Quick answer
A replica Breguet 7787 is an unauthorized copy of a watch from Breguet's Classique line. No factory outside Breguet holds the drawings, the rose engine, or the movement. A replica is a different object with a Breguet name on the dial. Selling one is a federal crime in the United States. Importing one is a customs violation. A replica has no Breguet service, no Breguet parts, and no resale value.
Replica pricing moves with movement grade and seller. Public price data is thin because the trade is illegal. A genuine reference 7787 in a gold case trades in the five figures on the secondary market.
What the reference number marks
Breguet uses four digit references to mark one case, dial, and movement combination. The 7787 sits in the Classique family. Classique watches share a set of traits: a silvered dial with hand engine turned guilloche, blued steel Breguet hands, a fluted caseband, welded lugs, a sapphire caseback, and a signed crown. Dial layout, case size, and caliber for 7787 change with production updates. Check Breguet's own catalog for the current sheet.
What separates a replica from the genuine watch
- Movement: Breguet builds its own calibers in Switzerland. Replicas use mass produced movements, often with a decorated rotor and a copied bridge shape.
- Dial: Breguet cuts the pattern by hand on a rose engine. Replicas stamp or print the pattern.
- Case: Breguet welds the lugs to the caseband. Replicas machine the case as one piece or braze the lugs.
- Numbering: genuine watches carry a serial number and a case number, both recorded. Replica numbers are lifted from photos of real watches.
- Materials: gold cases carry hallmarks and a maker's mark. Replicas use gold plating over brass or steel.
- Hands: genuine hands are blued steel. Replicas use painted or plated metal.
Legal status in the United States
18 U.S.C. Section 2320 makes trafficking in counterfeit goods a federal crime. Penalties reach 10 years for a first offense and 20 years for a repeat offense. Statutory damages under the Lanham Act reach $2,000,000 per counterfeit mark per type of goods when the use is willful. U.S. Customs and Border Protection can seize counterfeit watches at a port of entry. Import for personal use is not an exemption. This paragraph describes the law in general terms and is not legal advice.
Service, parts, and resale
Breguet service centers do not accept replicas. An independent watchmaker can swap a movement but cannot source Breguet parts for a copy. Resale value on a replica sits near zero. Marketplaces pull listings when the trademark owner files a complaint. A buyer who pays for a replica holds an item that cannot be repaired to original condition and cannot be sold on.
How to check a watch sold as a 7787
- Ask for the serial number and the case number. Confirm both with Breguet.
- Look at the dial pattern under a loupe. Hand cut guilloche shows crisp, continuous ridges. Stamped patterns show rounded edges.
- Check the hallmarks inside the caseback. Gold cases carry a purity mark and a maker's mark.
- Compare bridge finish, screw heads, and engraving against Breguet's published images.
- Ask for the warranty card, the original invoice, and the service history.
Bottom line
A replica Breguet 7787 copies a dial and a name. It does not copy the movement, the dial work, or the case construction. It carries legal risk in the US, no service path, and no resale value. A buyer who wants the look without the price has legal options: makers such as Longines, Raymond Weil, and Orient sell guilloche dials and Breguet style hands under their own names.
