Answer first

424.10.40.20.02.001 is an Omega De Ville Trésor reference. The genuine watch has a 40 mm stainless steel case, a silver dial, an Omega 2500 Co-Axial automatic movement, and a leather strap. Omega does not list this reference in the current catalog. Replica sellers in China list it at $80 to $400. Importing a counterfeit watch into the United States is illegal. Customs can seize the parcel.

Reading the reference number

Omega builds codes in blocks. 424 is the De Ville family. 10 is the case metal, stainless steel. 40 is the case diameter, 40 mm. 20 is the movement block, the Co-Axial automatic. 02 is the dial, silver. 001 is the first version of the reference. Omega does not print one data sheet for every code. Check the caseback, the warranty card, and the serial before you pay.

Genuine specs, as listed

  • Case: stainless steel, 40 mm
  • Movement: Omega calibre 2500 Co-Axial automatic
  • Beat rate: 25,200 vibrations per hour
  • Crystal: sapphire
  • Dial: silver with applied markers
  • Strap: leather with a steel buckle
  • Water resistance: 30 m on most De Ville dress models

Omega's Extract of the Archives service confirms the build date and reference for a fee. Production years for this code are not published in one place. Ask the seller for the serial on the movement and on the caseback.

Replica tiers and prices

Listings for this reference split into three tiers. Quartz versions run $30 to $80. Mid-tier automatic versions with a Miyota or Seagull movement run $120 to $250. Top-tier versions with a cloned 2500 movement and a decorated rotor run $250 to $400. Shipping from China adds $20 to $50. Sellers take bank transfer, crypto, or gift cards. Refunds are rare.

Checks before payment

  1. Ask for dated photos of the caseback, crown, clasp, and movement.
  2. Compare case thickness. The genuine case measures about 10 mm. Most replicas add 1 mm to 2 mm.
  3. Check beat rate. The 2500 Co-Axial runs at 25,200 vibrations per hour. A Miyota 9015 runs at 28,800. A timegrapher shows the gap.
  4. Check dial print at 10x. Replica print shows soft edges on the De Ville text.
  5. Compare the buckle and strap stitching to catalog photos. Strap codes sit on the underside.

Secondary market for the real watch

Used steel De Ville Trésor models sit between $1,500 and $3,000 on auction sites and dealer listings. Box, papers, and service history move the price by several hundred dollars. A service at Omega adds to the total. Parts for the 2500 movement stay in supply.

US customs and law

19 U.S.C. 1526 covers counterfeit imports. Customs and Border Protection can seize and destroy a counterfeit watch. The buyer receives a seizure notice. The seller keeps the money. A false customs declaration on the parcel does not change the law.
