There is no meaningful replica of the Omega calibre 151. The 151 is a vintage hand-wound movement from the early 1960s, and replica factories concentrate on modern, high-demand references like the Seamaster 300M, Speedmaster Professional, Aqua Terra and Constellation. A genuine 1960s three-hand Omega often sells for a few hundred dollars, so tooling a counterfeit version would cost more than the real watch is worth.
What does "Omega 151" actually mean?
In collector language, 151 points to a small manual-wind Omega movement used in simple dress watches of the early 1960s. It is a time-only calibre, so it carries none of the complications that cloners like to advertise.

The number also shows up in Omega case reference stamps that begin with 151, and sellers sometimes use it loosely for any slim vintage Omega. That ambiguity is why so many buyers ask the same question and get a different answer each time.
Do super clone factories make an Omega 151?
No. The counterfeit industry is driven by margin and demand, and both point at current models still sold in boutiques. A hand-wound 60-year-old calibre has a tiny buyer pool and almost no brand-new price to undercut.

Even the better replica makers, who do produce convincing modern Omega and Rolex copies, publish catalogues built around Submariner, Datejust, Seamaster and Speedmaster lines. A vintage manual-wind calibre does not appear there, and it is not on any roadmap.
So what fake will you actually run into?
The risk with a 151 is not a super clone. It is the franken watch: a reprinted or aftermarket dial, mismatched hands, or a generic movement dropped into a genuine-looking case and sold as all-original.
Online marketplaces are full of these assembled pieces, often described as "serviced" or "recently restored" with no movement photograph. A redialled vintage Omega can look convincing in a phone photo and obvious in daylight.
How can you check a vintage Omega before paying?
- Ask for a clear, straight-on photo of the movement and compare the calibre stamp to published references.
- Match the caseback reference number to the dial layout and hand style for that reference.
- Request Omega's archive extract, which confirms the movement and case a watch left the factory with.
- Walk away from any listing that hides the serial, the caseback interior, or the movement.
Is buying a replica Omega legal?
In the United States, trafficking in counterfeit goods is illegal, and counterfeit watches are routinely seized by Customs and Border Protection at import. Buyers risk losing both the money and the watch, and sellers face far more serious exposure.
That legal reality is another reason a niche vintage copy has never been produced at scale. The modern super clone market exists despite enforcement, not because the risk is small.
Common questions about the Omega 151
How much does a genuine Omega 151 cost?
A clean, running example in a plain steel case usually trades in the low hundreds to roughly a thousand dollars depending on condition, box and paperwork. Restored or franken examples sit at the bottom of that range.
Where would you see "151" on an actual watch?
It appears as a calibre number on the movement bridge and as a prefix inside some caseback reference stamps. The two are not the same thing, so confirm which one a seller means.
Should you buy a cheap "vintage Omega" from a marketplace?
Only with movement photos, a caseback shot and a return window. At that price tier the odds of a redial or a mismatched movement are high, and a returned watch is far cheaper than a bad one.
