A fake Omega Constellation 2018 is a counterfeit of the line Omega relaunched at Baselworld in 2018. Genuine examples carry METAS Master Chronometer certification, an in-house calibre from the 8800 family, and a test card whose serial matches the number engraved on the caseback. Most replicas copy the case outline and fall apart on the movement, the engraving depth, and the paperwork.

What defines the 2018 Omega Constellation?

Omega redesigned the Constellation in 2018 and retired the older Double Eagle look. The new case has two claws at 3 and 9 o'clock that clamp the bezel, a slim profile, and a dial that spells out "Constellation" under the Omega symbol. Earlier generations used a Roman numeral bezel and a different case shape, so a 2018 counterfeit should not share parts with a fake from 2005.

Size and reference numbers

The main 2018 models came in 39 mm and 36 mm, with smaller sizes for the ladies' line. Reference numbers for this generation start with 131, such as 131.10.39.20.01.001 for a 39 mm steel piece on a bracelet. The tail of the reference points to dial color and stone setting, so a seller who cannot produce the full number is a problem.

Movement specs a photo cannot prove

Calibre 8800 (and its gold-rotor sibling, 8801) uses a co-axial escapement, a free-sprung balance with a silicon hairspring, and 55 hours of power reserve. Omega rates these movements for magnetic fields up to 15,000 gauss and for daily accuracy of 0 to +5 seconds. Replica movements are Miyota, Seagull, or ETA clones with none of those parts, and they drift outside that range within weeks.

How do you spot a fake Omega Constellation 2018?

Start with the dial, then work toward the movement. A counterfeit can pass a phone photo and still fail a five minute hand check.

  • Dial text: genuine "Co-Axial Master Chronometer" print sits crisp and flat under a loupe; fakes look printed or fuzzy.
  • Applied indexes: real ones are polished on top and brushed on the sides, with a hard step between finishes.
  • Caseback: deep engraving with bright cut walls and a matte floor, never a gray laser etch.
  • Claws: both claws should line up with the bezel edge and sit at the same height.
  • Bracelet: end links flush at the lugs, no rattle, no gaps at the clasp.
  • Paperwork: a METAS card with a serial that matches the caseback and movement.

Dial and hands

The 2018 dial has a sunburst or flat finish with a sharp color break at the edge. Hands are faceted and diamond-polished, so light runs down the length of each one. Fakes show painted markers that look flat, a logo with soft edges, and a date window cut with a straight blade instead of a beveled frame.

Case and caseback

Omega engraves the back with the reference, the serial, "Constellation", "Master Chronometer", and the 15,000 gauss line. Cutting depth is the giveaway: real engraving feels sharp under a fingernail. Shallow laser marks look gray and wash out at an angle.

Bracelet, clasp, and crown

The bracelet closes with a butterfly clasp that carries a stamped Omega symbol, and the crown shows the same mark. Links should move without slop and the end links should sit flush against the case. Copies show gaps at the lugs, a rough crown stamp, and links that pinch skin.

What paperwork comes with a genuine 2018 Constellation?

Every Master Chronometer watch ships with a certification card that lists the eight METAS tests and the watch serial. That serial must match the caseback and the movement, and Omega keeps a record of it. A boutique or an authorized service center can confirm a watch in minutes, which is the fastest test available to a buyer.

Why do "Swiss ETA" claims about Constellation 2018 replicas make no sense?

No 2018 Constellation left the factory with an ETA movement, so a listing that promises a "Swiss ETA 2824" inside one is describing a watch that never existed. Sellers use that phrase to justify a higher price. Counterfeiters also print fake cards, but the serial on those cards will not appear in Omega's records.

How do you check a used Constellation before you pay?

  1. Ask for the full reference and serial, then verify the serial with Omega or a boutique.
  2. Meet at a watchmaker and have the caseback opened in front of you.
  3. Compare the movement to photos of calibre 8800: rotor finish, bridge layout, jewel count.
  4. Run it on a timegrapher and check rate, beat error, and amplitude.
  5. Confirm the METAS card number matches the case and the movement.
  6. Walk away if the seller refuses any of the first five steps.

FAQ

Can a jeweler tell a fake Constellation 2018 without opening the case?

Often yes. Dial print, engraving depth, claw alignment, and bracelet fit give it away at arm's length for anyone who handles the real line. A confident answer still needs the caseback open, because the movement is the part fakes cannot match.

Are "1:1" or "super clone" Constellations hard to spot?

They look close in photos and fail in the hand. Weight balance, crown feel when winding, and crown thread pitch are hard to copy at scale. The movement inside is still a third party calibre with a decorated rotor plate.

What should a used 2018 Constellation cost?

Steel models trade under original retail, and solid gold or diamond-set pieces hold more value because of the metal. There is no fixed number, since dial color and condition swing the price. A 2018 Constellation offered far below the market for its reference is a warning sign, not a bargain.

Does the claw design make fakes easier to spot?

Yes. The claws are milled as part of the case and polished by hand, so the transition from case to claw is smooth. Copies cast the claws with the case in one piece or glue them on, which leaves a ridge or a gap at the joint.

Bottom line

Buy from a seller who will open the case, hand over the METAS card, and match the serial to the watch. If any one of those three is missing, treat the watch as a fake until proven otherwise. The 2018 line sits inside a known reference range, so any piece that does not match an official reference is a counterfeit.
