Patek Philippe Perpetual Calendar 5320G, White Gold

The 5320G has a glossy, cream-coloured lacquered dial with two, uniform apertures for the day and month, and a moon-phase display and date array at six o'clock. The dial is classically understated, balancing the outer-minute track perfectly. The watch displays four hands - hours, minutes, and seconds for the time, with the date indicator at six. Overall, the dial layout is cleanly designed, with two discrete windows showing the leap year and day-and-night indicators, respectively, on each side of the moon.

Inside the watch, the 5320G movement is based on the calibre 324, with centrally-mounted, 21-carat solid-gold rotor. The calibre 324 S Q (’S’ for seconds, ‘Q’ for quantième perpétuel) serves as a refined perpetual calendar version of the self-winding 324. The watch features Patek Philippe's Gyromax balance and Spiromax balance spring (in Silinvar), and the case itself is actually a monobloc construction, stamped from a single piece of gold. The case again draws inspiration from Patek Philippe’s extensive archive (much like the dial), with three-tier ‘claw’ lugs (now seen on the 5172G).

As with all contemporary Patek Philippe watches, it has the Patek Philippe seal, guaranteeing its accuracy to -3 and +2 seconds daily, keeping time better than the industry benchmark chronometer grade movements. The movement is beautifully finished, with exquisite chamfering on all angles, polishing and decoration, in the form of Geneva striping.

This example comes as a full-set, currently fitted on our Antwerp grey strap, with an original Patek Philippe, chocolate brown, alligator strap; Patek Philippe white-gold deployant and its accompanying box and original paperwork.

Viewings can be arranged in Central London by appointment.
