The Omega Constellation Manhattan 28 YG, reference O13125286052002, also shows up in the trade under the name Constellation Ladies Diamond YG 28mm. Both names refer to the same watch: a 28mm yellow gold case with a bezel set with 36 diamonds. Search for the Manhattan line under either name at Omega and you'll land on the same result - worth knowing when researching the secondary and auction market.
## Caliber 4061 under the hood
The watch is powered by caliber 4061, a quartz movement. No chronometer certification, no power reserve display - this reference of the Constellation Manhattan 28 is built consistently around precision without mechanical complexity. For anyone planning to wear the watch daily, that's a plus: no winding, no regulating.
## Two dials, one case
The reference comes with two dial variants, neither with a date window. One pairs mother-of-pearl white with diamond indices, the other comes in silver with diamond-set indices. Both variants share the same case, bezel, and movement. The only difference lies in the dial - and that's exactly the first thing to check when matching photos against papers.
## What I check when verifying
On a reference with 36 diamonds set into the bezel, I look first at the setting: do the stones sit cleanly, without gaps or visible traces of adhesive? Second is the dial signature against the reference number - Constellation models with diamond settings tend to show more discrepancies in practice than the plainer variants. Check both before the 28mm Manhattan changes hands, and you'll save yourself an argument at resale later.
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.
