Since 1993, the Seamaster Professional Diver 300M has achieved notoriety and gained a legion of devotees. The current collection has maintained the iconic marine heritage while incorporating OMEGA's cutting-edge technology and design elements.
This 42mm creation is crafted from stainless steel and features a blue ceramic bezel with a white enameled diving scale. The dial is polished blue ceramic and includes laser-engraved waves and a 6 o'clock date window. The skeleton hands and elevated indexes are luminous rhodium-plated and filled with white Super-LumiNova, and the helium escape valve is conically designed.
This timepiece is housed in a stainless steel bracelet and the OMEGA Master Chronometer Calibre 8800 can be viewed from the sapphire-crystal, wave-edged caseback.
