Short answer

Replica Breguet 7787BR watches live in a small, strange corner of the market. Breguet is not Rolex, so factories build this reference in short runs, and quality swings hard from batch to batch. A good one exists. Most of what you find online is not it. To judge a copy, you first have to understand what the real watch does, because the 7787BR is defined by two complications that replica makers struggle to fake: a moon phase and a power reserve display.

What the genuine watch is working with

The reference is a Classique: 39mm rose gold case, fluted coin-edge caseband, welded lugs, sapphire front and back. Dial variants run from hand-turned guilloché to grand feu enamel, both with Roman numerals, a secret signature, and Breguet's blued steel hands with the eccentric tips. Inside sits caliber 591 DRL, an automatic with moon phase and power reserve, running at 4 Hz with roughly 38 hours of reserve.

Nothing about that list is exotic on its own. The difficulty is that all of it has to work together on a 39mm dial, and the proportions are tight. A dial that is a millimeter off in print placement reads wrong from across a table.

The movement is where the budget goes

Here is the honest part. Almost every replica 7787BR runs a generic or lightly modified automatic, usually based on a 2824-type or a Seagull movement, with a moon phase and power reserve module bolted on top. That module is the whole story.

  • Moon phase: many fakes use a 24-hour day and night disc instead. It rotates once a day, so the moon is in the wrong place most of the time. A real moon phase advances in small steps across about 29.5 days.
  • Power reserve: on a genuine watch the hand sweeps down as the mainspring unwinds. On cheap fakes it is often a fixed decoration that never moves, or it moves in a way that has nothing to do with the actual state of the watch.
  • Rate: the real caliber beats at 28,800 vph. Some replicas run at 21,600. If you cannot see the balance, ask for a timegrapher photo. That single image tells you more than any listing description.

If a seller will not show you the movement or the timing numbers, you are buying a photo, not a watch.

Dial, hands, and case finishing

I look at the dial first, because it is the part you stare at all day. Real guilloché is cut by hand on a rose engine, so the lines have depth and catch light unevenly. Stamped replicas look flat and uniform, and the pattern often fades near the center. On enamel versions, cheap copies have a plastic sheen and slightly rounded printed numerals.

Then the hands. Breguet hands are thin, blued, and finished with a small eccentric ring near the tip. Replicas tend to be thicker, more purple than blue, and blunt at the ends. The caseband fluting is another giveaway. Real fluting is crisp and evenly spaced all the way around. On fakes, the grooves get shallow near the lugs where the tooling ran out of room.

Last, the case itself. A solid rose gold case feels dense and warms to your skin. Plated steel feels lighter and cooler, and the plating wears through first at the lugs and the caseback edge. That wear shows up within months, not years.

Price tiers, roughly

  • $60 to $120: quartz or basic automatic, printed dial, mineral glass, non-working complications. Skip these.
  • $180 to $320: decent automatic, sapphire crystal, better dial print. The moon phase is usually a day and night disc. Fine as a casual wear, not as a 7787.
  • $350 to $650: modified movement, moving power reserve hand, closer dial finishing, proper blued hands. This is the top of the replica market for this reference, and it is still a fraction of the real thing.

What to check before you commit

  1. Ask for dated photos of the actual watch, not stock images. Any seller who cannot do this is reselling.
  2. Request a close-up of the movement and a timegrapher reading.
  3. Ask directly whether the power reserve hand moves when the watch winds down. Get a straight answer in writing.
  4. Confirm the moon phase advances daily rather than once per 24 hours.
  5. Check the crystal material and the caseback fit.
  6. Ask about the lug width so you can fit aftermarket straps.
  7. Read the return window and the warranty wording carefully. Vague terms mean no coverage.

Limits worth accepting upfront

No replica 7787BR is the watch it copies. Water resistance claims are usually marketing, servicing is difficult because parts are not standardized, and resale value is close to nothing. Buy one because you like how it wears and you understand the trade, not because you expect it to behave like a Breguet. If the complications matter to you, save for something with a real moon phase movement. If the look matters more, a mid-tier replica with a moving power reserve and honest dial work is the sweet spot.
