A fake Speedmaster Professional fails on three points: the movement, the subdial layout, and the caseback engraving. A real Moonwatch runs a mechanical caliber, has a small seconds hand at 9 o'clock, and carries a serial number that matches Omega records. Check those three first.
Reference numbers to compare
The steel Moonwatch has a 42 mm case and 20 mm lugs. Common references:
How to Answer the Fake Speedmaster Professional Question
- 3570.50.00: hesalite crystal, steel caseback, Caliber 1861. Built 1996 to 2021.
- 3573.50.00: sapphire crystal and sapphire caseback, Caliber 1861.
- 310.30.42.50.01.001: current hesalite model, Caliber 3861.
- 310.30.42.50.01.002: current sapphire model, Caliber 3861.
A listing where the reference number does not match the case in the photos is a red flag.
Movement checks
The Caliber 1861 runs at 21,600 vibrations per hour with a 48-hour power reserve. The Caliber 3861, in use since 2021, holds Master Chronometer certification from METAS. A watchmaker with a timegrapher reads the beat rate in seconds.

Counterfeit cases hold Seagull ST19 chronographs, low-grade 7750 clones, or quartz modules. A quartz movement inside a Speedmaster is a copy, with no exceptions.
Subdial layout
A Speedmaster Professional has three subdials: small seconds at 9, a 30-minute counter at 3, and a 12-hour counter at 6. The chronograph center seconds start and stop with the pusher at 2.
Copies put running seconds at 6 or add a date window. The Moonwatch has no date. A date aperture at 3 or 4 o'clock means the watch is not a Speedmaster Professional.
Dial, crystal, and bezel
The hesalite Speedmaster has an Omega symbol laser etched at the center of the crystal. The mark is small and sits under the hands. Copies skip it or print a logo on the surface.
Modern references use a 'dot next to 90' bezel. References from before 1970 use a 'dot over 90' bezel. A new case paired with an old-style bezel needs a closer look.
Caseback and serial number
The steel caseback is engraved with 'FLIGHT-QUALIFIED BY NASA FOR ALL MANNED SPACE MISSIONS' and 'THE FIRST WATCH WORN ON THE MOON'. Letters have sharp edges. Omega engraves a serial number on the movement. That number must match any Omega service record.
Price and paperwork
A new steel Moonwatch lists above $7,000 at an authorized dealer. Used Caliber 1861 examples trade for several thousand dollars. A listing at $300 does not carry a real Omega movement.
Verification steps
- Request photos of the dial, caseback, movement, and serial number.
- Compare the reference number against Omega's published specifications.
- Have a watchmaker read the movement serial and the beat rate.
- Send the serial number to an Omega service center for a record check.
- Buy from an authorized dealer or a seller with Omega service history.
Legal status
Counterfeit watches infringe trademarks. US law bans their sale, and Customs and Border Protection seizes shipments at the border. A buyer gets no recourse when a fake stops running and no warranty from Omega.
