This Omega Seamaster 300M Chronograph model features a case sized at 44mm, crafted from stainless steel and 18ct Sedna™ gold and features a polished black ceramic unidirectional rotating bezel with a Ceragold™ diving scale.

For the caseback, wave detailed stainless steel and scratch-resistant sapphire crystal is used, enabling the wearer to see the impressive Omega movement while incorporating the famous ocean heritage.

A standout feature on this chronograph model are the polished black ceramic pushers that perfectly match the black ceramic dial. The laser-engraved wave patterned dial features luxurious 18ct Sedna™ gold detailing, including the highly luminous Super-LimiNova filled hands and indexes. A handy date window can also be found at the 6 o'clock position.

Finally, the Omega Seamaster Diver 300M Chronograph comes presented on the black rubber strap and is powered by Omega's Master Chronometer Calibre 9900.
