For over 27 years, the Seamaster Professional Diver 300M has been highly esteemed by its fan base. This current iteration upholds the heritage of its predecessor while implementing OMEGA's most advanced technology and design.
This 44 mm chronograph model features 18ct Sedna™ gold construction and a black ceramic bezel ring adorned with a polished diving scale. The pushers are also polished black ceramic, and the dial displays laser-engraved waves in a positive-relief style along with a date window at 6 o'clock. The subdial rings and hands are crafted in 18ct Sedna™ gold, while the central hands and indexes are 18ct Sedna™ gold and filled with white Super-LumiNova.
A rubber strap holds the OMEGA Seamaster Diver 300M Co-Axial Master Chronometer in its 44mm black dial and 18ct rose gold casing, showcasing the power of the OMEGA Master Chronometer Calibre 9901 through its sapphire-crystal wave-edged caseback.
