philippe's offerings that showcased complex calendar mechanisms without additional grand complications such as minute repeaters or tourbillons, positioning it as a sophisticated yet focused horological instrument.

This particular reference is housed in an 18k yellow gold case measuring 36mm in diameter. The case features a polished finish and the distinctive hinged back. Powering the watch is the self-winding caliber 315 S QR, a movement known for its reliability and the integration of the perpetual calendar with retrograde date. The watch is fitted with a sapphire crystal on both the front and the display back, offering a view of the finely finished movement.

For collectors, the Reference 5059 represents a significant example of Patek Philippe's perpetual calendar tradition, particularly due to its officer's case design. This feature distinguishes it from other perpetual calendar models of its era that typically featured solid or standard display backs. The retrograde date function adds a visual dynamic to the dial, appealing to those who appreciate mechanical ingenuity and classic design cues in a complicated wristwatch.
