OMEGA Seamaster 300M Chronograph 44mm Black Watch

Keanes Code: 5233046


The Seamaster Professional Diver 300M, a legendary watch since 1993, combines ocean heritage with OMEGA's innovation.

This 44mm chronograph blends stainless steel and 18K Sedna™ gold, featuring a black ceramic bezel with Ceragold™ diving scale. The polished black ceramic dial displays laser-engraved waves and a date window at 6 o'clock. Subdial hands and indexes glow with white Super-LumiNova, all complemented by a black rubber strap.

Its precision is powered by the OMEGA Master Chronometer Calibre 9900, visible through the sapphire-crystal caseback, adorned with waves. This modern collection continues the legacy of a beloved diver's watch.
