A fake Omega De Ville Trésor 40mm 424 is a counterfeit copy of Omega's De Ville Trésor 40mm, the automatic dress watch whose reference numbers begin with 424. It is not a variation, a factory second, or a "first copy." Under US law it is an infringing counterfeit, and it carries none of the movement, materials, warranty coverage, or resale value of the genuine watch.
What is the real Omega De Ville Trésor 40mm?
The Trésor is Omega's slim dress line, and the 40mm version is its core modern men's size. Genuine examples run an Omega in-house Master Co-Axial automatic movement, visible through a sapphire caseback.
Reference numbers in the family start with 424, followed by codes for case metal, diameter, and dial. A steel Trésor 40mm might read 424.13.40.20.02.001, while gold versions carry different metal codes in the same 424 block.
- Case: polished stainless steel or 18k gold, roughly 40mm wide and under 11mm thick
- Dial: domed, with applied indices, polished hands, and the "Trésor" script
- Movement: Omega Co-Axial automatic with a silicon balance spring
- Crystal: domed sapphire with anti-reflective treatment on both sides
- Warranty: five years, honored only with valid papers from an authorized dealer
How do you spot a fake De Ville Trésor 40mm 424?
- Movement. A genuine Trésor shows a finished Omega movement with Co-Axial escapement through the caseback. Counterfeits often hide an unbranded automatic or quartz movement behind a solid back or a poorly printed rotor.
- Case finishing. Real Trésor cases have crisp transitions between brushed and polished surfaces. Fakes show blurred edges, wrong weight, and plating that wears through to base metal.
- Dial printing. Look at the Trésor script, the Omega symbol, and the date window. Counterfeit text is usually thicker, misaligned, or printed rather than applied.
- Engravings and numbers. The reference and serial numbers on the caseback should match the paperwork and Omega's service records.
- Price. Genuine 40mm Trésor models sell in the thousands of dollars, with gold versions far higher. A "new" one at a fraction of that is counterfeit.
- Verification. An Omega boutique or authorized service center can confirm the serial number and reference.
Why are "first copy" or replica Trésor watches risky?
Counterfeit watches are illegal to import into the United States, and US Customs and Border Protection can seize them at the border. Trafficking in counterfeit goods is a federal offense under 18 U.S.C. 2320, and repeat sellers face criminal penalties.
Buyers also lose everything a real watch provides: no manufacturer service, no parts availability, no warranty, and effectively no resale value. Counterfeit sellers frequently reuse stolen product photos and disappear after payment.
Is buying a fake Omega De Ville Trésor legal in the US?
No. Selling, trafficking, or importing counterfeit goods violates US trademark and customs law, and shipments are subject to seizure and destruction. Buying one does not create any legal ownership of the Omega trademark or design.
What should buyers do instead?
Shop an authorized Omega dealer, or buy pre-owned from a reputable dealer or auction house with box, papers, and a verifiable serial number. A pre-owned genuine Trésor holds value and can be serviced for decades, which no counterfeit can match.
