Short answer
A Speedmaster listed with a 329 reference and no Omega documentation is unverified. The word unauthorized means the seller holds no permission from Omega to sell that watch. That covers fakes, frankens, and gray-market pieces. A 329 listing with stock photos, no serial number, and no service record is a fake until proven otherwise.

What the 329 number does and does not prove
Omega reference numbers are catalog keys. They map to a case, a movement, and a dial combination. A number on a hang tag or a plastic card proves nothing. Fakes reuse the same number across many listings. Check the number against the entry on Omega's own site. Then check the engraving on the caseback and the number on the movement. On a genuine watch the three agree.

Caseback and movement
Speedmaster casebacks carry a seahorse medallion or a sapphire display back, depending on the reference. Look at the letter spacing and the depth of the stamp. Fakes show shallow engraving and soft edges. Open the back only with a watchmaker present. The movement should match the reference family: a manual-wind chronograph with the correct bridge shape, finishing, and rotor or no rotor. Photos of a movement that do not match the case are a stop sign.

Dial, hands, and subdials
Compare subdial spacing to a known photo at the same angle. Fakes often misplace the running seconds or the 12-hour totalizer by a fraction of a millimeter. Check the applied logo, the minute track print, and the lume color under daylight. Lume that glows green on a reference that should glow blue is a fake. Hands should sit level with even gaps above the dial.
Papers, serials, and seller claims
Ask for the serial on the caseback, the warranty card, and the original invoice. The digits must match. Ask for a photo of the watch next to today's newspaper. Sellers who refuse are selling something they cannot document. A price far under market for a steel chronograph is a signal, not a deal. Omega does not publish a public serial database, so a dealer or a watchmaker has to verify.
Legal position in the US
Counterfeit watches are illegal to import and to sell. US Customs seizes them at ports, and trademark holders can pursue civil claims. Buying a fake for personal use carries lower risk than reselling one, but resale is where cases get filed. Keep receipts if you buy anything described as aftermarket or modified.
What to confirm before you pay
- Reference number matches the caseback and the movement.
- Serial on the case matches the card.
- Movement photos match the reference.
- Seller offers a return window in writing.
- An independent watchmaker can inspect the watch.
If any item on that list fails, treat the watch as unauthorized and walk away.
