A genuine Breguet 7787BR uses a solid gold case with Swiss hallmarks, a hand-engraved guilloché dial, and a signed Calibre 591 DR movement. Replicas fail on hallmark crispness, dial engraving depth, and movement finishing. Use the checks below to tell them apart.
Before you start
- Ask for high-resolution photos of the caseback, dial, and movement.
- Request the original certificate and service records.
- Have a watchmaker inspect the movement if possible.
How to authenticate a Breguet 7787BR
- Check the case hallmarks for the Swiss assay mark and the Breguet serial number inside the caseback.
- Examine the dial engraving under a loupe for consistent depth and no tool chatter.
- Inspect the hands for blued steel with a polished finish and a hollow moon tip.
- Look at the moonphase aperture for a grained sky and a well-defined moon.
- Inspect the movement through the caseback for Geneva stripes and a signed rotor.
- Verify the serial number on the caseback matches the certificate.
- Test the winding and moonphase pushers for smooth operation.
What replicas get wrong
Most replica Breguet 7787 BR watches copy the outside shape but miss the finishing. Common tells include a thick caseback, a flat dial, a noisy rotor, and a moonphase that does not track correctly. If the price is far below market and the seller avoids serial checks, walk away.
Buying safely
Buy from an authorized Breguet dealer or a reputable auction house. Avoid sellers who push replica or mirror quality. Counterfeit watches are illegal to sell in the US and many other countries, and they carry no warranty or service support.
