Since 1993, the Seamaster Professional Diver 300M has earned a celebrated reputation. Today, the collection has retained the iconic marine heritage and been enhanced with OMEGA's most advanced technology and styling.
This 44 mm timepiece is designed for aquatic adventures, crafted from stainless steel and 18ct yellow gold with a polished blue ceramic bezel featuring a Ceragold™ diving scale. The pushers, as well as the wave-patterned dial with a date window at 6 o’clock, boast polished blue ceramic while the hands and indexes feature 18ct yellow gold and are filled with white Super-LumiNova.
The timepiece comes with a blue rubber band and is powered by the OMEGA Master Chronometer Calibre 9900, visible through the sapphire-crystal caseback featuring a wave-edged design.
