Encased in 18K white gold, its unmatched flyback chronograph shines through an opaline blue dial with horizontal embossing. Collectors seeking singular Nautilus prestige add this reference to anchor their complication collection with irreplaceable versatility.

Presents itself in mint condition with little to no signs of wear. Sunburst blue dial radiates with horizontal embossing and luminous white-gold indices, drawing the eye to its gradient depth. Highly polished and satin-finished octagonal bezel gleams on the 40.5mm 18K white gold case, capturing the signature porthole aesthetic. Sapphire exhibition caseback reveals refined movement finishing, offering an intimate view of the craftsmanship. Blue denim-textured calfskin strap adds contemporary edge to precious-metal refinement.

Functions include hours, minutes, small seconds, date, and flyback chronograph. The screw-down octagonal crown at 3 o’clock quick-sets the date disc and minute hand. Pusher at 2 o’clock starts and stops the chronograph, while pusher at 4 o’clock enables flyback resets to zero. Automatic movement delivers 55-hour power reserve for extended reliability.

Comes as a full set, double-boxed with watch pillow, certificate of origin, leather folder, instruction manual, adjustment stylus, hang tag, and additional fabric strap.

Captures Patek’s chronograph artistry in its most distilled elegance. Enriches your legacy with a presence that commands quiet admiration across generations.
