The 5711/1A-010 is the modern steel Nautilus, the reference that picked up the 3700's silhouette in 2006 and ran for fifteen years until Patek discontinued it in 2021. 40mm, 8.3mm thick, the embossed-horizontal-line dial, and the H-link integrated bracelet. It is also the watch that more than any other defined the 2017-2022 sport-watch bubble; the steel-blue dial trading at multiples of retail is the canonical example of the market that the period produced.
The 5711 replaced the 3710 in 2006, dropping the power-reserve sub-dial and returning to the original 3700 layout, a single, uninterrupted laydown of the embossed dial pattern. The first-generation 5711 (2006-2019) used the caliber 324 S C, with a screwed case-back. The second-generation (2019-2021) introduced the caliber 26-330 S C, a re-engineered automatic with an improved escapement, a stop-seconds function, and a re-designed case-back.
Steel-blue was the canonical dial; the 5711/1R-001 (rose gold, brown dial) and 5711/1A-014 (slate-grey) trade as their own variants. The 5711/1A-018 'Tiffany & Co' co-signed dial (2021, 170 examples) and the 5711/1A-014 50th-anniversary green dial (2021) are limited references that command substantial premiums.
Common things to check: dial originality (Patek dials are heavily service-replaced, verify the 'Patek Philippe Genève' wordmark printing and the indices for crisp applied work); bracelet end-link generation (the H-link bracelet evolved subtly across the production run, verify the end-link and clasp match the case era); case finishing (the alternating polish/brush on the Nautilus case is hand-applied, over-restored examples lose the definition that makes the watch); first-gen caliber 324 vs second-gen 26-330 (the 2019 movement upgrade matters for service planning); papers and Patek extract (a 5711 without papers in this price bracket is a hard pass for most buyers); the Tiffany-signed and 50th-anniversary variants are the most-counterfeited 5711 references, provenance from Patek's extract service is the standard verification.
