Powered by the Caliber 240 Q, an ultra-thin mechanical self-winding movement, this Grand Complications piece displays a full perpetual calendar—day, date, month, leap year cycle, and 24-hour indication—all conveyed through a refined hand-based layout. The 39mm yellow gold case stands 9.71mm tall and is water resistant to 30 metres, with the added versatility of an interchangeable full back alongside a sapphire-crystal case back option.
The ivory lacquered dial is appointed with gold applied Breguet numerals, lending the piece a classical character that complements the warm tone of the yellow gold case. Every detail of the dial composition reflects a restrained elegance suited to the perpetual calendar complication it houses.
The watch is worn on a hand-stitched shiny chocolate brown alligator strap with square scales, secured by a fold-over clasp. Reference 5327J-001 represents a well-proportioned expression of Patek Philippe's Grand Complications lineage.
