Patek Philippe Nautilus 5711/1A-010
Known as The Blue Nautilus, the steel 5711 that ended a 40-year run
The 5711/1A-010 is the last steel time-and-date Nautilus Patek Philippe built before Thierry Stern pulled the plug in January 2021. It is a 40mm stainless steel three-hander with the blue sunburst dial and the horizontal embossed lines that Gerald Genta drew for the original 3700 back in 1976. This is the reference that turned into the most talked-about steel sports watch of the modern era. When Patek confirmed it was discontinued, the market did something we had never seen on a steel watch: it tripled a $35,000 list price inside a year. We have bought and sold plenty of them over the counter here on 47th Street, and the 5711/1A-010 is still the piece most collectors mean when they say the word Nautilus. If you own one, or want one, know what you are holding: a discontinued steel Patek that trades at Grand Complication money.
Produced: The 5711/1A-010 blue-dial reference ran from 2012 to January 2021. Patek updated the movement inside it in 2019, swapping the older caliber 324 S C for the caliber 26-330 S C, so late examples from 2019 to 2021 carry the newer movement with the improved seconds-reset and better winding efficiency. Production of the whole steel 5711 line ended when Thierry Stern discontinued it in writing in early 2021.

Market & Value
Here is the honest pricing picture from the buy side. Patek's last US retail on the 5711/1A-010 was $34,893. Even before discontinuation it traded at a premium on the gray market, roughly $50,000 to $60,000. When Stern confirmed in January 2021 that the steel 5711 was done, the reference set off the sharpest steel-watch spike modern collecting has seen: examples cleared $130,000 within twelve months, and unworn pieces touched north of $200,000 at the early-2022 peak. The market has come off that top. As of 2026, WatchCharts has the steel 5711/1A model trading around $112,500, up nearly 30 percent year over year, with individual 5711/1A-010 listings spread from the low $60,000s to $170,000 depending on year, set completeness, and condition. Two things move the number more than anything else: full set with box, certificate of origin, and hang tags versus a watch-only, and whether it is a 2019-to-2021 example with the caliber 26-330 movement. We watch this reference closely because we write checks on it, not because we quote a chart. When we make an offer, we are pricing the exact watch in front of us against what we can actually sell it for that week.
What to Know Before You Buy
A few things a serious buyer or seller should have straight. First, the movement split: 5711/1A-010 examples made through roughly 2019 use the caliber 324 S C, and examples from 2019 onward use the newer caliber 26-330 S C with the redesigned seconds-reset. Both are legitimate 5711/1A-010 watches, but collectors pay attention to which one they are getting, so the production year matters. Second, completeness is not optional at this price level. A 5711 without its certificate of origin and box takes a real haircut against a full set, and forged papers do circulate, so provenance has to check out. Third, be careful with the later special dials sometimes confused with this piece: the green-dial 5711/1A-014 and the Tiffany-signed 5711/1A-018 are separate references with their own market, not this watch. Fourth, condition on the bracelet and case edges matters more on a polished steel sports Patek than most people expect; over-polished lugs and stretched bracelets both cost money. If you are unsure what you have, the reference and movement caliber are the first two things to confirm.
