A replica Patek Philippe Nautilus 6790 is a counterfeit watch that copies the look of the genuine Nautilus, assembled in Chinese workshops and sold online for a small share of the real price. Build quality runs from cheap quartz copies to high-tier "super clone" automatics, and the reference number on the caseback often means little. In the United States, importing, selling, or trafficking a counterfeit watch is illegal, so the risk sits with the buyer and the reseller.

What Is the Patek Philippe Nautilus 6790?

The Nautilus arrived in 1976 as Patek Philippe's steel sports watch, drawn by Gerald Genta. Its shape borrows from a ship's porthole: a rounded octagonal bezel, a slim case with side ears, and an integrated bracelet that flows into the case. Known Nautilus references include the 5711, 5712, 5726, 5980, 5990, and 5740.

Shoppers see the 6790 number in replica listings far more than in Patek's own catalog. Some listings copy a real reference and mislabel it; others invent a number to dodge brand takedowns. Check the brand's official site for the reference you think you are buying before you trust any listing.

Design cues a replica tries to copy

  • Rounded octagonal bezel with a satin top and polished bevel.
  • Integrated bracelet with tapered H-shaped links and a folding clasp.
  • Horizontally embossed dial with a date window at 3 o'clock.
  • Caseback with an engraved reference, serial, and movement number.

Why the reference number is a weak signal

Factories rename batches when a popular number gets flagged. A "6790" from one seller can ship with a different dial, case size, or movement than a "6790" from another. Ask for photos of the actual watch you will receive, not stock renders.

How Does a Replica Nautilus Compare to the Genuine Watch?

The gap shows up in three places: the movement, the finishing, and the materials. A real Nautilus runs a Patek in-house caliber with hand-finished bridges. A replica runs a mass-produced Asian movement with stamped parts.

  • Movement: genuine uses an in-house automatic; replicas use copied ETA or Miyota designs.
  • Gold content: solid rose or white gold models carry real precious metal; replicas use plated steel that wears through.
  • Dial texture: genuine dials have a soft vertical gradient and crisp embossing; replicas show flat color and shallow lines.
  • Case finishing: genuine bevels are sharp and even; replica edges look rounded under a loupe.
  • Weight: a gold Nautilus feels heavy; a plated steel replica feels light.
  • Service: Patek services its watches for decades; no one services a counterfeit.

Replica Quality Tiers

Budget tier (under $150)

Quartz or basic automatic movement, mineral glass, printed dial, and a hollow bracelet. These look wrong from a few feet away. Water resistance is a claim, not a fact, so keep them away from pools and showers.

Mid tier ($200 to $500)

Asian automatic movement with a date, sapphire crystal, and a solid link bracelet. The case shape is close, but the dial texture and clasp details give it away. Fine for casual wear, not for close inspection.

High tier ($600 and up)

Cloned movements, closer case dimensions, and better brushing and polishing. Sellers call these "1:1" or "super clone." They still fail next to a real Nautilus, and they carry the same legal exposure as a $40 copy.

What to Check Before You Buy

  1. Movement type and maker, plus whether it hacks and hand-winds.
  2. Case diameter and thickness against the reference you want.
  3. Dial photos in outdoor light, not studio renders.
  4. Bracelet link count, taper, and clasp engraving.
  5. Water resistance claims. Treat any rating as unproven.
  6. Seller return policy and payment method. Chargebacks are hard on wire transfers.
  7. Price sanity. A "gold" Nautilus for $300 is plated steel.

Legal Risk in the United States

Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320, with penalties that reach prison time for repeat offenders. U.S. Customs and Border Protection seizes counterfeit watches at ports and mail centers, and the shipment is destroyed. Patek Philippe holds trademarks on the Nautilus name, the dial layout, and the logo, so reselling a replica invites a civil suit from the brand.

Owning a counterfeit watch for personal use seldom leads to charges. Selling, importing, and shipping them is a different story. Keep that line in mind if you plan to flip anything you buy.

FAQ

How much does a replica Nautilus 6790 cost?

Budget copies sell for under $150, mid-range automatics land between $200 and $500, and high-tier clones start around $600. Any price far below those bands means quartz, plated metal, or a scam.

Will a jeweler or watchmaker spot a replica?

Yes. Trained eyes check movement finishing, case bevels, dial texture, and weight at a glance. A watchmaker who opens the caseback will know at once.

Does a replica Nautilus hold value?

No. Replica watches lose most of their value the moment they ship, and no auction house or dealer will take one. The genuine 5711 and 5990 hold value because supply is limited and Patek controls it.

Is buying a replica watch legal?

Buying for personal use seldom leads to charges in the US. Importing it through customs, selling it, or shipping it to a buyer does carry real legal risk.

The Short Version

A replica Patek Philippe Nautilus 6790 is a counterfeit, not a budget alternative. The reference number tells you little, quality depends on the tier you pay for, and the legal exposure lands on anyone who imports or resells one. If you want the Nautilus look without the risk, buy a legal steel sports watch from a brand that sells one.
