Patek Philippe 5204P Grand Complications Platinum Black Opaline Dial SEALED UNWORN

The Patek Philippe 5204P‑011 is a masterful expression of haute horlogerie, combining a split‑seconds chronograph and perpetual calendar in a 950 platinum case. Introduced around 2016, this Grand Complications reference houses the in‑house manual‑wind Caliber CHR 29‑535 PS Q, a movement celebrated for its column‑wheel architecture, horizontal clutch, and seven patented innovations. The ebony‑black opaline dial is rendered on an 18K gold plate and features applied baton markers, luminous dauphine hands, and a sophisticated layout with apertures for day, month, leap year, and day/night, plus a moon‑phase and date subdial. Its 40 mm diameter and 14.3 mm thickness give it a commanding yet elegant wrist presence, while the sapphire display back reveals the finely finished movement. Water‑resistant to 30 meters, the watch is fitted on a hand‑stitched black alligator strap with a platinum fold‑over clasp. A consummate collector’s piece, the 5204P‑011 stands as a technical and aesthetic milestone in Patek Philippe’s chronograph lineage. Unworn and Sealed with Patek Philippe box, additional solid case back, setting pin and papers dated 2016.
