Serial numbers
- ? – ? (2018–?) — Omega has used alphanumeric serial numbers on the case back (laser-engraved) since approximately 2010, no longer between the lugs. Production serial lists for this reference are not publicly documented.
The Omega Constellation Manhattan 25, reference O13110256055001, marks a clean break in Constellation history. Up until 2018, the previous generation ran under 123.10.25.60.xx.xxx with the "Griffes" bezel and its eight star-shaped claws — a design element that had been part of the line's DNA for decades. With the new 131.xx numbering, Omega swept the Griffes motif off the table entirely, replacing it with an engraved steel bezel featuring Roman numerals. Anyone who knows the old watch won't recognize the new one from three meters away.
## Four Claws Instead of Eight, One Bracelet Instead of Two Ends
The 25-millimeter version picks up the full Manhattan vocabulary: a 4-claw bezel setting at the lug attachments and an integrated mono-rank bracelet with no visible transition to the case. The model runs on caliber 4061, Omega's answer to its own chronometer standards within the ladies' line. Collectors refer to the reference under three different names — Constellation Manhattan 25, New Constellation 25, or simply Manhattan Ladies 25 — depending on which forum you're in.
## Five Dials, One Reference
The dial options show off the full range of the 25 line. There's a white mother-of-pearl dial with 12 diamond indices, a silver dial with no stone-setting at all, and a second white mother-of-pearl dial without diamonds. Add to that a silver variant with Sedna gold hands for warmer contrast. The most striking is the blue aventurine dial with diamond-setting, a pattern that sparkles like a night sky depending on the light. Five faces, one case, one reference on the market since 2018.
Brand profile: Omega
Omega is the second most counterfeited Swiss watch brand. The Speedmaster and Seamaster are especially targeted. Pay close attention to movement details (Co-Axial) and dial textures.
- Speedmaster: The chronograph reset hand must snap back precisely to 12 o'clock — fakes stop 1–3 seconds off or wobble
- Speedmaster (Hesalite): The Omega logo is micro-laser-etched on the UNDERSIDE of the Hesalite crystal — only visible at a specific angle and in the right light — fakes omit it or place it incorrectly
- Seamaster: The wave-pattern dial must be ENGRAVED (tactile relief) — printed/flat wave lines = fake
- DON (Dot Over Ninety): small dot ABOVE the '90' on the Speedmaster tachymeter bezel — position/size often wrong on fakes
Serial number format: Omega serial number: 8-digit number on the caseback or between the lugs (on older models). Since ~2018 engraved on the caseback at 6 o'clock. Format: purely numeric. Verifiable on the Omega website with an extract from the archive.
