A counterfeit Seamaster 300M 291 is a replica of the Omega Seamaster Diver 300M sold under a seller or catalog code, not an official Omega reference number. Omega builds Seamaster references in a long numeric format (for example 210.30.42.20.03.001), so a short string like 291 points to a listing title rather than to anything the brand has issued.
Why the number 291 shows up in fake listings
Replica sellers label their stock with short codes so buyers can track batches, factories, and revisions between orders. Those codes get copied into marketplace titles, forum threads, and social posts, which is how a counterfeit Seamaster 300M 291 becomes a search term. The number is a seller convention. It carries no meaning in Omega's reference system, and it will not appear on a genuine warranty card, hang tag, or caseback.

That matters for buyers because a listing built around an invented code usually signals a replica catalog rather than a reseller with a real watch in hand.

How to tell a counterfeit Seamaster 300M from the real watch
The Seamaster Diver 300M has several features that replicas struggle to reproduce at full fidelity. Inspect these points before money changes hands.

- Dial and hands. Genuine applied markers sit flush with even lume fill. Replicas often show uneven paint edges, slightly misaligned indices, or hands that sit too high above the dial.
- Wave dial pattern. The laser-engraved waves should be crisp and consistent across the whole dial, not shallow near the edges or visibly printed.
- Helium escape valve. On the genuine watch the valve at 10 o'clock threads smoothly and sits flush with the case. Fakes frequently bind, sit proud, or are purely decorative.
- Bezel action. A real diving bezel clicks with firm, even detents and aligns its triangle to 12 o'clock. Loose, gritty, or misaligned bezels are a common replica fault.
- Caseback engraving. The seahorse medallion and surrounding text are deep and sharply defined on the real piece. Laser-etched fakes look flat under angled light.
- Weight and finishing. Replicas often feel light or show sharp brushing transitions at the lugs and case flanks.
- Documentation. Serial numbers should match across the case, warranty card, and paperwork, and the card should carry a date and dealer stamp.
Movement and caseback checks
A counterfeit Seamaster 300M 291 usually runs a third-party automatic or a quartz movement hidden behind a closed caseback. A watchmaker can confirm the movement family in minutes under a loupe, and a genuine co-axial caliber will not match the bridges or rotor text seen on replica movements. Ask for a timed movement photo with the caseback removed, or have the watch inspected before purchase.
What you risk when you buy a counterfeit
- No water resistance. Replica cases are rarely pressure tested, so swimming or diving can flood the movement.
- No service support. Omega service centers decline counterfeit watches, and independent watchmakers may refuse the work because parts do not interchange.
- No resale value. Replica watches hold little to no resale value and cannot be sold as genuine.
- Materials and safety. Plating, lume, and seal materials on unregulated copies are not tested to watch industry standards.
Legal status in the United States
Selling or trafficking counterfeit goods is illegal in the US, and shipments of counterfeit watches can be seized and destroyed at the border. Buying one for personal use is lower risk than selling one, but the item remains an infringing product with no legal pathway to resale. Anyone who misrepresents a counterfeit Seamaster 300M 291 as genuine invites civil liability and, in trafficking cases, criminal exposure.
If you already own one
Do not sell it as authentic, and do not dive with it. If you plan to move it on, describe it as a replica in the listing and price it accordingly. If the watch arrived misrepresented as genuine, keep the listing screenshots and payment records, then use your card issuer's dispute process.
Is 291 an Omega reference number?
No. Omega reference numbers for the Seamaster Diver 300M are long strings that encode case size, material, and dial color. A three digit code belongs to a seller's catalog.
Can a jeweler tell a fake Seamaster 300M immediately?
A trained watchmaker can usually confirm authenticity in a short bench inspection using the movement, caseback engraving, and bezel action, even without opening the case.
