Short answer
No Omega catalog lists a Constellation with the reference 151.10.41. The number does not fit any documented Omega reference format. Listings that use this string are seller labels, not factory references. Omega has not published a Constellation with that code.
What Omega reference numbers look like
Current Omega references use a digit code in fixed positions. One example is 123.10.35.20.01.001, where each block marks case size, material, movement and dial. Vintage Constellation models from the 1950s through the 1970s use five or six digits, such as 168.005 or 14902. A three-part number with two decimal points matches neither pattern.
Why the string shows up in search
Replica sellers invent or recycle number strings to make a listing look technical. Buyers copy the number into a search bar, then repeat it on forums, marketplace titles and video captions. That path explains a number that no manufacturer documents.
Constellation references that get copied most
- 168.005, a 1950s pie-pan dial model
- 168.017, a 1960s date model
- 278.002, a 1950s chronometer
- 123.10.35.20.01.001, a current 35 mm model
How to check any Constellation reference
- Read the caseback and the movement. Omega stamps both with the reference and a serial.
- Compare the number to an Omega service record or the brand's own database.
- Check the dial font, the crown logo and the date window position.
- Weigh the case. Counterfeit cases use lighter alloys.
- Ask for a movement photo. Replica movements show unmarked bridges or a battery.
Legal status in the United States
Trafficking in counterfeit goods is a federal crime under 18 U.S.C. 2320. A first offense carries up to 10 years in prison; repeat offenses carry up to 20 years. U.S. Customs and Border Protection seizes counterfeit watches at ports of entry and destroys them. Buyers can lose the item and the money paid.
Note on the Rolex mix-up
Constellation is an Omega line. Rolex lines are Datejust, Submariner, GMT-Master, Day-Date, Explorer and Oyster Perpetual. A listing that pairs the Constellation name with a Rolex model name is a label error or a sales tactic.
What is unknown
No public record ties the string 151.10.41 to a specific seller, factory or model. Treat it as unverified until a documented source matches it.
