A fake Patek Philippe 7118 with a blue dial is a copy of the Nautilus 7118/1A, a 35.2 mm steel watch. Replica sellers price these copies from about $300 to $700. The copy matches case shape, bracelet style, and dial layout. It does not match the movement, the dial finishing, or the bracelet polish. The genuine watch retails in the tens of thousands of dollars and comes with a Patek Philippe seal and a service record.

What replica makers copy
Good replicas get the outline right. That is the easy part, because the Nautilus case is a known shape with published dimensions.
- Case profile and the two-ear bezel shape.
- 35.2 mm diameter, which suits a 6.0 to 7.0 inch wrist.
- Bracelet link count and taper.
- Blue dial color and the horizontal embossed band.
- Date position at 6 o'clock.
Where replicas fall short
- Dial finish. The genuine embossed pattern has sharp edges and a satin sheen. Copies show soft edges and a flatter color under low light.
- Date wheel. Font weight and alignment differ. The numeral sits off center on most copies.
- Bracelet. Link bevels are rounded on copies. The clasp engraving is shallow.
- Movement. Copies use a Miyota, a Seiko NH series, or a Chinese clone. None has a 21K gold rotor or a Gyromax balance.
- Caseback. The sapphire is flat on copies, and the movement visible through it is not a Patek caliber.
- Weight. Steel copies run light by a few grams against the genuine bracelet.
Price bands
- $250 to $400: entry tier. Mineral glass, basic automatic or quartz, weak dial printing.
- $400 to $550: mid tier. Sapphire glass, better bracelet finishing, Seiko or Miyota movement.
- $550 to $800: upper tier. Closer dial color and case bevels, clone automatic movement.
No price band delivers a movement that matches the 324 S C. Plan on a service interval of two to three years for any automatic copy, and expect parts to be scarce.
Legal and shipping risk
Counterfeit watches carry a registered trademark. U.S. Customs and Border Protection can seize and destroy them at import. A seizure notice goes to the buyer, and the money is gone. Sellers ship from overseas and rarely refund a seized parcel. There is no manufacturer warranty, no authorized service, and no resale value. Repair shops that will touch a counterfeit are few.
Checklist before paying
- Ask for photos of the date window at 6 o'clock under daylight.
- Ask for a close photo of the clasp engraving.
- Ask which movement the seller installs and the beat rate.
- Confirm the return policy in writing, including seizure terms.
- Check the seller's track record on orders shipped to your country.
Unknown: the exact factory behind most 7118 blue dial copies. Sellers use trade names, and the names change. Treat any claimed factory name as marketing until you see the actual watch.
