Patek PhilippeGrand Complications Perpetual Calendar

Patek Philippe clearly found inspiration for its 5320g Perpetual Calendar in its rich history, using what might be one of the most important collections of vintage watches to create a series of retro-inspired pieces. The 5320g Perpetual Calendar is not a re-edition of a single watch but instead, it compiles several strong elements of various watches.

Its elegant case measures 40mm diameter and 11.13mm in height. Produced in white gold, its proportions are refined, showing straight lines and sharp angles, as well as flawless polishing. Three step claw lugs sit in harmony with the case.

The watch sports a cream-coloured, lacquered dial that recalls the patina found on vintage watches and is coupled with a highly domed, box-sapphire crystal. Both features add great warmth to the piece and a period-relevant appeal, again without being overwrought. Applied luminous Arabic numerals in blackened white gold with a military style and syringe hands, recall the reference 1591.

For the 5320g, Patek created a new display and we have a combination of windows for the day and month, as well as sub-dial for the date and moon, and finally small circular windows for the leap year and the day-and-night indicator, on each side of the moon. The 5320g is based on a well-known movement of the brand, the automatic with centrally-mounted rotor, Calibre 324 – used in various models. It includes Patek innovations, utilising silicon technology.

Under the large 21k gold rotor are beautifully decorated parts, with round-chamfered and polished edges, Geneva striping and gold-filled engravings, screws with polished, chamfered slots in bores with polished countersinks.

The case, caseback, strap and clasp are in excellent condition with no perceptible marks and the deployment retains a sticker. The box and papers set is immaculate. A refined, original and superbly executed piece.
