The Omega Seamaster Diver 300M Co-Axial Master Chronometer Chronograph 44mm, reference 210.32.44.51.01.001, is known among collectors as the SD300M Chrono 44, with some simply calling it the Black Ceramic Chrono. The dial carries the signature wave pattern in black ceramic with rhodium-plated indices, and the bezel is likewise made entirely of ceramic, with a white 60-minute scale. Inside beats Caliber 9900, Omega's in-house Co-Axial chronograph movement with Master Chronometer certification.
## Two Siblings, One Caliber
In 2021, Omega introduced an America's Cup special edition under reference 210.30.44.51.03.002, built on a steel bracelet instead of rubber, with a blue ceramic dial and a red aluminum regatta ring. The caliber stayed the same, only the case reference shifted from 210.32 to 210.30. Anyone hunting for the 210.32 as the base reference should be aware of this potential mix-up, since both models share the same movement and functional layout.
## 007 First Light: the Newest Variant, from May 2026
May 2026 brought a 007 special edition tied to the First Light video game franchise, reference 210.32.44.51.01.002, with a list price of around 9,300 euros. The chronograph seconds hand and the sub-dial rings appear in PVD bronze-gold, while the rest of the black ceramic configuration stays identical to the standard reference 210.32.44.51.01.001. For authentication purposes, that means hand and ring color are the only reliable way to tell the two references apart — everything else is identical on closer inspection.
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.
