Short answer
A "De Trèville" copy watch is a replica of the Omega De Ville line. De Trèville is a spelling drift of De Ville, and most copies sit on the De Ville Trésor model. Omega does not make these watches and does not sell them. A copy carries a quartz or low-grade automatic movement, a steel case with gold plating, and a printed dial. A real De Ville Trésor uses an Omega Co-Axial Master Chronometer movement, a 40 mm case, and a 72-hour power reserve.
What the real De Ville Trésor has
- Case size: 40 mm on the standard model.
- Case metal: 18k Sedna gold, yellow gold, or stainless steel, by reference.
- Movement: manual-wind Co-Axial Master Chronometer, 72-hour power reserve.
- Water resistance: 30 m.
- Certification: METAS Master Chronometer card with the movement number.
- Dial: domed, with small seconds at 6 o'clock on most references.
Where copies differ
- Movement: quartz, or an unbranded automatic with a plain rotor and no Co-Axial escapement.
- Magnetism: the real movement runs inside a 15,000 gauss field. Copies gain or stop near a phone magnet.
- Case: 316L steel with plating measured in microns. Plating rubs off at the lugs and crown.
- Dial: printed logo, wrong type weight, flat surface instead of a domed one.
- Caseback: shallow engraving, and a reference number that does not match Omega records.
Prices
Copy prices run from about $60 to $400. The range tracks the movement: quartz at the bottom, a Miyota or Seagull automatic at the top. Resale value is near zero. Genuine De Ville Trésor prices run from the mid four figures in steel to above $12,000 in gold. Omega publishes current retail prices on its own site.

Legal status in the US
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. A first offense carries up to 10 years in prison and a $2 million fine for an individual. US Customs and Border Protection seizes counterfeit shipments and destroys them. The OECD put counterfeit and pirated goods at 3.3 percent of world trade in its 2019 report.
Checks before you buy
- Ask for the METAS card and the movement number. Copies do not have one.
- Look through the sapphire caseback. A real Trésor shows Geneva stripes, polished bevels, and a balance that runs at 3.5 Hz.
- Check the reference number on the caseback against the Omega database.
- Compare the case thickness and the dial dome against published specs. Copies run thicker and flatter.
