A 40mm white gold perpetual calendar with three-tier lugs, a rose-gilt opaline dial, and Patek Philippe’s in-line day and month display.

Introduced in 2022, the 5320G-011 is the rose-gilt opaline dial version of Patek Philippe’s Ref. 5320G perpetual calendar, a design that draws on the manufacture’s perpetual calendars of the 1940s and 1950s. The 40mm white gold case is 11.13mm thick, with hand-polished three-tier lugs, a box-type sapphire crystal, and water resistance to 30 meters. The dial pairs charcoal gray white gold applied Arabic numerals with syringe-shaped hands, both with luminescent coating, and shows the day and month in an in-line double aperture at 12 o’clock, the date by hand around the moon phase at 6 o’clock, and leap year and day/night indications in apertures. It is powered by the self-winding caliber 26-330 S Q with a 21K gold central rotor, Spiromax balance spring, and a power reserve of 35 to 45 hours, visible through the sapphire crystal case back and finished to the Patek Philippe Seal standard. This 2023 example is fitted with its original shiny chocolate brown alligator strap and white gold fold-over clasp, is supplied with box and papers, and carries a Patek Philippe warranty dated May 2023 that runs through May 2028.

Suited to a collector who wants a perpetual calendar that reads clearly at a glance and wears comfortably every day, with design cues taken from Patek Philippe’s own mid-century references.
