Patek Philippe Grand Complications 5320G-001 -A Masterpiece of Horological Excellence

Indulge in the pinnacle of Swiss watchmaking with the Patek Philippe Perpetual Calendar, introduced at BaselWorld 2017. This extraordinary timepiece represents the perfect marriage of heritage-inspired design and contemporary mechanical sophistication.

Exquisite Design & Craftsmanship
Housed in an elegant 40mm 18K white gold case, the 5320G captivates with its warm ivory cream dial adorned with applied black gold Arabic numerals and syringe-style hands, both filled with Super-LumiNova. The plexi-evoking glassbox sapphire crystal adds a vintage touch that perfectly complements the mid-century aesthetic.

The case features triple-stepped and gently curving lugs in a Deco design, showcasing Patek Philippe's mastery of refined details. Remarkably, the case is actually a single piece of gold, demonstrating exceptional manufacturing prowess.

Mechanical Excellence
At the heart of this grand complication beats the self-winding caliber 324 S Q with perpetual calendar and central seconds. Equipped with 29 jewels and offering a power reserve of up to 45 hours, this movement represents the first time the base 324 has had a perpetual module, with finishing, as with all things Patek, superb.

Sophisticated Complications
The dial layout is beautifully balanced, with day and month apertures at the top, and a moonphase display and pointer date at the bottom, flanked by relatively discreet portholes displaying day/night and leap year indicators. This perpetual calendar will accurately track the date through centuries without manual adjustment for leap years.
