Reference 210.92.42.20.01.003 brings the Seamaster Diver 300M No-Date into a material combination Omega has never offered before: a titanium case paired with bronze-gold elements in the brand's own 9K alloy. Collectors call it the "Bronze Gold Burgundy Diver," or "SD300M BronzeGold NoDate" for short, and on the rubber strap it often goes by "Bronze Gold on Rubber" in forums. At its core sits the Caliber 8806, running Co-Axial escapement with Master Chronometer certification, with a case diameter of 42mm, matching the rest of the No-Date lineup.
The black dial with its laser-etched wave pattern carries an aluminum bezel in burgundy, vintage SLN-style, with a 60-minute scale — not the ceramic insert found on the regular Diver 300M models. It's this exact combination of bronze-gold case rings and the dark red insert that sets the reference apart visually from the standard titanium version. And because the 9K bronze-gold alloy actually contains gold, the case won't develop the patina you'd get with classic bronze.
## From 007 Special Edition to a Full Bronze-Gold Line
The No-Date concept started in 2020 with the 007 Edition, 210.90.42.20.01.001, in grade 2 titanium, built for Daniel Craig's final outing as Bond in "No Time To Die" — a special edition outside the regular collection. It wasn't until November 2024 that the No-Date concept was permanently added to the lineup with four regular references, listed at 6,600 euros for the rubber strap and 7,300 euros for the bracelet version. The Bronze Gold variants followed in February 2025: alongside 210.92.42.20.01.003 on rubber, a sister model arrived on a bronze-gold mesh bracelet, 210.90.42.20.01.003, known among collectors as the "Ironman." A few months later, Omega rounded out the line with a green titanium-bronze-gold version, 210.92.42.20.10.001.
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.
