The Omega Speedmaster FOiS, reference 310.30.40.50.06.001, replaced its predecessor, reference 311.32.40.30.01.001 from 2012, in October 2024. Twelve years and a complete caliber change separate the two watches: the old Cal. 1861 gave way to the Cal. 3861, with co-axial escapement and a silicon balance spring. Power reserve grew from 48 to 50 hours, and METAS certifies the deviation at 0 to +5 seconds a day. Collectors know the reference by several names — FOiS, First OMEGA in Space, sometimes also CK2998 Revival or Sigma 7 Tribute, depending on the forum and the production-year context.
## Slate Blue-Grey Instead of Black on the Dial
The most noticeable difference sits up front. Instead of the black dial from 2012, the 2024 version wears a CVD-coated dial in slate blue-grey, tracked internally under the code FOIS-2024-06-GreyBlue-CVD-AlphaAppl. It's paired with a sapphire crystal shaped to mimic Hesalit — a nod to the sixties look, without inheriting the original material's tendency to scratch.
## The DON Bezel and Three Ways to Wear It
Among collectors, the bezel goes by the name DON Bezel — fixed in place, black aluminum insert, no rotating tachymeter scale like some Speedmaster variants have. New is the Flatlink bracelet as a third wearing option alongside leather and rubber, which puts the brown leather strap of the 2012 version to rest. For market valuation, what matters most is the reference number 310.30.40.50.06.001 itself, not the nickname used in forums.
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.
