Patek Philippe Perpetual Calendar Reference 5320G-001

Partially verified

Housed in a 40mm 18-karat white gold case with a stepped bezel, it displays a cream opaline dial with luminescent Arabic numeral indices. The time and calendar functions are driven by the automatic Patek Philippe Calibre 324SQ movement, which contains 29 jewels and provides a 45-hour power reserve. The movement is visible through a sapphire crystal case back. The watch is fitted with a signed brown alligator leather strap secured by an 18-karat white gold folding clasp. Documentation accompanying the timepiece includes the factory certificate of origin dated 2018. The watch exhibits syringe-style hands and incorporates peripheral displays for the perpetual calendar indications, including a sub-dial at the 6 o'clock position for the date and moon phase.
