Short answer
The Omega Constellation 123.10 is a stainless steel Constellation with an integrated bracelet. Omega made this generation from about 2013 to 2020. Cases of 35 mm and 38 mm are the common sizes. Inside sits the caliber 2500 Co-Axial automatic. Replicas of the 123.10 sell for $80 to $400. Replica makers use third-party automatic or quartz movements, not the caliber 2500.

What the reference number tells you
Omega codes references in groups. The first three digits mark the family, so 123 is the Constellation. The next two mark case material, and 10 is stainless steel. The two digits after that give the case diameter. The last groups cover dial color and version. A 123.10.35.20.03.001 is a steel Constellation, 35 mm case, blue dial.

Where replicas differ
Build quality moves by factory and by batch. The same reference number can ship with different parts from one seller to the next. Points to compare:
Constellation 123.10 Omega Replica Watch Guide
- Case thickness. Replica cases measure thicker than the original, and the difference shows at the caseback edge.
- Bracelet end links. Gaps at the lugs, and a claw shape that sits short of the case.
- Dial print. The star logo and the word Constellation sit off center on low grade units. Date font and date window bevel differ.
- Caseback medallion. The observatory dome and eight stars are laser etched or stamped, not raised in relief.
- Movement. Listings claim a Swiss ETA. Shipments hold a Chinese automatic such as a DG2813 or a 2824 clone, or a quartz module in the cheapest tier.
- Crown. Position and size sit close, but stem length changes the winding feel.
Price tiers
- $80 to $150. Quartz or a low grade automatic. Thick case, plain dial print, hollow bracelet links.
- $180 to $300. Automatic with a decorated rotor. Correct case diameter and a closer dial.
- $350 to $500. High grade batch. Better bracelet articulation, correct date font, sapphire crystal.
Checks before you pay
- Ask for the case diameter and thickness in millimeters.
- Ask which movement sits inside and request a photo of the caseback.
- Request a photo of the date window at 3 o'clock to check the font.
- Confirm the return window and the payment method.
