Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design. The case of this 43.5 mm model is crafted from black ceramic and grade 5 titanium and includes a black ceramic bezel with a white enamel diving scale. The dial is also brushed black ceramic [ZrO2] and features laser-engraving to create raised waves. The skeleton hands and raised indexes in PVD titanium are filled with white Super-LumiNova, while the helium escape valve has been given a conical design. The watch is presented on an integrated black rubber strap with a polished-brushed black ceramic [ZrO2] buckle, and is driven by the OMEGA Master Chronometer Calibre 8806, which can be seen through the sapphire-crystal on the wave-edged caseback.
