The short answer
A fake Breguet ultra thin is a counterfeit copy of a slim Breguet Classique, the kind of watch that slides under a cuff and measures roughly 5 to 7 mm from crystal to caseback. Thinness is the hardest single thing to copy in watchmaking. Most replicas get the dial roughly right and then give themselves away in profile, in the caseback, or under calipers.

Why the real ones are thin
Breguet builds these watches around movements designed for the case, not adapted to it. The mainplate, bridges, and rotor (when there is one) are stacked tight. The crystal is thin, the dial is thin, and the caseback is shaped to hug the wrist. Remove any one of those decisions and the watch grows a millimeter or two, which is exactly what happens with most fakes.

The tiers you will run into
- Budget tier, under about $150. Usually quartz or a low-grade automatic. Case thickness lands at 9 to 11 mm. The dial is printed, the guilloche is a flat pattern, and the Breguet numerals have the wrong weight.
- Mid tier, roughly $250 to $500. Clone automatic movements. Better dial printing and stamped guilloche, but still 8 to 9 mm thick, with a caseback that bulges or a crystal that sits proud.
- Upper tier, $600 and up. Sellers call these super clones. Some use modified or custom slim movements and get to 6.5 to 7.5 mm. Finishing is closer, but the last half millimeter is where the money and the engineering live.
Prices move around, and the tier labels are marketing more than standards. Treat any specific number as a starting point, not a rule.

What to inspect if you are serious
I look at measurements before photos. Ask for caliper shots at the crystal and at the center of the caseback, taken on the actual watch. A seller who only sends rendered images or factory stock photos is telling you something.
- Profile and caseback. Real Breguet casebacks have crisp, deep engraving. Fakes usually show shallow laser etching and softer edges.
- Guilloche. Hand-turned patterns have a slight irregularity and catch light in a way stamped patterns do not. Look at the edges of the pattern, where stamping goes mushy.
- Hands. Breguet hands are blued steel with a polished ring near the tip. Many fakes use painted or PVD hands that look flat.
- Dial print. Check the weight of the logo, the spacing of the numerals, and the secret signature. Reprints tend to be heavier and less even.
- Weight and sound. A thin watch still has a dense feel. A hollow tick or a rattling rotor is a bad sign.
Red flags worth taking seriously
A "1:1 super clone" label with a price under $300, no measurement photos, no caseback photos, pressure to pay outside a trackable method, and claims of genuine Swiss manufacturing on a watch that costs less than a service on the real thing. Water resistance claims on thin fakes are usually fiction. Do not swim with one.
The part most guides skip
Counterfeit watches are illegal to import into the United States, and customs officers seize them routinely. There is no warranty, no parts support, and resale value near zero. A watchmaker may refuse to service it, and the movement inside is often a generic clone with no documentation.
Bottom line
If you want the ultra-thin Breguet look, this is the worst category to fake and the easiest to fact-check with a pair of calipers. Know the thickness of the real reference, ask for a measurement, and decide with that number in front of you. If the number is wrong, nothing else on the watch matters.
