Answer
Omega does not make a 44mm Globemaster. The Omega catalog lists the Globemaster at 39mm and the Globemaster Annual Calendar at 41mm. A listing for a 44mm Globemaster replica describes a case size with no counterpart in the Omega range. Sellers reach 44mm by using a larger case with a Globemaster-style dial, or by measuring the case with the crown included. Ask for the diameter measured across the case at 9 to 3 o'clock, crown excluded, before you compare it to the genuine spec.

Globemaster sizes in the Omega catalog
The Globemaster launched in 2015 as the first Master Chronometer watch. Steel and gold versions measure 39mm across the case. The Annual Calendar version measures 41mm. Both carry a pie-pan dial, a fluted tungsten carbide bezel and a date aperture. Water resistance is rated at 10 bar, or 100m. Steel models use calibre 8900 with a Co-Axial escapement, a silicon balance spring and twin barrels. Gold models use calibre 8901. Power reserve is 60 hours.
What the 44mm label covers
Replica listings that read 44mm sit in a 42mm to 45mm group. Most use a 316L stainless steel case, a sapphire or mineral crystal, and a display back. Claimed water resistance runs from 30m to 100m. The genuine watch is rated to 100m and tested under ISO 22810. A 44mm case weighs more than the 39mm original, so total weight on a bracelet will run high against the real watch.

Movement and finish
Replica movements are Chinese-made automatics with a rotor engraved to look like an 8900. The bridge layout does not match the Co-Axial geometry. Check three points: the beat rate at 25,200 or 28,800 vph, the rotor engraving depth, and the date change at midnight. Genuine calibres are certified by METAS across 8 tests, including exposure to 15,000 gauss and a daily rate of 0 to +5 seconds. No replica carries that certification, and no replica serial number appears in the Omega database.
Checks before you buy
- Case diameter across 9 to 3 o'clock, crown excluded.
- Case thickness against the 39mm original.
- Crystal material: sapphire with anti-reflective coating on both faces.
- Bezel material: tungsten carbide on the original, steel or coated brass on replicas.
- Dial print: pie-pan facets, applied indexes, date font.
- Bracelet end link fit and clasp engraving.
- Movement photo with the caseback removed.
Ask the seller for these photos in writing. If a listing calls the watch 44mm and shows the crown in the measurement, the case is smaller than stated.
