A replica Omega Constellation Co-Axial Master Chronometer women's watch is a copy of the 28mm, 29mm, or 36mm Constellation, and it almost always runs a Miyota 9015 or a decorated Chinese automatic instead of Omega's METAS-certified Calibre 8700 or 8800. The engraving on the rotor proves nothing. Judge the piece on case finishing, dial texture, bracelet articulation, and movement reliability, not on the Master Chronometer name.

What Is the Omega Constellation Co-Axial Master Chronometer?
Omega relaunched the Constellation in 2015 with the Master Chronometer badge, which is granted by METAS rather than by Omega itself. A genuine Master Chronometer passed eight tests over 10 days, resists magnetic fields up to 15,000 gauss, and runs within 0 to +5 seconds per day. Women's versions arrive in 28mm, 29mm, and 36mm cases in steel, Sedna gold, or two-tone, frequently with a diamond-set bezel.

The signature design detail is the pair of claws, called griffes, that grip the bezel at 3 and 9 o'clock. The bracelet is a mono-rang design with half-moon facets, and most automatic versions place the date window at 6 o'clock.
Which Sizes and References Do Replica Makers Copy Most?
The 29mm automatic and the 36mm automatic are copied most often because they share case architecture with the men's 39mm line. The 28mm quartz model appears less frequently since the small case is harder to finish cleanly.

- 28mm: quartz movement, slim case, flat dial printing is the usual weak point.
- 29mm: Calibre 8700 layout, diamond bezel options, the most popular women's size.
- 36mm: Calibre 8800 layout, easiest to copy well because parts are shared with larger models.
How Do You Tell a Replica From a Genuine Constellation?
Start with paperwork: every genuine Master Chronometer ships with a METAS certificate card that can be verified, and replicas either omit the card or print a fake one. Next inspect the claws, which should be solid polished metal with crisp edges, and the dial, where sun-brushed or meteorite finishes have depth that printing cannot reproduce.
The movement is the decisive test. Reaching 15,000 gauss of magnetic resistance requires a silicon hairspring and non-ferrous components, and no replica movement delivers that. A watchmaker with a timing machine will also see the difference in rate stability within minutes.
What Movement Sits Inside a Replica Constellation?
Most automatic replicas use a Miyota 9015, a Seagull ST series caliber, or a Chinese movement built to mimic the Omega 8500 architecture with a decorated rotor. Power reserve on those movements runs about 40 hours and the finishing is cosmetic. High-end "super clone" builds pair a gen-spec case with an engraved rotor and a Co-Axial style balance bridge, yet still carry no METAS certification.
What Should You Check Before Buying?
- Case diameter and thickness in seller QC photos, measured rather than described.
- Dial color and bezel material, since replica diamond dots are usually cubic zirconia.
- Bracelet end-link fit, clasp engraving, and whether links use screws or push pins.
- Sapphire crystal with anti-reflective coating on both faces.
- Movement photos plus a video of the watch running on a timing app.
- Return policy and a written warranty on the movement.
What Do Replica Constellations Cost?
Entry quartz versions sell for roughly $80 to $150 and feel like costume jewelry on the wrist. Mid-tier automatics with a Miyota or Seagull movement run about $250 to $450. High-end super clone automatics with a decorated movement and gen-spec case often pass $500.
Are Replica Constellations Water Resistant or Magnetic Resistant?
Water resistance is rarely pressure tested, so treat any rating as decorative and keep the watch away from pools and showers. Magnetic resistance is the one feature replicas cannot reproduce, because the METAS standard depends on movement architecture that copy makers do not build.
