An iconic and rare cushion-shaped steel diving watch, featuring a black "sigma" patterned dial with stunning blue reflections, applied white gold hands and hour markers with patinated tritium, and a date window at 3 o'clock. Mechanical self-winding movement, Caliber 28-255 C., with an original steel bracelet featuring a folding clasp. Comes with its archive certificate. The watch is in excellent condition, both mechanically and aesthetically; the dial is virtually flawless, and the patina of the luminous material is uniform. Only the Calatrava cross on the folding clasp, which is still visible, shows signs of wear. The result of a timeless collaboration between Patek Philippe and Gerald Genta, a designer highly regarded in the watchmaking world, the Nautilus’s unique design draws inspiration from the massive proportions of ship portholes and is named after Captain Nemo’s submarine in Jules Verne’s *Twenty Thousand Leagues Under the Sea*.
