Search for the Blue Side of the Moon Aventurine and you'll run into at least four names for the same watch – BSotM Aventurine, Blue Side of the Moon Aventurine, BSotM Moonphase .002, and BSotM Aventurine Moonphase. Every one of them points to reference 304.93.44.52.03.002, a Speedmaster Moonphase model with a 44 mm case diameter.
## A Dial Set with Real Stone
Under the sapphire crystal sits an aventurine dial in deep blue with applied Sedna gold indexes – a combination Omega refers to internally as the BSotM Aventurine Moonphase Dial. Aventurine is glass with copper particles melted in, not a mineral in the classic sense, which is what produces the sparkle when light hits it – and it's also a telltale for fakes: replicas usually lack that depth in the material's shimmer.
## Ceramic Bezel with a Ceragold Scale
The bezel is blue ceramic with a tachymeter scale in Ceragold, 44 mm across. Omega has used this process for over a decade to fill ceramic rings directly with 18-karat gold, rather than pressing in a separate metal inlay. On genuine pieces, the gold fill sits flush with the ceramic surface, with no overhang at the edges.
## Caliber 9904 at the Core
Inside beats the in-house Caliber 9904, a Co-Axial Master Chronometer chronograph movement with an astronomical moon phase display that only drifts by one day after 2,045 years. No production changes have been documented for this reference so far – a stable data point that we at ChronoCheck keep cross-checking against new listings on the market.
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.
