OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M, reference 210.52.42.20.04.001, is a dive watch with a 42 mm case in Sedna gold. The case measures 13.92 mm thick with a lug-to-lug span of 49.93 mm, and a unidirectional rotating bezel surrounds the white dial. A domed sapphire crystal with antireflective treatment on both sides covers the dial, and the display back reveals the self-winding calibre 8801, a Master Chronometer movement certified by METAS with a 55-hour power reserve. The date sits alongside a helium escape valve for saturation diving, and the screw-down crown adds security against water ingress. A brown rubber strap closes with a pin buckle in Sedna gold. The screw-down crown backs up the 300 metre water resistance rating.
