OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M, reference 210.22.42.20.03.002, is a dive watch with a 42 mm case in steel and Sedna gold. The case measures 13.56 mm thick with a lug-to-lug span of 49.9 mm, and a unidirectional rotating bezel frames the blue dial. A domed sapphire crystal with anti-reflective treatment on both sides covers the dial, and a helium escape valve sits beside the screw-down crown. The Omega calibre 8800 drives the watch, a self-winding movement certified as a Master Chronometer with resistance to magnetic fields up to 15,000 gauss and 55 hours of power reserve. A transparent caseback shows the movement, and the date appears on the dial. The blue rubber strap closes with a steel pin buckle. Water resistance is rated to 300 metres.
