Omega Seamaster Diver 300M Co-Axial Master Chronometer Watch - 42 mm Steel And Sedna Gold Case - Unidirectional Bezel - Black Ceramic Dial - 210.20.42.20.01.001

Beneath the polished black ceramic dial of reference 210.20.42.20.01.001 beats Omega's Co-Axial Master Chronometer caliber, delivering anti-magnetic resistance to 15,000 gauss and chronometer-certified precision that surpasses COSC standards. The 42mm ceramic case construction represents a significant departure from traditional steel dive watches, offering scratch resistance and lightweight comfort that competitive divers and collectors have embraced since this configuration's introduction. Sedna gold accents throughout the case architecture create visual depth against the monochromatic ceramic foundation, while the unidirectional timing bezel maintains the professional dive tool credentials that define the Seamaster Diver 300M lineage.
