Omega Seamaster 300 Co-Axial Master Chronometer 42mm Steel on Steel

210.30.42.20.10.001 

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.

This 42 mm model is crafted from stainless steel and includes a green ceramic bezel with a white enamel diving scale. The dial is also polished green ceramic and features laser-engraved waves and a date window at 6 o’clock.

The skeleton hands and raised indexes are rhodium-plated and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.

The watch is presented on an adjustable stainless steel bracelet with extra diver extension, and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.
