OMEGA Seamaster 300

Omega's Seamaster 300, reference 234.92.41.21.10.001, is a dive watch with a 41 mm bronze case. The case measures 14.4 mm thick with a lug-to-lug span of 48 mm, and a unidirectional rotating bezel surrounds the brown dial. A domed sapphire crystal with antireflective treatment inside covers the dial, protecting the self-winding calibre 8912 beneath. This Master Chronometer movement is certified by METAS, resists magnetic fields up to 15,000 gauss, and stores 60 hours of power reserve. The screw-down crown and display back are both present, the latter revealing the movement's Geneva waves in arabesque finish. A brown non-grained calf leather strap closes with a bronze pin buckle. The screw-down crown helps hold the case to its 300 metre water resistance rating.
