Patek Philippe Off-Catalogue Emerald Set Perpetual Calendar

The 5271/13P-001 is among the rarest expressions of Patek Philippe's Grand
  Complications collection, an off-catalogue perpetual calendar chronograph in
  platinum, set with 58 baguette-cut emeralds on the bezel and a single emerald
  at twelve o'clock. The hand-wound Calibre CH 29-535 PS Q delivers perpetual
  calendar, chronograph, and moon phase through one of the most technically
  accomplished movements in current production, with a 65-hour power reserve. At
   41mm and 12.7mm thick, it wears with the authority its complications demand.
  Introduced at Baselworld 2017, this is a piece produced in extremely limited
  numbers and seldom seen on the open market.
