OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M ref. 210.62.42.20.01.003 is a dive watch in yellow gold, 42 mm across. The case measures 13.72 mm thick with a lug-to-lug span of 49.93 mm, and its unidirectional rotating bezel surrounds a black dial. A domed sapphire crystal with antireflective treatment on both sides covers the dial. Inside is the Omega calibre 8801, a self-winding Co-Axial movement certified as a Master Chronometer with a 55 hour power reserve. The date function sits alongside a helium valve for saturation diving, and a screw-down crown adds security. A transparent caseback shows the movement. Fitted to a black rubber strap with a pin buckle in matching gold, the case carries a 300 metre water resistance rating.
