## Why Calibre 3330 Makes the Difference
Inside the case runs Calibre 3330, Omega's Co-Axial chronograph movement with Master Chronometer certification. Accuracy sits at 0 to +5 seconds per day — tested to METAS standard, not COSC. Service interval: 10 years. Anyone who buys and sells regularly knows exactly what that means for resale value.
## Five Dials, One Line — and What That Means for the Market
The O32430385001001 is not the only reference in the Speedmaster 38 family. Omega runs the line with at least 5 dial options, ranging from black through silver/Sedna to the blue-and-white Orbis dial collectors simply call the "Teddy Bear." Three bezel variants — blue, black, and grey — round out the matrix. In 2024 Omega pushed out new colour configurations that Time and Tide covered as they launched. That breadth widens the segment but spreads demand thin across individual references — the blue sunray-brushed version has held steadier on the pre-owned market than the grey variants.
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.
