Patek Philippe has launched the latest self-winding perpetual calendar with a contemporary "vintage" style in a case with three-tier lugs as well as a lacquered cream dial graced with luminous numerals and hands. The timepiece was inspired by exhibits in the Patek Philippe Museum from the 1940s and 1950s. Its heart is a newly developed caliber 324 with a double apertures for the day/month and an analog date.
Patek Philippe’s Ref. 5320G is a perpetual calendar that deserves to be called a creation for eternity. The watch not only displays the correct date for months with 28, 30, and 31 days but also indicates the 29th of February, the leap day, every four years. Its design is timelessly sleek, at once reflecting the past, the present, and the future. The dial shows the same configuration that Patek Philippe chose in 1941 to define the classic face of the perpetual calendar: a double aperture for the day and month at 12 o'clock as well as a subsidiary
dial at 6 o'clock for the analog date and the moon phases. These displays are complemented with two small round apertures for the day/night indication and the leap year cycle. The self-winding caliber 324 S Q with a Spiromax
balance spring made of Silinvar
combines superb watchmaking traditions with latest-generation technology. It is protected by a retro-modern white-gold case with three-tier lugs and is reminiscent of the legendary 1950s Ref. 2405. This subtle vintage aspect is underscored by the box-style sapphire-crystal glass that perceptibly overlaps the bezel. The sapphire-crystal case back exposes the architecture of the movement and its refined finissage, including the bridges with chamfered and polished edges, the Geneva striping, and the Calatrava cross engraving on the 21K gold rotor.
