Serial numbers

The Omega Speedmaster Moonphase Chronograph Master Chronometer — known in collector circles simply as the "Speedy Moonphase" or "Black Moonphase Steel" — carries reference O30430445201001 and represents the moment Omega married classic Speedmaster DNA to a genuine astronomical complication. Calibre 9904 beats at 28,800 vph, holds METAS certification, and resists magnetic fields of 15,000 Gauss — a threshold where most Swiss precision movements simply fail.
## What the Dial Tells You About the Watch
The black sunray-brushed base dial with rhodium-applied indices is no design compromise. It frames a moonphase display calibrated to an astronomical deviation of no more than one day in 122 years. That's not a marketing number — that's precision engineering inside a 44-millimetre case. Combined with the black ceramic bezel and Liquidmetal tachymeter, the overall effect is considerably more cohesive than many of the colourful Speedmaster editions Omega has released in recent years.
## Market Position in the Pre-Owned Segment
Retail sits at around $11,659. On the pre-owned market, the O30430445201001 trades between $8,458 and $10,401 depending on condition and completeness — box and papers typically add a premium of $914 to $1,372. Compared to the straight chronograph variant, the moonphase complication carries a roughly $2,858 premium. For those buying it as a daily wearer, the calibre holds its rate without producing any meaningful gain in everyday use.
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.
