Fully lumed scale on a black anodized bezel and milanese mesh leads the configuration
The 210.30.42.20.01.010 is an Omega Seamaster Diver 300M whose identity is established by its fully lumed scale on a black anodized bezel and Milanese mesh. That visible treatment gives the watch a more specific point of view than a generic black, blue, or steel variant. The approved front and angled views should be read together: one establishes the dial and bezel relationship, while the other shows how the case surfaces continue into the wrist connection.
The final record lists a 42.0mm case in Stainless Steel. Those proportions are not background information; they determine how much of the design reaches the wrist. The Matte Black Aluminum dial and Black oxalic anodized aluminum, fully lumed scale bezel create the front-facing contrast, with the Sapphire completing the listed configuration.
