Offering a glimpse into the past, present, and future, Patek Philippe presents a new perpetual calendar for the wrist, the Ref. 5320G. Designed to stand out with a timelessly sleek design, the model features a lacquered cream dial enhanced with gold Arabic numerals, sharp-tipped luminous hands, crisply graduate seconds scales, and a slender sweep seconds hand, all encased within a box-type sapphire-crystal glass that overlaps the bezel. The perpetual calendar’s contemporary vintage-style case is augmented by a glossy chocolate brown alligator strap with large square scales, which is secured with an 18K white gold buckle.

Following in the footsteps of its predecessor, the Ref. 5320G features the same face that has been Patek Philippe’s paragon for perpetual calendars since 1941, as well as draws its inspiration for its three-tier lugs from the legendary Ref. 2405 that dates back to the 1950s. Combining such tradition with innovation, the cadrature is a new facet to the self-winding calibre 324 S Q movement, housing four apertures for the day, month, day/night cycle, and leap-year. In addition to the chronograph’s ability to indicate months with 28, 30 and 31 days, and recognise the 29th of February as a leap day every 4 years, the model’s moon phases is displayed with such precision that a correction by one day is required every 122 years.
