What Is a Speedmaster 311 Replica?
A Speedmaster 311 replica is a copy of an Omega Speedmaster Professional whose nine-digit reference begins with 311, most often the 42 mm hand-wound Moonwatch (311.30.42.30.01.005). The 311 prefix is Omega's internal product code for the modern stainless steel Professional line, not a nickname or a model family. Replica sellers use it as shorthand, so two listings can describe very different watches while both say "311."

What Does the 311 Reference Code Mean?
Omega builds Speedmaster references from blocks of digits: the first group marks the case material and line, the next pair the case diameter, then the caliber family, the dial variant, and the bracelet or strap. A code such as 311.30.42.30.01.005 reads as stainless steel, 42 mm, Moonwatch caliber, dial variant 01, bracelet 005. Replicas rarely match the final digits, and that mismatch is the fastest way to sort a specific listing from a vague one.

Which 311 Models Get Replicated Most?
- 311.30.42.30.01.005: hesalite crystal, solid engraved caseback, the modern Moonwatch.
- 311.30.42.30.01.006: sapphire crystal front and back, known as the sapphire sandwich.
- 311.30.42.30.01.002: sapphire crystal with a solid caseback, an earlier configuration.
All three share the 42 mm case, a 21,600 vph hand-wound chronograph, and the twisted-lug profile, so a replica of any of them has to solve the same problems. Those problems are case thickness, subdial spacing, and hand length.

How Do You Spot a Cheap 311 Replica?
Proportion and finish give a replica away faster than any logo. Work down this list.
- Case thickness: a genuine Professional sits around 13 to 14 mm, and many replicas add a millimeter or more.
- Subdial spacing: running seconds at 9 and the 12-hour counter at 6 should sit close to the center, the signature of the Lemania-based layout.
- Hand length: the chronograph seconds hand should reach the inner tachymeter track.
- Bezel: numeral weight, the position of the dot next to 90, and the finish of the black aluminum insert.
- Caseback: engraving depth, the seahorse, and the FLIGHT-QUALIFIED text.
- Movement: the genuine caliber is hand-wound. A quartz tick or a rotor visible through the back is an immediate tell.
What Movements Appear in 311 Speedmaster Replicas?
Most 311 replicas run a Seagull ST19, a Chinese hand-wound column-wheel chronograph derived from the Venus 175. Some higher-priced builds use a decorated clone of the Omega 1861, while the cheapest examples hide quartz or a 7750-type automatic behind a solid back. None of these match the finish, serviceability, or resale of a real Lemania-based Omega caliber.
Is Buying a Speedmaster 311 Replica Legal in the US?
No. Selling counterfeit watches is illegal, and US Customs and Border Protection can seize and destroy counterfeit shipments. Importing a counterfeit for personal use is also prohibited, and trafficking carries criminal penalties under 18 U.S.C. 2320. Consult a licensed attorney about your own situation.
What Should You Confirm Before Ordering?
- The full nine-digit reference, written out, not just "311."
- Movement type and caliber, confirmed in writing.
- Recent photos of the actual watch rather than catalog renders.
- Case dimensions and crystal material.
- A stated return window and a payment method with buyer protection.
Key Takeaways
- 311 is a reference prefix, so always ask for the complete number.
- Proportion, not branding, is where most replicas fail.
- Counterfeit sales and imports are illegal in the United States.
