A fake Patek Philippe Nautilus 5711 is a copy of the 40mm steel sports watch that Patek Philippe built from 2006 to 2021. Replica prices run from about $50 for a quartz model to $800 or more for a "super clone" with a decorated automatic movement. The gaps between those tiers show up in case thickness, dial color, date window placement, and bracelet finish.
Patek retired the 5711/1A-010 in 2021 after a run that pushed secondhand prices past $100,000. Replica makers filled the space with dozens of versions, and the quality range is wider than most buyers expect.
Why the Nautilus 5711 Is the Most Copied Patek
The 5711/1A-010 carried a retail price near $35,000 but traded above $100,000 on the secondary market before Patek cut the reference. Copies of a high-demand watch sell better than copies of an obscure one. The plain steel case and three-hand dial also make the design simple to reproduce.
Patek closed the line with the 5711/1A-014 in olive green and a Tiffany Blue edition limited to 170 pieces. Both get copied now.
What Do Fake Nautilus 5711 Watches Cost?
Replica pricing falls into four bands. Each step up buys better materials and a better movement, not authenticity.
- Under $80: quartz movement, printed dial, stamped bracelet, case around 10 to 11 mm thick.
- $100 to $250: automatic movement (often a Miyota or Seagull), better case shape, mineral or low-grade sapphire crystal.
- $300 to $550: mid-tier builds with 316L or 904L steel, sapphire with anti-reflective coating, closer dial color.
- $600 to $900: super clone tier with decorated clone movements, engraved plates, and the closest case profile.
Anything above $1,000 from a non-dealer source is markup, not a better watch.
How to Spot a Fake Patek Philippe Nautilus 5711
Four areas give replicas away: case thickness, dial color, date window, and bracelet.
Case Size and Thickness
A genuine 5711 measures 40 mm across and 8.3 mm thick. Most replicas come in at 9.5 mm or more, and the extra height kills the curve of the bezel. Set the watch on a flat surface and check the gap under the lugs.
Dial Color and Finish
The blue 5711 dial has a soft gradient and reads gray-blue in daylight. Cheap copies show a flat purple or navy tone with no gradient at all. On the olive 5711/1A-014, replicas miss the brushed sunburst and the shade drifts toward brown.
Date Window and Crystal
The date sits at 3 o'clock on a white disc with a font that matches the dial print. Replicas use thicker date fonts, and many set the cyclops magnification at the wrong power. Genuine sapphire shows almost no distortion at the edges.
Bracelet and Clasp
The integrated bracelet tapers from 25 mm at the lugs to 18 mm at the clasp. Replica bracelets run thicker, with sharp inner edges and loose play between links. Clasp engraving on copies is shallow and often misspelled.
Movement and Case Back
Patek fitted the 26-330 S C caliber to later 5711 watches and the 324 S C to earlier ones. Both are visible through a sapphire case back. Replicas hide a Miyota 9015, a Seagull ST, or a decorated clone behind a printed plate, so check jewel count, rotor finish, and engraving depth.
What Even High-End Replicas Still Get Wrong
- Crown height and thread pitch, which sit too high on most copies.
- Weight, since steel replicas feel lighter in the hand than the genuine watch.
- Dial printing, where genuine text uses a finer, tighter font.
- Bezel bevel, which has a sharp mirrored edge on the real watch.
None of these fix a case that is 1.5 mm too thick. That measurement is the single hardest part of the Nautilus to copy.
Quartz, Automatic, or "Swiss Clone"?
A quartz fake ticks once per second and needs a battery. Automatic copies sweep, but many keep worse time than a $100 Seiko. Sellers who advertise a Swiss clone movement mean a Chinese or Japanese movement with Swiss-looking engraving.
Ask for a photo of the movement through the case back. A real decorated rotor and blued screws cost more than the rest of the watch.
Risks of Buying a Fake Nautilus from China
US customs can seize counterfeit watches, and importing them violates trademark law. Buyers also face the wrong tier arriving, dead-on-arrival movements, and no path to a refund. Selling a replica as a genuine Patek is fraud and carries criminal penalties.
Can You Tell a Fake 5711 on the Wrist?
From two feet away in low light, a $600 replica can pass. Up close, the case thickness and the dial gradient expose it to anyone who has handled the real watch. The genuine watch also feels heavier when you pick it up.
Quick Checks Before You Buy
- Ask for caliper photos that show case thickness.
- Request a video of the date change at midnight.
- Compare the dial photo against a reference image shot in daylight.
- Confirm bracelet length and link count.
- Pay with a method that allows a chargeback.
