Answer first: Omega does not sell a watch called the "Omega 151." Listings that pair that phrase with "replica," "super clone," "1:1 Swiss," or "AAA grade" are offering a counterfeit. No authorized dealer stocks it, no factory warranty covers it, and US trademark law treats the item as infringing merchandise that customs officers can seize and destroy. If the goal is the look of a Swiss sports watch at replica-ad prices, the reliable route is a legitimate watch from an established brand, or a pre-owned genuine Omega bought from a seller who documents the serial number and case reference.

Why "Omega 151" appears in search results

Reference numbers get scraped from auction archives, parts catalogs, and forum posts, then recycled into ad copy for counterfeit sellers. A fragment like "151" can be a piece of a longer vintage reference, a case-code abbreviation, or pure invention. Omega reference numbers are specific and long (for example, the Speedmaster family uses full numeric references plus a suffix), and a short number alone authenticates nothing. Any page that treats "151" as a model name is either guessing or selling.

What you give up with a counterfeit

  • Upside claimed by sellers: low upfront price, and a dial that reads correctly from across a room.
  • Downside: no manufacturer service, no parts network, and no warranty.
  • Downside: water resistance claims are unverified, so swimming or showering can ruin the watch.
  • Downside: resale value near zero, plus possible seizure in transit and chargeback disputes that go nowhere.
  • Downside: counterfeit watches fund organized crime and often ship with no consumer protection at all.

Use case call: if you want a watch to wear hard, travel with, and pass to someone else later, a counterfeit fails on every count.

Red flags in a counterfeit Omega listing

  1. Price far below the market for the real reference, with no serial number shown.
  2. Photos with mismatched dial, hand, and bezel details, or stock images reused across sellers.
  3. Copy that avoids the word "fake" and leans on "clone," "mirror," or "same factory."
  4. No physical address, no return policy, and payment only by peer-to-peer transfer.
  5. Pressure to decide fast, usually through a countdown timer or a "last one" message.

Legitimate alternatives at counterfeit prices

Tissot PRX Powermatic 80

Pros: integrated-bracelet design that reads as a luxury sports watch, Swiss automatic movement, real warranty, easy service. Cons: no Omega badge, and the finishing is simpler than a Speedmaster. Best for: a first serious automatic on a modest budget.

Hamilton Khaki Field Auto

Pros: military-adjacent styling, solid movement, wide size range, strong resale for the money. Cons: restrained looks that skip the flashy case shapes. Best for: daily wear and travel.

Seiko Presage or Alpinist

Pros: excellent dial work, in-house movements, deep service network. Cons: Japanese rather than Swiss, and some references run thick. Best for: buyers who care about finishing more than a logo.

If you want the real Speedmaster look

Buy pre-owned from a dealer who provides the reference number, serial, and service history, and confirm the numbers match the case and movement. A genuine watch with a documented past costs more than a counterfeit and holds most of that value when you sell.

Bottom line

The "Omega 151" search term describes a counterfeit, not a model. Skip the listings, buy a legitimate watch at the same price, and the watch you wear will keep time, keep value, and stay legal.
