Hit List: Omega Seamaster Diver 300M Co-Axial Master Chronometer

A cornerstone of Omega’s 2018 introductions, the Seamaster Diver 300M line—introduced in 1993 and completely overhauled this year—now features a larger 42 mm case and a slew of aesthetic and technical updates, including a ceramic diving bezel, polished ceramic dial, and newly patented conical helium escape valve. The timepiece also has a hidden perk: its Master Chronometer Calibre 8800, known for its superior precision and magnetic resistance.
