Since 1993,
the Seamaster Professional Diver 300M has earned a loyal and legendary following. Today’s modern collection embraces that storied oceanic heritage and updates it with OMEGA’s finest innovations and design. This 42 mm model is crafted in stainless steel and 18K Sedna™ gold
and features a black ceramic bezel with a Ceragold™ diving scale. The dial is also polished black ceramic and displays laser-engraved waves and a date window at 6 o’clock. The skeletonized hands and raised indices are 18K Sedna™ gold and filled with white Super-LumiNova,
while the helium escape valve has been given a conical design. The watch is presented on a stainless steel and 18K Sedna™ gold bracelet and is powered by Caliber OMEGA Master Chronometer 8800,
visible through the sapphire crystal caseback with wavy edges.
