Short answer
7787BR is a Breguet reference, not a Rolex reference. Written in full it is 7787BR/12/9V6. The number 7787 is the model: a Classique with a moon phase and a power reserve indicator. BR is Breguet's code for 18k rose gold. The same brand uses BB for white gold and BA for yellow gold. A replica 7787BR is a counterfeit of that watch. It is not a Breguet product, not a factory variant, and not legal to import into the United States.

What counterfeit 7787BR watches get wrong
- Movement. Copies use a Chinese or Japanese automatic movement with added modules. There is no silicon escapement and no 591 DRL architecture. Repair shops can spot the difference in minutes.
- Moon phase. A real moon phase disc turns once in about 29.5 days. Many counterfeit moon phase watches use a 24-hour disc, so the moon crosses the aperture once per day. Some copies have a printed disc with no moving part.
- Guilloche. Genuine dials are cut by hand on a rose engine. Copies are stamped or molded. The pattern is shallow and repeats with machine regularity.
- Gold. Rose gold color on copies comes from plating. Plating wears at the lugs, bezel edge, and caseback lip. Genuine rose gold is alloyed through the metal and carries 750 stamps and maker marks.
- Weight. A solid gold case weighs more than a plated brass or steel case of the same size.
- Finish. Caseback engraving, rotor decoration, and screw heads show tool marks on copies.
Legal status in the United States
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. For an individual, penalties run to 10 years in prison and a $2,000,000 fine. Importing counterfeit items is barred under 19 U.S.C. 1526, and Customs and Border Protection seizes shipments at the border. A buyer who orders from an overseas seller can lose the money and the item at the same time.
Service and resale
Breguet will not service a counterfeit. Many independent watchmakers decline the work because no parts exist. A counterfeit has no resale market beyond buyers of counterfeits, and no auction house will take one. A genuine 7787BR holds value and can be authenticated by a watchmaker or by the brand.
Checks before buying a 7787BR
- Confirm the reference. 7787BR is rose gold. A steel or two-tone case under that reference is wrong.
- Compare caseback engraving with brand photos. Font, spacing, and depth all matter.
- Ask for a photo of the movement through the sapphire back.
- Ask for the serial number and the original paperwork, then have a watchmaker open the case.
- Watch the moon phase over several days. A full turn in one day means the disc is not a moon phase.
