OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M, reference 210.32.42.20.01.001, has a 42 mm steel case, a dive watch with a black dial. The case measures 13.56 mm thick with a lug-to-lug span of 49.9 mm, and a unidirectional rotating bezel surrounds the dial. A domed sapphire crystal with antireflective treatment on both sides covers the face. Inside is the self-winding calibre 8800, a Master Chronometer movement with Co-Axial escapement and resistance to magnetic fields up to 15,000 gauss, offering 55 hours of power reserve. The date sits on the dial, and a helium escape valve alongside the screw-down crown suits saturation diving. A sapphire-backed case allows a view of the movement. Black rubber strap fits with a steel pin buckle. Omega rates the case to 300 metres.
