The version of the fake Breguet Classique 7787 worth buying is the decorated automatic build: a 39 mm case with the correct thin profile, an engine-turned guilloché dial rather than a printed grid, blued steel Breguet hands, and a movement that looks finished through the sapphire back. Cheaper builds fail where a Classique cannot hide anything, which is the dial and the case side. Four criteria decide the purchase: case and lug construction, dial execution, hand finishing, and whether the subsidiary displays function the way the reference does. There are no scores or prices here, because a listing's quality is something you verify, not something a page can measure for you.

Why a Classique is harder to copy than a dive watch

A dive watch can bury sloppy work behind a bezel, a bracelet, and a dial full of luminous plots. A Classique has none of that cover. The dial is large, silvered, and lightly detailed, and the case is thin, so a half millimeter of extra height or a soft polished edge reads at arm's length.

  • Engine-turned guilloché. Breguet cuts dials on a rose engine in overlapping patterns such as clous de Paris, barleycorn, and sunburst. Replicas stamp the pattern into a blank, print it, or cut it shallow with a CNC. Under raking light, stamped work looks flat and repeats on a visible grid with a seam at the center.
  • Breguet hands. Blued steel, thin, with the eccentric ring near the tip. Cheap hands are stamped and painted blue, and the paint shifts purple in daylight while the edges stay blunt.
  • Soldered lugs. Breguet welds the lugs to the caseband and uses screw bars. Spring bars and drilled lug holes are an easy tell for anyone who handles the watch.
  • Fluted caseband. The vertical fluting is fine and even on the original. A wavy or shallow flute line means the case was cast and finished lightly, not machined.

Movement tier: what sits behind the sapphire back

Tier 1: quartz with a decorative plate

  • Pros: thin case is easy to fake, cheap to run, accurate over weeks without winding.
  • Cons: ticking seconds hand, a rotor and bridges that are decoration rather than machinery, no power reserve function, nothing to show at a dinner table.

Tier 2: budget automatic

  • Pros: sweeping seconds, a real mainspring and gear train, lower cost than the top tier, serviceable by a general watchmaker.
  • Cons: often thicker than the reference, decoration applied as a glued plate, coarse dial finishing, hands that are the wrong length or the wrong blue.

Tier 3: decorated automatic (the pick)

  • Pros: case dimensions that track the reference, a movement you can look at without wincing, dial and hands that survive a loupe, and a subsidiary seconds display in the correct position.
  • Cons: the highest cost of the three, harder to service because parts are not cataloged, and still a counterfeit with the same legal exposure as the cheap ones.

Checks to run before you accept the watch

  1. Measure case thickness with calipers and compare it to the reference you are matching.
  2. Tilt the dial under a desk lamp and look for flat, repeating guilloché that stops short of the center.
  3. Check hand color in daylight and in shade; blued steel changes tone, paint does not.
  4. Confirm welded lugs and screw bars, then look at the fluting for straight, even lines.
  5. Watch the subsidiary seconds for a smooth sweep and check whether it hacks when you pull the crown.
  6. If the dial carries a power reserve sector, wind the watch and confirm the sector travels as the mainspring runs down over two or three days.
  7. Read the caseback engraving with a loupe for depth, spelling, and a reference and serial that match the dial.
  8. Wind and set the crown; grit or wobble means the stem and keyless work are rough.

Which build suits which buyer

If the watch lives under a shirt cuff and nobody handles it, Tier 2 does the job and leaves money for a second piece. If you display it, photograph it, or hand it to friends, Tier 3 is the only tier that holds up, because the caseback view and the dial are the two things people look at. If the caseback is sapphire and you still choose quartz, you have bought a problem with a nice dial on it.

Before you pay

  • Request dated photos of the actual watch, not catalog images, and a short video of the seconds hand running.
  • Ask for movement photos with the caseback off and a timegrapher readout if the seller has one.
  • Get the return window and the shipping method in writing, since seizure risk falls on the buyer in most cases.

The legal line you should not skip

Counterfeit watches are illegal to import into the United States, and shipments are subject to seizure and forfeiture, which means a buyer can lose both the watch and the money. Selling one carries additional exposure. That risk does not change with the quality tier, so decide with the law in view and not only with the dial in view.
