Patek Philippe 5327G-001 is rare for a heavy-hitting perpetual calendar to be this adaptable. This Grand Complications Perpetual Calendar ref. 5327G-001 features classic 39mm dimensions and scalloped lugs that give the case a trim profile on the wrist. The sunburst blue dial hosts applied white gold Breguet numerals and a balanced layout tracking the day, month, date, leap year, 24-hour indication, and lunar cycle. Operating underneath is the ultra-thin automatic Caliber 240 Q, featuring an off-center 22K gold mini-rotor visible through the sapphire caseback.

This is a pre-owned Patek Philippe Grand Complications Perpetual Calendar 18K White Gold Watch 5327G-001. It comes with the manufacturer’s box and its official papers.
