The short answer
A replica Breguet 7787BB is a copy of the Breguet Classique 7787 in white gold. The reference code tells you the metal: Breguet uses BB for white gold, BR for rose gold, BA for yellow gold and PT for platinum. The real watch is a 39mm dress piece from the Classique line with a moon phase and a power reserve reading, and it sells well into five figures. A first-copy version runs a few hundred dollars and contains none of Breguet's parts. Judge one on the case, the dial, the hands and the movement, not on the listing photos.
What you are comparing against
The Classique 7787 is one of the quieter Breguet models. Round case, 39mm across, thin enough to sit under a cuff. The caseband is fluted, a house signature that reaches back to Abraham-Louis Breguet, and the lugs are straight and welded rather than screwed on. Roman numerals, a moon phase, a power reserve reading, and Breguet hands: blued steel with the eccentric tip that finishes in a hollowed circle. The house signature sits on the dial as well, and Breguet has used a partly hidden version of it on some references, a detail counterfeiters tend to skip.
Dial material changes with the variant. Some 7787 pieces use a hand-guilloche surface, others a fired enamel disc. Either way the surface has depth, and you see it catch light when you tilt your wrist. That is the first thing to die in a cheap copy.
What the replica market actually sells
There is no single 7787BB replica. There are tiers.
- Entry tier. Quartz or basic automatic, plated brass or steel case, printed dial texture, mineral glass, generic strap. Roughly $50 to $150.
- Mid tier. Decorated automatic movement, steel or tungsten case, cleaner dial printing, better moon disc, signed crown and caseback. Roughly $200 to $450.
- Top tier. The ones sold with 1:1 and Swiss made language. Better finishing, real sapphire, sometimes a genuine leather or alligator strap, a Miyota or Seagull base under added decorative plates. Roughly $500 and up.
None of them carry a Breguet calibre. A listing that claims otherwise is either lying to you or charging you for a story.
What to inspect before you pay
- Case diameter and thickness. Measure or ask. A 42mm 7787 is not a 7787.
- Flutes on the caseband. They should be fine, even and vertical. Chunky, uneven flutes read as cast, not machined.
- Hands. Blued steel beats painted black. Look for the hollow circle near the tip and a thin, clean profile.
- Moon disc. A flat printed disc with a pasted-on photo looks wrong on the wrist. Better ones have tonal depth.
- Dial texture. Stamped guilloche looks like a waffle iron. Printed texture looks like paper.
- Caseback engraving. Reference and serial numbers should be crisp, not shallow laser burns.
- Weight. Gold is heavy, steel is not. Tungsten copies the heft but is brittle and awkward to service.
- Strap and buckle. Ask for real photos of the unit you will receive, not catalog shots.
Match the complication layout to Breguet's own product photo for that exact reference before you compare anything else. Get the layout wrong in your head and every other judgment follows it.
Ask these questions first
Can you send photos of the actual watch holding today's date? What movement is inside, by name? What is the return policy, in writing? Do you accept a payment method with buyer protection? Sellers who take crypto or bank transfer only, and who dodge requests for fresh photos, are the ones to walk away from.
Price and shipping reality in the US
Counterfeit branded goods are a trademark problem, not a gray hobby. US Customs can seize an inbound parcel of counterfeits, and selling goods with a counterfeit mark carries real criminal exposure. Buying one to wear is a lower risk than reselling, but the package passes through the same screening either way. Budget for the chance that it never arrives, and never treat a replica as an investment.
Bottom line
The 7787BB is a restrained, finely finished dress watch, and restraint is what replicas handle worst. Two complications on one dial, a fluted case and blued hands are hard to fake at a low price. If you want the look, pick the tier you can verify in real photos, accept that the movement will be generic, and go in knowing you are buying a stand-in rather than a Breguet.
