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 44 mm chronograph model is crafted from stainless steel and includes a polished black ceramic bezel with a white enamel diving scale. The pushers are also polished black ceramic, as well as the dial which features laser-engraved waves and a date window at 6 o’clock.

The subdial hands are rhodium-plated, along with all other hands and indexes which are filled with white Super-LumiNova.

The watch is presented on a stainless steel bracelet and is driven by the OMEGA Master Chronometer Calibre 9900, which can be seen through the sapphire-crystal on the wave-edged caseback.
