Short answer

I could not verify "Omega 3604" as an Omega reference number or an Omega caliber in Omega's published material. In replica listings, 3604 acts as a seller SKU. A "copy" is a third-party watch that copies the look of an Omega model. It carries no Omega warranty, no Omega service history, and no Omega resale value.

What the number points to in a listing

  • A product code, not a model name. Two sellers can use 3604 for two different watches.
  • A dial layout copied from a real Omega line, most often Seamaster, Speedmaster, or Constellation.
  • A spec list with case size, movement, crystal, and water resistance.

Copy, homage, counterfeit

An homage uses a similar case shape and dial layout under the maker's own brand name. A counterfeit carries the Omega name, logo, and reference text without a license. Sellers use "copy" for both. The legal difference matters. Unauthorized use of the Omega trademark can lead to seizure at import and civil claims.

What to check before buying

  1. Case diameter in millimeters and lug width. Genuine Seamaster and Speedmaster cases have set dimensions.
  2. Movement: model number, jewel count, power reserve, and country of origin.
  3. Crystal type: sapphire or mineral glass.
  4. Water resistance rating, if the listing states one.
  5. Return window, payment method, and tracking.

Price range

Replica Omega watches on seller sites often list between $150 and $500. Genuine Omega automatic watches list in the thousands. The movement accounts for most of the gap. Most $200 replicas do not use a Swiss automatic movement.

Bottom line

Treat 3604 as a seller code. Ask for the movement name, case size, and crystal type in writing. If the listing uses the Omega name and logo, the item is a counterfeit, not an homage.
