A fake De Ville Trésor 40mm is a counterfeited copy of Omega's thin hand-wound dress watch in its 40 mm case size. Genuine steel models sell for about $5,000 to $6,000 at retail, while replicas cost between $80 and $400. That price gap comes from three things: the movement, the case and dial finishing, and the fact that counterfeits are illegal to sell in most countries.
What Is the Omega De Ville Trésor 40mm?
The Trésor is Omega's classic dress watch line, and the 40 mm version is the largest of the family. It pairs a slim polished case with a domed dial and a hand-wound Master Chronometer movement. Omega offers it in stainless steel, solid gold, and two-tone builds, with diamond-set bezels on some references.
Key specs of the genuine watch
- Case: 40 mm wide and about 10 to 11 mm thick, with a polished bezel and lugs that curve toward the wrist.
- Movement: Omega calibre 8928 or 8929, a manual-wind Co-Axial with a silicon balance spring, a 72-hour power reserve, and METAS Master Chronometer certification.
- Dial: Domed, with applied Roman or baton markers, a small seconds subdial at 6 o'clock on some versions, and thin leaf-shaped hands.
- Crystal and caseback: Domed sapphire up front and a sapphire display back with anti-reflective coating inside.
- Strap: Alligator leather on a polished pin buckle for steel models.
How Do Replica Trésor 40mm Watches Compare?
Replica makers sell the 40 mm Trésor in several grades, and the differences between them matter more than the price tags suggest. A cheap copy can look close in photos but falls apart in the hand. A higher-grade copy gets the case profile right and still misses on movement and finishing.
Movement
No replica runs an Omega calibre 8929. Most use a Chinese hand-wound movement or a decorated automatic, and a few use a Miyota-based unit. The tell is the caseback view. The real movement shows Geneva stripes, blued screws, and a balance bridge with engravings you can read under a loupe.
Case and dial
Case thickness is the first thing that gives a replica away. Genuine Trésor cases are thin, and counterfeits run thicker to fit a taller movement. Dial printing on copies looks flat, and the small seconds hand often moves in a jerky motion instead of sweeping.
Strap and clasp
Replica straps use embossed cowhide or low-grade leather instead of alligator, and the buckle lacks crisp Omega engraving. The tang, the spring bars, and the stitching are the easiest places to cut cost, so that is where counterfeiters cut first.
How Can You Spot a Fake De Ville Trésor 40mm?
- Measure the case thickness. A 40 mm Trésor that runs past 11.5 mm with the crystal is not genuine.
- Look at the crown. The Omega symbol should sit level and sharp, not stamped off-center.
- Watch the small seconds hand. Real manual-wind Omegas beat with a smooth, steady motion.
- Read the caseback engraving. Reference numbers, the Master Chronometer text, and the movement finish should match the model.
- Weigh it. Solid gold and steel cases have a heft that cheap alloys do not.
- Ask for the METAS card. Every Master Chronometer ships with a test certificate tied to the serial number.
What Are the Risks of Buying a Fake Watch?
Counterfeit watches are illegal to import and sell in the United States under trademark law. US Customs and Border Protection seizes counterfeit watches and other trademarked goods at ports every year, and buyers can lose both the item and the money.
- No Omega warranty, service, or parts support at any authorized center.
- Repairs are hard. Independent watchmakers often refuse to work on counterfeit movements.
- Resale value sits near zero, and selling a counterfeit is a separate legal offense.
- Water resistance claims are unverified. A copy rated for 50 meters may leak in the shower.
FAQ
How much does a fake De Ville Trésor 40mm cost?
Replica listings run from about $80 for a basic quartz or cheap mechanical copy to $400 for a higher-grade automatic. Some sellers ask more than $500 by claiming Swiss-made parts, but that label on a counterfeit is marketing, not fact.
Is a replica Trésor the same size as the real one?
Copies often measure 40 mm across, but case thickness and lug shape differ. That is why a replica can wear bigger on the wrist than the genuine watch even when the diameter matches.
Can a jeweler tell a fake Trésor from a real one?
Yes, and it takes seconds in most cases. A watchmaker checks the movement finish through the caseback, the crown logo, and the dial printing. Solid gold models also show different hallmarks than plated copies.
Do replica watches hold value?
No. Genuine Omega watches keep a large share of their retail price on the pre-owned market. Counterfeits trade at a fraction of what buyers pay and are hard to sell at all.
What Should You Do Instead?
A pre-owned genuine Trésor or another Omega dress reference costs more than a replica, but it holds value, can be serviced, and comes with a real history. Buyers who want the look on a smaller budget can also look at entry-level Swiss dress watches from Tissot, Longines, or Junghans. Those brands sell thin hand-wound and automatic models for a few hundred dollars, and every one of them is legal to own, resell, and repair.
