The Omega Constellation Manhattan 25 with green meteorite dial is one of those watches where the material defines the reference. Every example of Ref. O13115256099001 carries a dial cut from genuine meteorite — the Widmanstätten pattern, formed over millions of years of cooling, can neither be faked nor reproduced. No two examples share the same texture.
## White Gold and Diamonds: What the 25mm Wears
The 25-millimetre bezel diameter belies the extent of the craft involved. Omega opts for a fully diamond-paved bezel in white gold (Diamond-Paved-131.15-WG), with not a single stone spared. Calibre 4061 drives the movement — a quartz calibre that delivers maximum accuracy within minimal space for this case size.
## Why Collectors Place This Piece in a Category of Its Own
In the dealer community, the piece circulates under two names: "Constellation Manhattan Meteorite Green 25" and the shorter "Green Meteorite Claw 25" — the latter a nod to the characteristic Constellation claws that frame the dial. On the pre-owned market, Omega meteorite dials consistently trade at a 15 to 25 percent premium over comparable mother-of-pearl or lacquer variants. The condition of the stone is decisive: cracks or chips in the meteorite are irreparable.
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.
