The short answer
A Breguet 7787BR copy is a replica of the Classique 7787 in rose gold: a 39mm dress watch with a moon-phase aperture and a power-reserve display on a guilloché dial. The better copies get the silhouette, the dial pattern and the Breguet hand shape right. They fall short on movement architecture, on whether the complications actually work, and on case thickness. Go in expecting a convincing look rather than a convincing watch, and you will be happy with a good one and disappointed by a cheap one.
Breguet 7787BR Clone Watch Guide: Tiers, Criteria, and What to Check
What the original reference is
“BR” in the reference number is Breguet's code for 18k rose gold, so 7787BR means the Classique 7787 in rose gold rather than yellow or white gold. The genuine watch measures 39mm across, runs the self-winding calibre 591 DRL with a 38-hour power reserve, and carries a moon-phase display plus a power-reserve sector on the dial. Around the case you get the fluted caseband, soldered lugs, a sapphire back and a hand-turned guilloché dial with blued steel hands. That same list doubles as the checklist for judging a copy.
Where copies usually give themselves away
- Moon phase. On the genuine, the disc is driven by a geared wheel and creeps through the month. On many copies the aperture is slaved to a 24-hour disc, so the moon jumps a step every day, or the disc is fixed and never moves at all.
- Power reserve. Wind the watch and watch the needle. On a real one it climbs as the mainspring fills. On copies it often sits at full, or sweeps only part of the arc and then stalls.
- Movement. Most copies stack a moon-phase and power-reserve module on a Miyota 9015 or an ETA 2824 pattern base. The module adds height, and the rotor engraving never matches Breguet's finishing.
- Thickness. The genuine sits a touch over 10mm. Copies with a module often run 11.5mm to 12.5mm, which shows in profile and fights a shirt cuff.
- Dial depth. Real guilloché is cut on a rose engine, so the lines have depth and shift under raking light. Stamped or printed copies look flat, and the pattern breaks where it meets the chapter ring.
Checks you can run before paying
- Ask for a time-lapse of the watch running over 24 hours. The moon should barely move. If it advances a full day, you know what you are buying.
- Ask for photos on a scale. Gold is dense. A plated steel case feels light for its size, and weight is one of the few things you can verify from a picture.
- Ask for a raking-light video of the dial, shot from the side, to see whether the guilloché has relief.
- Ask for movement photos with the caseback removed.
- Ask about the strap and buckle. Grained calf and alligator are not the same thing, and buckle engraving is usually cleaner on the better builds.
What a copy cannot give you
A 7787BR copy is not a Breguet. It has no collector value, no service relationship with the brand, and no resale market the way a genuine reference does. Copies and counterfeits fall under trademark law and customs seizure in Switzerland and in most import markets, which is why honest sellers describe them as copies and price them as copies. Buy one because you like the design and the price, not because you expect it to behave like an 18k gold watch. Servicing is the other reality: any watchmaker can handle a base movement, but the module that drives the moon phase is a different story, and parts for it can be hard to source years later.
Does it suit your wrist
At 39mm with a slim bezel, it wears larger than the number suggests, and it is a formal watch. It works with a suit, a dress shirt and a tuxedo, and it looks out of place with a t-shirt and shorts. If you want this reference for daily wear, a thinner copy without the module sits better under a cuff, though you lose the moon phase. If you want the complication, accept the extra millimeter or two and study the profile photos closely before you buy.
