A fake Globemaster 40mm is a counterfeit copy of the Omega Constellation Globemaster, a watch that Omega builds in a 39.5 mm case. Sellers who advertise a "40mm Globemaster" are describing a replica label, not a real Omega reference, because no genuine Globemaster ships at exactly 40 mm. The watch behind that listing almost never matches the original in case material, movement, or finishing.
What defines the genuine Omega Globemaster?
Omega launched the Globemaster in 2015 as its first Master Chronometer watch. The case measures 39.5 mm across, the dial uses a pie-pan shape, and the date sits at 6 o'clock. Steel versions carry a fluted tungsten carbide bezel, and the caseback bears an observatory medallion.
Why is it listed as 40mm?
Replica listings round the case size up to 40 mm because the number reads as a modern men's size and matches other popular references. Factory sellers also reuse a single description across several models, so dimensions drift. Treat any "40mm Globemaster" listing as a sign the seller is not working from Omega specifications.
How can you tell a fake Globemaster 40mm from the real thing?
- Bezel material: Genuine steel models use a fluted tungsten carbide bezel with a hard, glassy sheen. Replicas use polished steel or plated zinc that scratches and dulls.
- Case thickness and profile: The real 39.5 mm case is slim and tapered. Copies commonly run thicker and heavier at 40 mm and above.
- Dial texture: The pie-pan dial has sharp, even steps and crisp applied indexes. Fakes show soft edges, uneven lume plots, and misaligned printing.
- Caseback medallion: The observatory relief is finely struck on the original. Replicas show a shallow, blurry stamp or a sticker.
- Certification: Genuine pieces ship with a Master Chronometer card and a unique serial on the movement that Omega can verify. Counterfeits arrive with generic cards and no verifiable serial.
- Magnet resistance: The real watch tolerates 15,000 gauss. Replica movements have no such protection and can run fast after contact with magnets.
What movement sits inside the original?
The Globemaster runs Omega's Co-Axial Master Chronometer calibers 8900 or 8901, both with a silicon balance spring and a 60-hour reserve. Counterfeits use generic or cloned automatic movements with no METAS testing. That gap drives the difference in accuracy and service life.
Is buying a fake Globemaster 40mm legal in the United States?
No. Trafficking in counterfeit goods violates the Lanham Act and 18 U.S.C. § 2320, and US Customs and Border Protection can seize shipments and destroy them. A personal-use defense does not guarantee delivery, and buyers usually lose the money with no refund path. Rights holders can also pursue civil damages against sellers and resellers.
Does a fake Globemaster 40mm hold value?
Counterfeit watches have no legitimate resale market and no manufacturer service. Omega will not authenticate, repair, or supply parts for a fake, so the watch becomes unusable once it stops. A genuine pre-owned Globemaster keeps a documented value and remains serviceable for decades.
What should a buyer check first?
Start with the case size and bezel material, then verify the serial and Master Chronometer card with Omega. If the listing says 40 mm or avoids the 39.5 mm figure, the item is almost certainly a counterfeit. The safest path is a documented pre-owned genuine reference from an authorized or trusted dealer.
