What is a fake Speedmaster 311?
A fake Speedmaster 311 is a counterfeit of the Omega Speedmaster Professional Moonwatch, the 42 mm hand-wound chronograph whose reference numbers start with 311. A real one runs on Omega caliber 1861 or 3861, carries a signed caseback with a serial number, and sells new for $5,000 or more. Fakes copy the shape, the dial, and the box, but they miss the movement, the lume, and the case finishing.
The term covers everything from a $60 quartz lookalike to a $900 clone with a copied movement. Which one you are looking at decides how the watch runs and what it is worth.
What does 311 mean in an Omega reference number?
Omega builds reference numbers from blocks of digits, and the first three tell you the product line and case material. The 311 prefix marks a Speedmaster Professional in a stainless steel case, so any watch sold as a 311 without a steel case and a Speedmaster dial is wrong from the start.
Which Speedmaster references start with 311?
- 311.30.42.30.01.005: 42 mm Moonwatch, hesalite crystal, caliber 1861
- 311.30.42.30.01.006: 42 mm Moonwatch, sapphire crystal and display back, caliber 1863
- Other 311 numbers in the same block: 42 mm Speedmaster Professional variants with different dial and metal combos
The last digits of a 311 reference describe the dial color and the strap or bracelet fitted at the factory. Two watches can share a case and still carry different full numbers.
How do you spot a fake Speedmaster 311?
Check the movement first, then the caseback, then the dial. Those parts cost the most to copy, so fakes cut corners there before anywhere else.
1. Movement and winding feel
A genuine 311 runs a hand-wound column-wheel chronograph: caliber 1861 on hesalite models, 1863 on sapphire ones. Wind the crown and you feel 30 to 40 clicks of a smooth ratchet. A gritty or silent crown points to a quartz module or a cheap automatic hidden behind a solid caseback.
If the watch has a display back, count the jewels, check the bridge finish, and look at the balance wheel. Copy movements show flat plating and stamped, not engraved, lettering.
2. Caseback and serial number
Real Moonwatches carry the Seahorse medallion, the text FLIGHT-QUALIFIED BY NASA FOR ALL MANNED SPACE MISSIONS, and a serial engraved on the case flank. Fakes use shallow laser etching, the wrong font weight, and serials that repeat across listings. Search the serial online. If two sellers show the same digits, both watches are fakes.
3. Dial, hands, and subdial spacing
On a real 311 the three subdials sit at 3, 6, and 9 with even gaps and the Swiss Made print centered under the 6. Fakes drift, so the text lands off center and the subdial hands wobble. Applied logos sit flush on genuine dials and look thick or glued on copies.
4. Lume
Genuine Super-LumiNova glows green and stays readable for hours after a minute under a lamp. Fake lume fades in under ten minutes and looks blotchy under a loupe. This test needs no tools and no seller permission.
5. Crystal, case, and bracelet
Hesalite crystals on real 311 references have a warm, domed look that shows fine scratches over time. Sapphire models use anti-reflective coating on the inside only, so the dial stays clear from an angle without a blue tint. Case edges feel sharp where brushed surfaces meet polished bevels. Fakes round them off.
6. Box, papers, and price
A full set has the outer box, the red travel case, the warranty card, and the pictogram card with a reference and serial that match the watch. A brand-new Moonwatch listed under $1,500 is a fake. Real ones hold value, so nobody dumps them at 80% off.
What do replica Speedmaster 311 watches cost?
Replica pricing splits into three tiers, and each one behaves in a different way.
- Entry ($50 to $150): quartz or basic automatic, painted subdials, mineral glass, wrong thickness and weight.
- Mid ($200 to $400): automatic with working subdials, sapphire glass, closer case shape, caseback details still wrong.
- High end ($500 to $900): super clone builds with copied dials, correct 42 mm dimensions, and movements that mimic the 1861 layout.
Even the top tier differs from a real Moonwatch in movement construction, engraving depth, and lume output. Sellers who promise a Swiss movement inside a $300 watch are describing a Chinese or Japanese caliber with printed decoration.
Is buying a fake Speedmaster 311 legal?
Selling counterfeit watches is illegal in the US under the Trademark Counterfeiting Act, and Customs can seize parcels at the border. Buying for personal use sits in a gray area that varies by country and state. Owners also get no Omega service, no warranty, and no resale market, which is where most of the value of a real Speedmaster lives.
FAQ
How much does a fake Speedmaster 311 cost?
Most fakes sell between $50 and $900. Anything above that range is either a real vintage Speedmaster or an overpriced copy.
Can a jeweler spot a fake Speedmaster 311?
Yes, and it takes minutes. A watchmaker opens the caseback and checks the caliber number, the jewel count, and the engraving. Most fakes fail at that step.
Does a fake Speedmaster 311 keep time?
Quartz fakes keep time to a few seconds a month, though the chronograph often stops working. Cheap automatics drift 20 to 40 seconds a day. High-end clones can run within 10 seconds a day after regulation, but service is hard to find.
Why do people search for a fake Speedmaster 311?
Most search because they found a cheap Moonwatch on a marketplace and want to check it before paying. The 311 line is the most copied Speedmaster because it is the most recognized.
Can you service a fake Speedmaster 311?
Some shops will, many will not. Parts are not interchangeable with Omega calibers, so a broken fake often becomes scrap. Budget for a replacement, not a repair.
What should you check before you pay?
The 311 prefix points to the Omega Speedmaster Professional Moonwatch, and that is the exact model counterfeiters target. Movement, caseback, lume, and papers separate a real one from a copy in a few minutes. If the price looks too low for a steel Moonwatch, the watch is not genuine.
