Ref. 329.30.43.51.02.001 belongs to the Speedmaster Chronoscope family, which Omega introduced in September 2021 across seven references. Collectors also know the piece as the "Snail Dial," or simply "Two Counters" — a nod to the distinctive snail-track scale on the two sub-dials at 3 and 9 o'clock. The 43mm steel case houses a silver opaline dial, which is why collectors refer to this reference as the "Silver Chronoscope."
## What's Ticking Underneath
The watch is powered by Caliber 9908, a hand-wound chronograph movement with Master Chronometer certification. Omega fitted this same caliber across all five steel references in the 329.30/32/33 series back in 2021. The only differences come down to dial color and bezel, not the movement itself. This 02 variant's black aluminum tachymeter bezel contrasts with the blue version from the same family, known internally as the "Snail Scale Speedy."
## The Bronze-Gold Mix-Up
Search for the Chronoscope online and you'll quickly run into the 329.92 in Bronze Gold, with its oxidized brown dial — a piece that didn't reach dealers until November 2021, two months after the steel family launched. Both lines share Caliber 9908, but nothing else — not the case material, not the color code. One thing worth clearing up: the Paris 2024 special edition with its white ceramic dial carries the new 522 reference prefix. It has no technical link to the 329 base reference, which has remained unchanged since its 2021 debut.
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.
