The Omega Seamaster Diver 300M Co-Axial Master Chronometer reference 210.30.42.20.03.001 represents the 2018 evolution of the Seamaster Diver introduced in 1993 and worn by James Bond across nine films beginning with GoldenEye. The 2018 redesign reintroduced the laser-engraved wave pattern dial of the original 1993 reference while bringing the line into Omega's Co-Axial Master Chronometer era. The 42mm stainless steel case features a blue ceramic unidirectional rotatable bezel with white enamel diving scale, paired with a polished blue ceramic dial laser-engraved with the signature wave pattern and a date window at six o'clock. Applied luminous skeletonized hour and minute hands and the Seamaster's characteristic broad-arrow indices complete the dial. Powered by the in-house Omega Caliber 8800, a Co-Axial Master Chronometer certified by METAS for accuracy and 15,000-gauss magnetic resistance, with a 55-hour power reserve at 25,200 vibrations per hour across 35 jewels, silicon balance spring, and Co-Axial escapement. Water resistant to 300 meters with screw-down crown and helium escape valve, fitted on a brushed and polished stainless steel bracelet. 2021 production, pre-owned condition.
