OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M 210.32.42.20.01.006 is a dive watch with a 42 mm steel case. It measures 13.8 mm thick, with a lug-to-lug span of 49.7 mm, and carries a unidirectional rotating bezel. A domed sapphire crystal with antireflective treatment covers the black dial, and the screw-down crown works alongside a helium valve for saturation diving. Inside is the self-winding calibre 8806, a Master Chronometer movement certified by METAS with resistance to magnetic fields up to 15,000 gauss and a 55 hour power reserve. The rotor and bridges carry Geneva waves in arabesque, visible through the display back. An orange rubber strap with a steel folding clasp completes the watch. The screw-down crown helps hold the case to its 300 metre water resistance rating.
