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 stainless steel model includes a polished black ceramic bezel and the dial is also polished black ceramic and features laser-engraved waves. 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.
