OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M ref. 210.62.42.20.01.002 is a dive watch cased in 42 mm of Sedna gold. The case measures 13.72 mm thick with a 49.9 mm lug-to-lug span, and a unidirectional rotating bezel surrounds the black dial. A domed sapphire crystal with antireflective treatment on both sides covers the dial, and a sapphire caseback shows the movement. Inside is the self-winding calibre 8801, a Master Chronometer certified movement resistant to magnetic fields up to 15,000 gauss, with a 55 hour power reserve. The date sits alongside a helium escape valve, useful for saturation diving. A screw-down crown secures the case, and the watch is fitted on a black rubber strap with a Sedna gold pin buckle. Water resistance reaches 300 metres.
