A side-by-side comparison video between the Omega Seamster Diver 300M with black laser-etched ceramic dial and black ceramic bezel and the Seamaster Diver 300M with white laser-engraved ceramic dial and black ceramic bezel.

The black Seamaster Diver 300m has the reference number 210.30.42.20.01.001 and the white version Seamaster has the reference number 210.30.42.20.04.001.

The two timepieces are identical to each other, both equipped with a ceramic bezel, ceramic dial, helium escape valve, 42mm stainless steel case, and powered by Omega's in-house caliber 8800. The difference is their colorway. The black Seamaster has a black polished ceramic dial and a black ceramic bezel. The white version has a white brushed ceramic dial and black ceramic bezel. For legibility, the hands and indices' metal has been PVD treated.
