Short answer
A fake Breguet Classique 7787BR fails in four places: caseback engraving, dial finish, movement decoration and paperwork. A genuine example carries crisp hand-engraved markings, a hand-finished hand-wound calibre visible through the sapphire back, and matching serial numbers on the case, the movement and the certificate. Copies match the silhouette and miss the details.
Breguet 7787BR Clone Watch Guide: Tiers, Criteria, and What to Check
Before you start
- A 10x loupe or a macro lens.
- Digital calipers and a small jeweller's scale.
- The official spec sheet for the exact reference you are checking, for example 7787BR/12/9V6.
- Clear reference photos of a genuine watch from a dealer or auction archive.
- Access to a watchmaker who services high-end Swiss calibres.
Steps
- Read the caseback and write down every line of text: reference number, case number, the Breguet name, Swiss Made, the gold purity stamp and the maker's mark.
- Check the reference format. Genuine Breguet references follow a fixed pattern where the letters after the model number indicate the case metal, so a rose gold 7787 should show the correct two-letter code for that metal.
- Measure the case with calipers and compare the result against the official diameter and thickness for the 7787, not against a rounded figure you found in a forum post.
- Weigh the watch. Rose gold is dense. A gold-plated case with the same dimensions will come in noticeably lighter on the scale.
- Examine the dial surface under the loupe. The finish should be flat and even, with no orange-peel texture, no trapped dust under the surface and no printing that sits on top of the coating.
- Inspect the printed elements. The numerals, the power reserve scale and any guilloché pattern should have sharp edges under magnification. Copies show fuzzy edges, ink bleed or a flat stamped pattern imitating engine turning.
- Study the moonphase aperture. The disc should be cleanly finished with a defined sky, stars and moon, and the aperture edge should be cut square with no rough burr.
- Check the hands. Breguet hands should be blued steel with polished, mirror-bright sides. Painted or chemically darkened hands are a warning sign.
- Look through the sapphire back at the movement. You want Geneva stripes on the bridges, circular graining on the base plate, polished screw heads, blued screws and deep, even engraving.
- Confirm the calibre type. The 7787 is a hand-wound watch. If you can see an oscillating weight through the caseback, the movement does not belong to that reference.
- Work the crown and the functions. Winding should feel smooth with crisp clicks, the power reserve hand should climb as you wind, and the moonphase should advance one step per day.
- Match every number. The case number, the number on the movement and the number on the certificate should agree. A mismatch is decisive.
- Inspect the papers and the box. Genuine Breguet paperwork uses consistent typography, correct reference and case numbers, and a stamped dealer entry. Plain cards with a printed logo are common with copies.
- Ask an independent watchmaker to open the watch and examine the movement directly. This is the only check that settles the question.
Common tells on a copy
- Engraving on the caseback that looks laser-cut with uniform depth rather than hand-cut with varied strokes.
- A caseback font that is slightly too wide, too tall or spaced unevenly.
- Lume or paint on hands that should be plain polished steel.
- A movement with plated brass parts, visible machining marks or decorative stripes that stop short of the edges.
- Serial numbers that are stamped on the case but missing from the movement.
If the watch fails these checks
Stop the transaction. If you have already paid, keep the watch untouched, photograph the caseback, movement and papers, and put the dispute in writing to the seller or your payment provider. Do not have the watch opened by anyone other than a qualified watchmaker, since a scratched caseback weakens your claim.
What raises confidence
A complete set helps, but paperwork alone proves nothing. Look for a service history from an authorised workshop, matching numbers, and a seller who agrees in writing to a return window of at least seven days. Any seller who refuses an inspection by a watchmaker is telling you something.
