Short answer: 123.10 is not a watch, it is the front half of an Omega reference number. On a real Constellation it maps to a stainless steel case around 35mm with an integrated bracelet. A seller who lists "replica omega constellation 123.10 replica" and stops there is hiding the part of the reference that tells you the dial, the movement and the production run. Ask for the full eight-digit string, like 123.10.35.20.02.001, or walk.
What the 123.10 prefix actually means
Omega builds references in blocks. The first five characters describe the case and bracelet family, the middle digits cover the movement and size, and the last group pins down the dial variant. 123.10 points at a Constellation in steel, roughly 35mm across, with the polished claws at 3 and 9 o'clock that have defined the line since the 1980s redesign. So when you see that prefix alone, you know the family but nothing about the specific watch on the bench.

Why a truncated reference matters when buying
Two replicas of the same case can hold completely different movements, and the dial variant changes the value of the original by hundreds of dollars. If a listing cannot produce the full number, the factory either cloned a photo rather than a watch, or it mixed parts from several references. Both outcomes mean the bracelet end links will not sit flush and the date window will land in the wrong spot.

Case and dial points I check first
- Claw profile: the two side claws should be separate polished pieces with a visible seam, not stamped into the case.
- Dial texture: silver, mother-of-pearl and grey variants all photograph the same way under shop lighting, so ask for daylight shots.
- Date aperture: on the 35mm case it sits at 3 o'clock and the frame should be thin, beveled metal.
- Star logo: five points, applied, with sharp inner angles. Blurry stars are the single easiest tell.
The bracelet is where most replicas slip
Integrated bracelets are hard to fake. Look at the gap where the link meets the lugs. On genuine Constellations that gap is consistent along the whole curve. On most replicas it opens up near the clasp because the taper was copied from a photo rather than measured. Also check that the clasp engraving is laser-cut rather than stamped, and that the pins are solid, not folded sheet metal.

What to expect from the movement
Nobody is putting a real Omega caliber in a replica. At this price band you will usually find a Chinese clone of an ETA or a Miyota derivative. That is fine for daily wear, but ask which one and expect a smooth sweep, hacking, and a quickset date. A 28,800 bph clone is the floor. Anything under that feels cheap the moment you set the time.
How I would vet the seller
- Request timestamped photos of the exact unit, not factory stock images.
- Ask for the full reference number and compare it to the dial shown.
- Confirm the return window in writing before payment.
- Check whether the seller shows the caseback and clasp, since those are the first things hidden.
Red flags worth walking away from
Prices far below the market for that factory, no caseback photos, pressure to pay outside a trackable method, and any listing that repeats the keyword "replica omega constellation 123.10 replica" three times without naming a factory. The Constellation is a small, detailed watch, and the good factories name themselves because their work holds up to a loupe.
