Patek Philippe revisits the sporty style of the Aquanaut chronograph in a rose gold version, paired with a sunburst brown dial featuring a black-gradient rim and matching composite strap. The original design of the case (water-resistant to 120 m) and the bezel is highlighted by the alternating polished and satin-brushed finishes. The self-winding flyback chronograph movement combines tradition (column wheel drive) with innovation (vertical disk clutch). Since the clutch causes almost no wear, the central chronograph seconds hand can also be used to display the seconds continuously. WATCH Self-winding mechanical movement. Caliber CH 28‑520 C.
