Quick answer
If the Speedmaster look is what you want, put a legal homage or a pre owned genuine Omega ahead of a counterfeit. Counterfeit watches that carry the Omega name are illegal to import and sell in the United States, they can be seized at the border, and no authorized watchmaker will touch one for service. A homage with a 40 to 42 mm case, a black tachymeter bezel and a three register dial gives you the same wrist presence with a real warranty. If you want the actual watch, remember that 311 is the reference prefix for the modern Moonwatch Professional line, not a single model, so learn the full number before you compare anything.

What the 311 number covers
Omega builds reference numbers in blocks. The 311 prefix covers the current Speedmaster Professional Moonwatch family, and the digits after it describe case material, dial color, crystal type and bracelet. Sellers who quote "311" with nothing after it are describing a range, not a watch. Ask for the complete reference, then match the case size, crystal and movement to the photos they send. A listing that hides the full number is a listing you cannot verify.
What to look for
- Case shape: twisted or lyre style lugs, a case that narrows toward the lugs, and a bezel that sits flush with no gap.
- Bezel insert: black aluminum or ceramic with a tachymeter scale that meets clean at 12 and at 60.
- Dial: three subdials at 3, 6 and 9, correct spacing, straight markers, and a logo that is centered.
- Hands: baton hour and minute hands, a thin chronograph seconds hand, and a counterweight that stays inside the subdial.
- Movement: hand wound chronograph for authenticity, or a quartz if you want low upkeep. Push the chronograph buttons in person when you can.
- Crystal: domed hesalite style or flat sapphire with anti reflective coating on the inside.
- Bracelet: tapering links, solid end links, and a clasp that closes with a firm click.
Parameter bands that work
Case diameter from 39 to 42 mm suits most wrists and keeps the Moonwatch proportions. Lug to lug should stay between 47 and 49 mm so the watch does not overhang. Thickness from 12 to 14 mm clears a shirt cuff without looking like a brick. Lug width lands at 19 or 20 mm, which opens up a large strap selection. Water resistance of 50 m covers daily wear and hand washing; anything rated higher should come with a stated gasket and crown design. A domed crystal and a matte black dial read closer to the original than a high gloss finish.

Pitfalls to avoid
- Stock renders instead of real photos. Ask for a shot of the caseback and the crown side.
- "Swiss made" printed on a dial that was not made in Switzerland. That claim on a counterfeit is a legal problem, not a selling point.
- No service path. A watch with no parts supply becomes a paperweight.
- Water resistance claims with no gasket or pressure test behind them.
- One photo set reused across several references, which signals a drop shipper rather than a seller with stock.
- A price far under the homage market, which points to a thin case, a plastic crystal and a movement that stops.
FAQ
Is a replica Speedmaster 311 legal to buy in the US?
No. Counterfeit goods that copy a protected trademark are illegal to import and to sell, and customs can seize them. Buying one puts the money at risk with no recourse.
Which homage matches the Moonwatch size?
Look for a 40 to 42 mm chronograph with a black tachymeter bezel and subdials at 3, 6 and 9. The Bulova Lunar Pilot and the Seiko Prospex Speedtimer are two common legal options with documented specs and service support.
How should I budget for this style?
Set your ceiling against the pre owned genuine market, then decide how much of the look you need. Homage pricing sits well under genuine pre owned pricing, and a used Omega holds value that a counterfeit never will.
Will a watchmaker service a counterfeit?
Reputable shops decline the work because parts and documentation do not exist. A homage or a genuine watch can be serviced, regulated and pressure tested.
