A fake Breguet 7787 BR is a replica of the Breguet Classique 7787BR/12/9V6, a 39 mm rose gold dress watch with a silvered guilloché dial, a moon phase, and a power reserve indicator. Replica quality comes down to four parts: the dial pattern, the moon phase disc, the movement, and the case and engraving.

What does the genuine Breguet 7787BR look like?

The real 7787BR/12/9V6 uses an 18k rose gold case measuring 39 mm across. Breguet fits it with the self-winding caliber 591 DRL, which carries a 38-hour power reserve and drives a moon phase aperture and a power reserve sector on the dial. The dial itself is silvered gold with hand-turned guilloché, Roman numerals, and blued steel Breguet hands with eccentric moon tips.

Which details decide replica quality?

Dial guilloché

Genuine Breguet dials are cut on a rose engine, so the pattern stays crisp with sharp intersections and no flat patches. Cheap replicas stamp or print the guilloché, which looks shallow under raking light and blurs near the center. High-tier fakes now use CNC-cut or stamped dials that read correctly at arm's length.

Hands and the secret signature

Breguet hands are blued steel, hollow, and finished with a small eccentric ring at the tip. Replicas often use solid hands or simply paint them blue instead of heat-blueing the metal. The secret signature, an etched Breguet mark hidden in the guilloché near 12 o'clock, is either missing or far too bold on lower-grade copies.

Moon phase

A working moon phase is the hardest function to fake at low cost. Entry replicas use a printed disc that turns once every 24 hours, while better copies use a 29.5-day cycle driven by a dedicated gear train. Check that the moon disc advances at the right pace and that the two moons are engraved rather than printed flat.

Movement

Most fake 7787 BR watches run on a modified ETA 2892, a Seagull ST series caliber, or a Chinese clone with a moon phase module bolted on top. The best replicas use a decorated automatic movement with perlage, blued screws, and a rotor engraved to resemble caliber 591 DRL. None of them hold a true 38-hour reserve with total consistency, but a smooth sweep and a quiet rotor are good signs.

Case and caseback

Rose gold plating on a replica wears through at the lugs and crown within months of daily use. Look for thick PVD or, at the top end, solid 18k gold cases from specialist builders. Caseback engraving on a good fake lists the reference, the movement, and the hallmark placement in the same font weight as the original.

How much should a high-end fake Breguet 7787 BR cost?

Low-grade copies sell for under $150 and often drop the moon phase or the power reserve function. Mid-tier replicas with a working moon phase land between $300 and $550, and top-tier builds with a decorated automatic movement and real gold plating run $600 to $900. Anything above that range is seller markup, not better construction.

Frequently asked questions

Does the replica Breguet 7787 BR have a real moon phase?

Only mid-tier and top-tier replicas do. Ask the seller for a video showing the moon disc moving across several days, because a still photo cannot prove a 29.5-day cycle.

Can a jeweler tell a fake Breguet 7787 BR from the real watch?

Yes, and almost always from the movement. A watchmaker who opens the caseback will see the wrong bridge layout, wrong jewel count, and missing Breguet finishing within seconds.

What is the best tell on the wrist?

The guilloché. Genuine hand-turned patterns catch light in continuous lines, while stamped replica dials break into flat patches when you tilt the watch.
