Calatrava Perpetual Calendar Moonphase White Gold Opaline Silver Dial 36mm

The Patek Philippe Grand Complications (ref. 5327R-001) continues the manufacture's perpetual calendar lineage with a refined yet contemporary take on the classic Calatrava silhouette. Introduced in 2016, this rose-gold execution is distinguished by applied Breguet numerals, elegant feuille hands, and a subtle opaline ivory dial that recalls the maison’s vintage perpetual calendars.

Its 39mm case affords a slightly larger presence than earlier models such as the ref. 5140, while remaining faithful to traditional proportions. The perpetual calendar layout includes day, date, month, leap year, and moonphase indicators, all powered by the ultra-thin automatic calibre 240 Q with a discreet micro-rotor and a 48-hour power reserve. Finished to Geneva Seal standards and water-resistant to 30m, the 5327R-001 exemplifies high complications in an effortlessly wearable format.

With its combination of aesthetic warmth and mechanical sophistication, the 5327R-001 reinforces Patek Philippe's leadership in calendar complications—timeless in function, but entirely of its time in form.
