OMEGA Seamaster Diver 300M

The Omega Seamaster Diver 300M, reference 210.32.42.20.06.001, is a dive watch with a 42 mm steel case. It measures 13.56 mm thick with a lug-to-lug span of 49.9 mm, and a unidirectional rotating bezel surrounds the grey dial. The domed sapphire crystal has antireflective treatment on both sides. Inside is the self-winding calibre 8800, a Master Chronometer movement certified by METAS with a silicon balance spring and 55 hours of power reserve. The date function sits on the dial, and the case has a helium escape valve alongside a screw-down crown. A transparent caseback shows off the movement's Geneva waves finish. The watch comes on a blue rubber strap with a steel pin buckle, and the screw-down crown backs up the 300 metre water resistance rating.
