OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M ref. 210.92.42.20.01.003 is a dive watch with a 42 mm bronze case. The case measures 13.8 mm thick and 49.7 mm between the lugs, with a unidirectional rotating bezel. A domed sapphire crystal with antireflective treatment covers the black dial. Inside is the self-winding calibre 8806, a Master Chronometer movement with a 55-hour power reserve. The screw-down crown works alongside a helium valve for saturation diving, and the display back shows the rhodium-plated rotor. A black rubber strap closes on a bronze pin buckle. The case carries a 300 metre water resistance rating.
