Since 1993, the OMEGA Seamaster Professional Diver 300M has stood as an icon of marine precision and adventurous spirit. Today’s modern collection reimagines that legacy, combining OMEGA’s signature innovation with timeless design.
This 42 mm stainless steel timepiece commands attention with its black ceramic bezel, accented by a white enamel diving scale. The polished black ceramic dial, engraved with intricate waves, is complemented by a date window at 6 o’clock, marrying elegance with practicality.
Rhodium-plated skeleton hands and raised indexes, filled with Super-LumiNova, ensure visibility in any light, while the reimagined conical helium escape valve offers both style and professional utility. Beneath its refined exterior beats the OMEGA Master Chronometer Calibre 8800, visible through a sapphire-crystal wave-edged caseback. METAS-certified, this movement delivers extraordinary precision, magnetic resistance, and reliability.
