Quick Answer

The Omega De Ville Trésor 2023 is a dress watch. Steel cases measure 40 mm across. The movement is a manual-wind Master Chronometer calibre with a 72-hour power reserve. Counterfeit versions copy the dial layout and the case shape. They do not copy the movement, the case metal or the METAS certification card.

Genuine Specs to Compare

  • Case size: 40 mm for most 2023 references. A 36 mm size exists for some dials.
  • Case metal: stainless steel or Sedna 18K gold.
  • Movement: manual wind, Co-Axial escapement, 72-hour power reserve in the small-seconds version.
  • Certification: METAS Master Chronometer. Magnetic resistance to 15,000 gauss.
  • Dial: domed. Applied indexes. Small seconds subdial at 6 o'clock.
  • US retail in 2023: steel references sat in the high four figures. Gold references sat in the low five figures. Omega does not publish one global price.

Where Fakes Fail

  • Movement. A quartz or basic automatic movement sits under the caseback. No Co-Axial escapement. No 72-hour reserve.
  • Metal. Brass or plated steel. Weight runs low against a genuine case.
  • Markers. Printed, not applied. Edges look flat.
  • Caseback. Engraving is shallow. Fonts differ. Serial numbers do not match the movement number.
  • Paperwork. No Master Chronometer card. No serial match between card and watch.
  • Price. A Co-Axial manual-wind movement costs more than a complete fake. A 2023 Trésor at a few hundred dollars is not genuine.

Checks Before You Pay

  1. Ask for the Master Chronometer card and the serial number. The numbers must match the movement.
  2. Compare the caseback engraving to photos on the Omega site.
  3. Have a watchmaker open the case. The movement finish and the calibre number settle the question.
  4. Weigh the watch. A solid gold case weighs more than a plated one.
  5. Walk away from sellers who block an inspection.
