## Blue on Sedna — when PVD treatment is no compromise
The dial is PVD-coated in a warm blue, identified internally at Omega as 434.20.34-03-Blue. Applying PVD coatings to precious-metal components is significantly more involved than industry standard — the hue holds up far more reliably under UV exposure than wet paint. Paired with the Sedna Gold indices, the blue reads warmer than a pure cold blue without tipping into rosé clichés.
## Cal. 8800: 15,000 Gauss, because the world is full of magnets
Beneath the caseback, calibre 8800 does its work — a METAS-certified Master Chronometer rated to within 0 to +5 seconds per day and antimagnetic to 15,000 Gauss. Power reserve stands at 72 hours, with an oscillation frequency of 25,200 vibrations per hour. For a ladies' watch at this price point, it is a level of movement quality that leaves many competitors' men's watches looking underspecified — not a marketing claim, but a measured and certified specification.
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.
