The Omega Constellation Manhattan 25 in two-tone is not a compromise between yellow gold and steel — it is the definitive answer for buyers who know exactly what they want. The 25 mm case houses the Calibre 4061, Omega's quartz movement for the smaller Constellation, which keeps time to within ±15 seconds per month — more accurately than most competitors at this case diameter. Reference O13120256002002 covers the entire 2020 production run in this size.
## Five Dials, One Bezel, Clear Price Differences
The reference comes in five dial variants: Crystal White with yellow gold appliqués, White Mother-of-Pearl, and Champagne without stones, plus two diamond-set versions — including the rare Blue Aventurine. The fixed yellow gold bezel with Roman numerals is the unifying element across all 2020 dials. On the market, the price gap between stone-set and stone-free variants runs 15 to 20 percent in favor of the latter.
## Why Two-Tone Works Especially Well at 25 mm
On small ladies' watches, two-tone often falls flat because the precious-metal content ends up reading as decorative trim around the edges. The Manhattan's construction avoids this: the case and integrated bracelet distribute the materials evenly across the piece. Pre-owned examples of the O13120256002002 are currently trading on Chrono24 between $2,743 and $4,343. Complete sets with original documentation hold their value roughly 12 percent more firmly than watches sold without accessories — a consistent pattern across multiple production years for this model.
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.
