Overview
A perpetual calendar in the vintage manner
The Patek Philippe Grand Complications Perpetual Calendar, reference 5320G-011, in white gold with a rose-gilt opaline dial, charcoal grey applied numerals and syringe-shaped hands, on a shiny chocolate brown alligator strap. Self-winding calibre 26-330 S Q with the day and month in a double aperture and the date by hand; 40 mm, 11.13 mm high.
The reference 5320G-011 is Patek Philippe's perpetual calendar on the self-winding calibre 26-330 S Q, in the Grand Complications collection, which the brand presents as a vintage-style classic. The case is white gold, 40 mm across and 11.13 mm high, made in a single piece with three-tier lugs and sharp angles, and hand-polished throughout. The dial is rose-gilt opaline with applied numerals and syringe-shaped hands in charcoal grey white gold, both with white luminescent coating, on a shiny chocolate brown alligator strap with a white gold fold-over clasp.
The calendar layout is one Patek Philippe describes as a signature of the brand: the day and month sit side by side in an in-line double aperture at 12 o'clock, the date is read by a hand around the moon-phase aperture at 6 o'clock, and the leap year and day/night indications sit in apertures as well, with sweep seconds from the centre. The calibre 26-330 S Q winds through a 21K gold central rotor and measures 32 mm across and 4.97 mm high, with 368 parts and 29 jewels; it runs at 28,800 semi-oscillations an hour on a Gyromax® balance with a Spiromax® balance spring, for a power reserve of 35 to 45 hours, and carries the Patek Philippe Seal. The crystal is a sapphire 'box' glass with a convex profile, which Patek Philippe credits with keeping the case height down.
For collectors
Patek Philippe presents the 5320 as the vintage-style reading of its perpetual calendar: the three-tier lugs, the box-shaped crystal and the rose-gilt opaline dial are this reference's own points, while the calendar layout — the double aperture at 12 o'clock, the date by hand at 6 o'clock — is one the brand describes as a signature layout the brand uses across its perpetual calendars.
