The story
The reference 210.30.42.20.01.001 is the black dial, steel bracelet version of the Seamaster Diver 300M that Omega introduced in 2018 to mark the model's 25th anniversary. The original Seamaster Diver 300M launched in 1993 as the 2531.80 (automatic) and 2541.80 (quartz), a design that gained wide recognition after Pierce Brosnan wore it in the James Bond film GoldenEye in 1995 and that stayed on Bond's wrist through several subsequent films. For the 2018 update, Omega grew the case from 41mm to 42mm, moved to a fully ceramic dial and bezel insert with a laser-engraved wave motif carried over from the outgoing generation, and replaced the ETA 2892-A2-based Co-Axial movement with the in-house Master Chronometer caliber 8800. The new movement carries METAS Master Chronometer certification, meaning it is tested for accuracy and resistance to magnetic fields up to 15,000 gauss in addition to standard COSC chronometer testing. Within the current Diver 300M line, 210.30.42.20.01.001 is the baseline steel and black configuration, sitting alongside blue and other dial color variants that share the same case and movement.
What to check before you buy
Confirm the exact reference on the caseback and papers, since the 210.30 case and bracelet combination has been produced with several dial and bezel color options that share a nearly identical silhouette. Because the ceramic dial and bezel insert are more prone to chipping on impact than the aluminum inserts used on earlier Seamaster generations, inspect the bezel edge and dial flange closely under a loupe before buying a used example. Full sets with box, warranty card, and the smaller bracelet links are common since this reference is still in current production. Omega recommends service intervals of roughly 8 years for Master Chronometer calibers, so ask when the movement was last serviced, particularly on watches more than five years old.

Common questions
What movement powers the current Seamaster Diver 300M 210.30.42.20.01.001?
It uses the Omega Co-Axial Master Chronometer caliber 8800, an automatic movement with a 55 hour power reserve that is METAS-certified as a Master Chronometer.
Is this the same watch worn in the James Bond films?
It shares the Seamaster Diver 300M name and general design lineage, but the Bond-associated watches from GoldenEye onward were the earlier 2531.80 and 2541.80 references. The current 210.30 generation dates to the 2018 redesign.
How does this reference differ from the older 41mm Diver 300M?
The 2018 update grew the case to 42mm, switched to a fully ceramic dial and bezel insert, and replaced the ETA-based Co-Axial movement with the in-house caliber 8800.
What water resistance does it offer?
It is rated to 300 meters, in line with the model's dive watch classification, with a screw-down crown and caseback.
Does it have a helium escape valve?
No, the current Seamaster Diver 300M does not include a helium escape valve. That feature is reserved for the deeper-rated Planet Ocean 600M line.
