Since 1993, the Seamaster Professional Diver 300M has achieved iconic status. Now, OMEGA has taken that legendary ocean heritage and enhanced it with their most cutting-edge technology and design.

This 42mm model combines stainless steel and Sedna™ gold to create a luxurious timepiece, with a black ceramic bezel adorned with a Ceragold™ diving scale. The polished black ceramic dial includes laser-engraved waves and a date window at 6 o'clock. For a refined look, the skeleton hands and raised indexes are filled with bright Super-LumiNova, while the helium escape valve has been designed in a conical shape.

The timepiece is presented on a stainless steel and 18ct Sedna™ gold bracelet, and powered by the OMEGA Master Chronometer Calibre 8800, which can be seen in all its glory through the wave-edged caseback crafted of sapphire-crystal.
