The Patek Philippe Nautilus reference 5712/1A-001 is an iconic luxury sports watch that evolved from the original 1976 Gerald Genta design. This model features a 40mm stainless steel case with the collection’s signature rounded octagonal bezel and a remarkably slim profile of approximately 8.52mm. The dial is characterized by its horizontally embossed pattern in a gradient blue-black finish, protected by a sapphire crystal. It is powered by the ultra-thin self-winding caliber 240 PS IRM C LU, which utilizes a 22k gold micro-rotor to maintain its slender dimensions while providing a power reserve of up to 48 hours.
The timepiece is noted for its asymmetrical but balanced dial layout that incorporates several complications. These include a power reserve indicator between 10 and 11 o’clock, a pointer date and moon phase display at 6 o’clock, and a small seconds sub-dial between 4 and 5 o’clock. The watch is integrated with a stainless steel bracelet featuring a fold-over clasp and is water-resistant to 60 meters. Its construction emphasizes a mix of polished and satin-brushed finishes, maintaining the nautical-inspired aesthetic of the Nautilus line.
General reviews of the 5712/1A-001 frequently praise its exceptional wearability and elegant proportions, often noting that it sits comfortably low on the wrist compared to thicker complications. Collectors highly value the poetic arrangement of the dial and the technical sophistication of its ultra-thin movement. While it was a staple of the catalog since its release in 2006, its reported discontinuation in early 2025 has significantly increased its desirability and status on the secondary market. Some minor criticisms have historically focused on the relatively low water resistance for a sports watch and the specific bead-blasted or mirror finishes on the moon phase wheel depending on the production year.
