The Omega Constellation in a 25 mm case isn't a piece of jewelry in the conventional sense — even if the word comes to mind. Reference O13125256060002 wears a diamond-set bezel in pavé Sedna Gold — Omega's proprietary 18-karat alloy that has shown virtually no aging on the secondary market since its introduction in 2012. The calibre 4061 runs as a quartz movement inside: precise, low-maintenance, and exactly the right call for a piece in this category.
## Why "Purple Supernova" Is More Than a Collector's Nickname
The purple dial on this variant carries the collector nickname "Purple Supernova," and the name captures something real. The hue is a deeply saturated violet that reads differently under direct light than it does in product photography. Dealers report that two-tone versions of this Constellation line trade at up to 15 percent above comparable single-material references, because the interplay of steel and Sedna Gold draws in a noticeably wider pool of buyers.
## What the Diamond Griffes Mean for Resale Value
The diamond setting on the bezel follows the Griffes principle — a distinctive claw-set mounting that has been part of Constellation's DNA since the 1980s. Pavé Sedna bezels on well-maintained examples currently come to market between $4,801 and $6,629 depending on the completeness of box and papers. The Pine Green Supernova dial, the second documented variant of this reference, is currently attracting softer demand — putting the price gap between the two variants at around $457.
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.
