A Breguet Classique moon phase copy watch is a replica of Breguet's gold dress models, most often the Classique 7787 and the Classique 7337. It reproduces the fluted caseband, the guilloché dial, the blued Breguet hands, and the moon phase display that follows the lunar month. Prices run from about $90 for a basic build to $600 and up for a top-tier copy with a Swiss or Swiss-clone movement.
Fake Breguet Classique Moon Phase Watch: A Comprehensive Guide
What does the original Breguet Classique moon phase look like?
The real watch is a 39 mm gold dress piece with a silver dial turned on a rose engine, a fluted (coin-edge) caseband, and welded lugs. Breguet fits it with a self-winding calibre and a moon phase display, and retail sits in the five-figure range. That price gap is the whole reason copies exist.

Details a good copy needs to match
- Case: 39 mm across, about 10 mm thick, with fluted sides and curved welded lugs.
- Dial: fine guilloché pattern, Breguet numerals, and the small secret signature hidden in the engraving.
- Hands: blued steel with the eccentric hollow tip Breguet is known for.
- Moon phase: a dark blue disc with a silver moon face and stars, seen through an aperture or a small subdial.
- Caseback: sapphire display back, engraved reference and serial on the rim.
Does the moon phase work on a copy?
On better copies, yes. The moon disc advances on a 29.5-day cycle driven by a 59-tooth wheel, so it tracks the real lunar month within a day or two per year. Cheap versions mount a disc that spins once every 24 hours, which is wrong and visible within a day of wear.
Test it in the shop. Note the moon position, come back 24 hours later, and check how far it moved. A correct copy moves about one fifty-ninth of a full turn; a fake one completes the whole circle.

What separates the price tiers?
Under $150
Mineral glass, a stamped or printed dial, plated hands, a decorative moon disc, and a stiff strap. Fine as a costume piece, weak as a replica.
$180 to $350
This is the sweet spot for most buyers. Sapphire crystal, machine-turned guilloché, a working moon phase, and an A2813 or 2824 clone movement. The case shape sits close to the original and the dial reads well at arm's length.
$400 and up
Closer to the real thing: real blued steel hands, cleaner guilloché, an engraved caseback with the correct reference, a clone ETA 2824 or a Sellita, and an alligator or calf strap. This is the tier that looks right in the hand as well as in photos.
How do you spot a weak copy?
- The dial pattern looks flat or wavy instead of crisp and even.
- Hands are painted blue rather than heat-blued steel, so the color reads purple or dull.
- Moon disc printing bleeds, or the stars sit off center.
- Caseband fluting is shallow and the crown sits proud of the case.
- Lugs are cast with the case instead of welded, which changes the profile.
- Caseback engraving is laser-faint or carries the wrong reference number.
Which movement is inside?
Most copies use one of four movements. Ask the seller and look at photos of the caseback before you pay.
- A2813 and the 2813 family: cheap, 21,600 vph, rough finish, but replacement parts cost little.
- 2824 clone: 28,800 vph, hacks and hand-winds, the best balance of price and feel.
- Seagull ST21 or ST18: Chinese-made, smoother finishing than the clones.
- ETA or Sellita: found in the top tier, serviceable by any watchmaker.
How do you set the moon phase?
- Set the time and date first, if the model has a date.
- Look up the current moon age in days since the last new moon.
- Use the corrector pusher on the case side, or the crown position the maker lists, and press once for each day of moon age.
- Stop when the moon sits where it should for today. On a working copy this takes 1 to 29 presses.
Keep away from the corrector between about 9 pm and 3 am if the watch also has a date, since the gear train is engaged then.
Frequently asked questions
Can a watchmaker tell it is a copy?
Yes, on a bench with a loupe. Telltales include the movement finish, the depth of the caseback engraving, the guilloché inside the moon aperture, and the polish on the lugs. At arm's length, a mid-tier or top-tier copy passes.
Is a copy water resistant?
Treat 30 m or 50 m ratings as splash protection only. Gaskets on replicas are the first thing to fail, so keep the watch away from showers, pools, and the sea.
How long will it last?
With an A2813, expect a few years before a service or a movement swap. A clone 2824 or a Sellita can run for years and is worth servicing.
Does a 39 mm dress watch fit most wrists?
Yes. At 39 mm with thin lugs and about 10 mm of thickness, it slips under a cuff on wrists from about 6.5 to 7.5 inches. Smaller wrists should try one on before buying.
Buying checklist
- Confirm the case measures 39 mm and the thickness stays near 10 mm.
- Ask for a video of the moon phase over 24 hours, not just a still photo.
- Check that the hands are blued steel, not painted.
- Request close-ups of the dial guilloché and the moon disc printing.
- Confirm the movement model and its beat rate.
- Compare the caseback engraving against the correct reference.
- Ask about strap material and buckle type.
Spend in the $250 to $400 band if you want a watch that survives daily wear and looks right on the wrist. Below that, the moon phase is often the first thing to go.
