Omega Seamaster Diver 300M Co-Axial Master Chronometer Watch - 42 mm Steel And Sedna Gold Case - Unidirectional Bezel - Blue Ceramic Dial - 210.20.42.20.03.002

Powered by Omega's Co-Axial Master Chronometer movement, this polished blue ceramic dial Seamaster combines the brand's revolutionary escapement technology with METAS-certified antimagnetic resistance up to 15,000 gauss. The 42mm ceramic case construction of reference 210.20.42.20.03.002 represents a significant departure from traditional steel sports watches, offering superior scratch resistance and lightweight comfort on the wrist. Beneath the sapphire crystal lies a dial that captures light with the distinctive depth only achievable through ceramic's unique reflective properties, while the unidirectional timing bezel maintains the essential functionality that has defined the Diver 300M series since its introduction.
