The O32933435102001 is the variant with an opaline white silver dial and a blue aluminum tachymeter bezel — the exact combination collectors have argued about most fiercely since its 2021 debut. The Bi-Compax layout, with elapsed minutes at 9 o'clock and running hours at 3 o'clock, draws on the Swiss chronograph aesthetic of the 1940s, yet stays thoroughly readable in the contemporary 43-millimeter case.
## Calibre 9908: 15,000 Gauss and a dead-clean start
The Co-Axial Master Chronometer calibre 9908 runs 60 hours on a single wind and holds METAS accuracy of +5/−0 seconds per day. The movement is certified for magnetic fields up to 15,000 Gauss — a threshold that is anything but standard among chronographs in this price bracket. The vertical clutch ensures the chronograph seconds hand engages cleanly and without the telltale jerk the moment you push the button.
## Why one reference goes by four collector names
In the community, the O32933435102001 has picked up four unofficial monikers: Chronoscope, Snail Dial Speedy, Tri-Scale Speedmaster, and Retro Bicompax Speedy. The silver opaline dial carries three concentric scales — tachymeter, pulsometer, and telemeter — whose depth of information reveals itself through use rather than at a glance. Pre-owned examples with box and papers are currently trading between 5,800 and 6,400 euros, with the condition of the blue bezel being the decisive factor on price.
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.
