If you are shopping for a fake Globemaster 45mm, the first thing to know is that Omega does not make a 45mm Globemaster. The official Globemaster line uses a 39mm case. A 45mm replica is therefore a fantasy size, not a copy of a real reference. That does not make it a bad watch, but it means you should judge it as a large dress-style watch, not as a faithful replica. Buy only if you want the look and accept the size mismatch. If accuracy matters, look for a 39mm replica instead.

What to look for in a fake Globemaster 45mm

Because the size is off, your inspection should focus on build quality and movement choice. A large case makes flaws easier to see, so the details matter more.

  • Case and bezel: The real Globemaster has a fluted bezel and a pie-pan dial. On a 45mm fake, check that the fluting is cut, not stamped. Stamped fluting looks shallow and rounds off. The bezel should sit flush with the case and not have sharp edges.
  • Movement: A decent fake should use a clone of the Omega 8900 or 8901, a Miyota 9015, or a well-finished ETA 2824 clone. Ask for a movement photo and a timegrapher reading. Avoid unbranded 21-jewel movements with rough finishing.
  • Dial and hands: The pie-pan dial should have crisp printing and applied markers. Check that the hands are the correct shape and that the lume is even. A crooked date window is a common flaw on cheap replicas.
  • Bracelet and clasp: Look for solid end links, screw pins instead of friction pins, and a clasp with clean engraving. A flimsy bracelet makes a large watch feel cheap.
  • Weight and feel: A 45mm dress watch should have some heft. If it feels light and hollow, the case is likely thin brass with poor plating.

Parameter bands that matter

  • Case diameter: 39mm for the real reference. 45mm is a fantasy size. If the listing says 45mm, confirm with a photo against a ruler.
  • Thickness: 12mm to 13.5mm. Over 14mm looks slab-sided on a dress watch.
  • Lug width: 20mm on the 39mm original. A 45mm fake may use 22mm or 24mm. Check strap availability.
  • Movement: A reliable clone of the Omega 8900/8901, or a Miyota 9015, or an ETA 2824 clone.
  • Power reserve: 40 to 60 hours is normal for a decent automatic. Under 30 hours suggests a cheap movement.
  • Water resistance: 50m to 100m. A dress watch does not need more, but the gaskets should be present.

Pitfalls to avoid

  1. Buying a 45mm fake and expecting it to wear like the real 39mm Globemaster. It will feel much larger.
  2. Paying extra for Swiss made on a fantasy case. The label is meaningless if the size is wrong.
  3. Ignoring date alignment. A crooked date window is a sign of poor quality control.
  4. Missing anti-magnetic claims. The real Globemaster is a Master Chronometer. A fake will not match that, so treat any such claim with doubt.
  5. Thin plating on the bezel. Fluted edges wear through fast if the base metal is brass.

FAQ

Is there a real 45mm Omega Globemaster? No. Omega lists the Globemaster at 39mm. A 45mm version is a replica-only size.

What movement should a good fake Globemaster 45mm have? A clone of the 8900/8901, a Miyota 9015, or a well-finished ETA 2824 clone. Ask for a movement photo and a timegrapher reading.

How can I spot a low-quality fake Globemaster 45mm? Look for a stamped bezel, printed dial markers that sit flat, a noisy rotor, and a case that is thicker than 14mm. Also check the crown threads and the clasp engraving.

Should I buy a 39mm replica instead? If you want the closest match to the real Omega Globemaster, yes. The 39mm size is the correct proportion and will wear better under a cuff.
