What Is a Replica Globemaster Co-Axial Master Chronometer?
A replica Globemaster co-axial Master Chronometer is a copy of the Omega Globemaster, the first watch to earn Master Chronometer certification from METAS. The copy reproduces the 39 mm case, the fluted tungsten-style bezel, and the pie pan dial. It does not reproduce the co-axial escapement inside the real calibre 8900.
That gap matters. Buyers search this term because the genuine Globemaster has two selling points: the co-axial movement and the METAS certification. Replica makers print both names on the dial and the caseback. The mechanical reality is different.
This guide covers what those names mean, which movements show up in copies, and how to judge one before you pay.
What Makes the Real Globemaster a Master Chronometer?
Omega launched the Globemaster in 2015 as a tribute to the 1952 Constellation. It was the first watch certified by METAS, the Swiss Federal Institute of Metrology.
Master Chronometer certification is stricter than a standard chronometer rating. Each movement is tested as a complete cased watch, not as a bare movement on a bench.
The eight METAS tests
- Function on a full wind and after 24 hours
- Average daily rate in six positions, held to 0 to +5 seconds per day
- Rate and amplitude deviation after exposure to 15,000 gauss
- Water resistance and magnetic field checks
The 15,000 gauss test explains the thick case. Omega builds the movement from non-magnetic parts, so no soft iron cage is needed.
What the co-axial escapement does
The co-axial escapement was designed by George Daniels and put into series production by Omega in 1999. It swaps the sliding friction of a standard lever escapement for near-tangential impulses. That cuts wear on the pallet stones and holds a stable rate over longer service intervals.
You can spot it through a caseback. A co-axial movement has a three-level escape wheel stack. A standard Swiss lever movement has a single escape wheel.
What Movement Is Inside a Replica Globemaster?
Replica factories do not fit a co-axial escapement. The part count and tooling cost sit far above the price point. Almost every copy uses a standard lever escapement under a decorated rotor.
Swiss ETA or Sellita based
The better copies run an ETA 2824-2, a Sellita SW200, or a close Asian equivalent. These movements are proven, easy to service, and beat at 28,800 vph. Decorated versions add Geneva stripes, blued screws, and an 8900 engraving on the rotor.
You get Swiss reliability and a movement any watchmaker knows. You do not get a 60-hour power reserve. Expect about 38 hours.
Clone 8900 movements
Several factories sell a so-called clone 8900 with a bridge layout that matches the real calibre. The parts are Asian, the finishing is cosmetic, and the escapement is a plain lever. It looks right on the wrist and through a sapphire caseback.
Power reserve on these copies runs 40 to 48 hours in most samples. Some come in closer to 36.
Which one to choose
- Pick Swiss-based if you want a movement a local watchmaker can service
- Pick the clone 8900 if the caseback view matters more than serviceability
- Skip quartz versions, since they lose the sweeping seconds hand
What Should You Check Before Buying?
- Case size. The real watch is 39 mm wide and about 12.5 mm thick. Copies that run past 13 mm sit high on the wrist.
- Bezel finish. The genuine bezel has a fluted edge in tungsten carbide, a hard grey metal. Replicas use steel or plated alloy, which scratches.
- Dial printing. Look at the Master Chronometer line. Blurry or heavy type is the fastest tell.
- Hands and indices. You want faceted, polished edges with clean lume fill. Flat hands look cheap.
- Crystal. Sapphire on top, with inner anti-reflective coating on the best versions. Mineral glass fogs and scratches.
- Weight. A 39 mm steel watch should feel substantial, about 130 to 150 grams on a bracelet.
- Water resistance. Treat any replica as splash-proof. Gaskets are the first thing factories cut.
Case and bracelet details
The Globemaster uses twisted lyre lugs, a shape that angles away from the case. That shape is hard to copy, so check that the lugs are not straight bars. The bracelet mixes brushed links with polished center links on some references.
Strap options matter too. Most replicas ship on leather with a deployant clasp. A few ship on a steel bracelet with a butterfly clasp.
How Much Does a Replica Globemaster Cost?
Prices split by movement and finish. Entry copies with Asian automatic movements run $80 to $150. Mid-tier models with better cases and dial work run $180 to $300. Swiss movement versions and the best clone 8900 builds run $350 to $600.
Anything under $70 points to a quartz movement, a plated case, or mineral glass. You can read the difference in the weight and the dial print.
Frequently Asked Questions
Does a replica Globemaster have a real co-axial escapement?
No. No replica at any price has a working co-axial escapement. Some carry a bridge shaped to look like one, but the escapement is a standard Swiss lever.
Will a replica Globemaster pass as the real thing?
At arm's length, a good copy looks convincing. Under a loupe or on a timegrapher, it fails. Caseback engraving, movement finishing, and rate stability give it away.
How accurate is a replica Master Chronometer?
A Swiss-based copy can hold -10 to +15 seconds per day after regulation. The genuine Globemaster must hold 0 to +5 seconds per day across six positions and after magnetic exposure. Replicas are not tested that way.
Can a watchmaker service a replica Globemaster?
Yes, if it runs an ETA, Sellita, or common Asian automatic. Parts for the clone 8900 are harder to find, and many shops decline that work.
Caring for a Replica Globemaster
Keep it away from strong magnets, even though the dial says otherwise. Standard lever movements magnetize and start running fast. A demagnetizer fixes that in seconds.
Have the movement cleaned every four to six years. Avoid wearing it in a pool or shower. Wipe the case with a soft cloth, and store it on a watch roll rather than flat on a dresser.
