What "Omega De Tréville clone" means
Omega does not sell a watch named De Tréville. The term blends two real Omega names: De Ville and Trésor. De Ville became a separate Omega line in 1967. Trésor is a dress model inside that line. Omega first used the Trésor name in 1949 for a slim hand-wound movement. The modern De Ville Trésor arrived in 2014 with a 40 mm case. A De Tréville clone search points to a first copy of a De Ville or De Ville Trésor dress watch.
What first copy means in the trade
A first copy is a watch built to match the look of a reference. Omega does not make it. Sellers use the phrase to mark the top grade in a tier list that runs from low-grade replicas to first copy. Two watches can share a dial layout and case size and still differ in movement, case metal, crystal, and strap.
- Case: 316L steel or plated brass. Genuine Trésor uses steel, Sedna gold, Moonshine gold, or Canopus gold.
- Movement: Seagull ST2130, Hangzhou 6300, or Miyota 9015 in mechanical copies. Quartz in the low tier.
- Crystal: sapphire with anti-reflective coating on both faces on the genuine watch.
- Strap: leather with a signed buckle on high grades.
Numbers that separate a copy from the real watch
The De Ville Trésor carries Omega caliber 8928 or 8929 in Master Chronometer versions. Power reserve is 72 hours. The movement resists magnetic fields to 15,000 gauss. It uses a co-axial escapement and a silicon balance spring. METAS certifies each watch through eight tests. A clone movement runs 38 to 42 hours, holds no certification, and has no silicon spring. Case thickness on the 40 mm Trésor is about 10.6 mm. A copy often runs thicker because the movement and the spacer differ.

Checks before you buy
- Measure the case. 40 mm for the Trésor. 39.5 mm or 41 mm for the De Ville Prestige.
- Watch the seconds hand. Quartz ticks once per second. Mechanical sweeps.
- Read the caseback text. Genuine watches list the reference and the caliber.
- Weigh the watch. Gold models run heavier than steel.
Legal note
A first copy is not a genuine Omega. US law 18 U.S.C. § 2320 covers trafficking in counterfeit goods. US Customs and Border Protection seizes counterfeit watches at ports of entry. Resale as genuine carries criminal penalties. Serial numbers and box papers do not prove origin. Unknown: the exact number of first copy watches sold, because no published count exists.
