Since 1993, the Omega 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 18K Sedna gold, and includes a blue ceramic bezel with a Ceragold diving scale. The dial is also made of polished blue ceramic and features laser-engraved waves, along with a date window at 6 o’clock. The skeleton hands and raised indexes are crafted from 18K Sedna gold and filled with white Super-LumiNova, while the helium escape valve features a conical design. The Omega Seamaster is presented on a stainless steel and 18K Sedna gold bracelet and is driven by the Omega Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.
