A Speedmaster 311 replica costs $180 to $450. Under $150 you get quartz or a chronograph with the wrong subdial layout. The reference 311.30.42.30.01.005 is a 42mm steel Moonwatch with a hesalite crystal, a hand-wound calibre 1861 and 50 meters of water resistance. No copy matches all of that. The checks below sort a close replica from a costume piece.

What Reference 311.30.42.30.01.005 Is
Omega built this reference as the Moonwatch Professional. Key numbers:
speedmaster 311 replica vs real
- Case: 42mm stainless steel, about 14mm thick
- Lug width: 20mm
- Movement: calibre 1861, hand wound, 48 hour power reserve
- Crystal: hesalite, an acrylic, domed
- Water resistance: 50 meters from the factory
- Dial: three subdials at 3, 6 and 9
- Caseback: solid steel with engraving
Replica makers copy the case shape first and the movement last. That order shows up in photos.

Movement: The First Check
Most Speedmaster replicas use a Seagull ST19. It is hand wound, it has a column wheel, and it places the subdials at 3, 6 and 9. That matches the Moonwatch layout.
Two movements do not match:
- A 7750 based automatic puts a subdial at 12. The Moonwatch has none there.
- Quartz: the seconds hand ticks once per second.
Ask for a short video with the caseback off. A hand-wound chronograph has no rotor. If the caseback is solid, ask for a photo of the threads and gasket. Then ask about the last service.
Dial and Subdials
- Subdial spacing. The 3 and 9 subdials sit close to the center on a 42mm dial.
- Text. The dial prints OMEGA, Speedmaster and PROFESSIONAL in a thin font. Heavy or blurry print is a reject.
- Logo. Compare the Omega symbol with reference photos. Flat printed logos and thick raised logos both appear on copies.
- Hands. The chronograph seconds hand should reach the inner edge of the minute track.
- Lume. Painted lume that sits above the dial surface looks wrong in daylight.
Bezel and Crystal
The 311 bezel insert is anodized aluminum, not ceramic. The tachymeter print sits under the surface. Check the dot position next to 90 against photos of the reference year, because Omega changed it across the years.
The factory crystal is hesalite. It flexes under a fingernail and scratches. Many replicas ship with mineral glass or sapphire, which look flatter at the edge. Ask which material is fitted.
Caseback and Case
The 311 caseback carries NASA flight qualification text and an engraved seahorse medallion. On replicas the text depth is shallow and the seahorse loses detail. Look at the crown and pushers. The pushers should be smooth and sit level, and the crown should seat flush.
Bracelet
Check end link fit against the lugs. Gaps at the top of each end link show a mismatched bracelet. Open the clasp. Stamped logos fade and misalign on copies. Spring bars should be about 1.8mm.
Price Bands
- $80 to $150: quartz, mineral glass, printed dial
- $180 to $300: ST19, mineral or hesalite glass, cast case
- $300 to $450: ST19, hesalite or sapphire, better case finishing
- Above $500: ask what the extra money buys. Most listings cannot answer.
Prices move with shipping and customs fees. Confirm the total before payment.
Questions for the Seller
- Which movement, and can you send a running video?
- Which crystal material?
- Does the chronograph reset to zero?
- What is the case diameter and lug width?
- What is the return window?
After the Sale
Do not swim in a replica. Gaskets and case threads vary. Have a watchmaker pressure test it if water contact is expected. A full service on an ST19 costs $80 to $150 in the US, and parts for generic movements are common.
None of these watches carry an Omega warranty, METAS certification or factory parts. Resale is near zero. Buy on the checks, not the story.
