A fake Breguet 7787 BR is a replica of the Breguet Classique 7787 in 18k rose gold, where the "BR" suffix marks the rose gold case code. The genuine reference pairs a guilloché dial, a working moon phase and a power reserve sector with an in-house self-winding calibre, so on a copy the differences surface first in the dial engraving, the case thickness and the view through the sapphire back.

What the genuine 7787BR is

The Classique 7787 sits in Breguet's classic dress line. It uses a round gold case of about 39 mm, a silvered engine-turned dial, blued steel Breguet hands, and an exposed caseback that shows the decorated movement and engraved rotor. Two complications define the model: a moon phase display and a power reserve sector that tracks how much energy is left in the mainspring. Breguet also hides a faint secret signature in the dial, a detail that matters when you compare a replica against photos of the real piece.

How replica tiers differ

Not every fake is built the same way, and price tends to follow one of three levels.

  • Entry tier: quartz movement, printed dial pattern, moon disc that is a flat decal, plated case that feels light on the wrist.
  • Mid tier: automatic movement from a third-party supplier, stamped guilloché pattern, moon phase that may run but tracks poorly, power reserve sector that never moves.
  • Top tier: proper plating or a gold-capped case, deeper engine turning, a working moon phase module, decorated rotor, better anti-reflective crystal.

Even the best replica remains a replica. The point of the tiers is to understand what you are looking at if one crosses your bench or your watch roll.

Tells on the dial and hands

  • Guilloché depth: real engine turning catches light in crisp concentric waves. Stamped copies look shallow and uniform, with soft edges where the lines meet the chapter ring.
  • Moon phase: the original shows a smooth moon and stars over a graduated aperture. Fakes often use a printed disc, or one that jumps instead of advancing through the lunar cycle.
  • Power reserve sector: wind the watch and watch the needle. If nothing moves, the sector is painted on.
  • Hands: Breguet hands are hollowed with eccentric moon tips. Copies are often solid with plain round ends and heavier polishing marks.
  • Printing: look at the numerals, the brand text and the secret signature under magnification. Fuzzy edges and uneven spacing are common on fakes.

Case, weight and caseback

Rose gold has a warm tone that holds up in daylight. Plating on a replica can drift toward copper or look flat grey indoors, and it wears thin at the lugs, crown and caseback edge. Gold also has density, so a plated steel case with the same dimensions sits lighter than the genuine article.

Flip the watch over. A genuine Classique shows a finished movement with polished bevelled bridges, blued screws and a rotor engraved with the brand and calibre. Replicas reveal generic finishing, mismatched engraving fonts, or a rotor decorated to imitate a calibre that is not inside. Reference numbers, serials and gold hallmarks are stamped shallow or misplaced.

Movement checks you can do in a minute

  1. Let the seconds hand run. A smooth sweep points to mechanical, a one-tick-per-second jump points to quartz.
  2. Pull the crown and check whether the seconds hand hacks.
  3. Wind the watch and confirm the power reserve sector responds.
  4. Use the corrector to advance the moon phase and see whether the disc moves in small steps.
  5. Measure the case thickness. Added modules for the complications tend to make fakes sit taller than the real profile.

Buying and legal notes

"Fake" and "replica" are used interchangeably in search, but the product is the same: a watch made without authorization from Montres Breguet SA. It carries no brand warranty or service support, holds almost no resale value, and can be seized by customs in many countries. If you want the real complications and the real dial finishing, only the genuine reference delivers them.

Is a fake Breguet 7787 BR identical to the original?

No. Shared dimensions can look close in photos, but the movement, dial engraving, moon phase accuracy and case material are different, and those differences are visible in hand.

Why do fakes of this model vary so much?

The 7787 has two complications, a moon phase and a power reserve, and copying them well costs money. Builders cut costs on whichever one buyers check least.
