In 2020, Omega didn't release the Seamaster Diver 300M NTTD as a single model — it launched as a duo. The Ref. 210.90.42.20.01.001 came on a titanium mesh bracelet for 9,200 US dollars, while its sister reference, 210.92.42.20.01.001, wore a brown-grey-beige NATO strap with a titanium loop and "007" engraving for 8,100 US dollars. Movement, dial, case and bezel are identical across both watches — the 1,100-dollar price gap comes down to the strap alone. If you want to switch reference numbers, you have to swap the entire watch; Omega never designed these references to be converted into one another after the fact.
## A Dial With a Name of Its Own
The tropical brown dial carries the internal designation SD300M-42-Ti-TropicalBrown-BroadArrow-NTTD, and the matching bezel runs the same color code with its 60-minute scale. Power comes from Caliber 8806, the Co-Axial Master Chronometer movement Omega has been fitting across the 300M family for years. On the secondary market, no single name has stuck for this model — buyers search for it as NTTD, Ti007, the Bond Watch, or simply the No Time To Die Seamaster.
## Why Craig's Last Bond Watch Splits Collectors Into Two Camps
Among collectors, the titanium mesh version is seen as the sturdier, more everyday-friendly pick, while its NATO sibling — 1,100 dollars cheaper — nails the original on-screen look. Both references now share the same nickname in 2026: the Daniel Craig Final Bond Watch, the last Seamaster of his era.
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.
