OMEGA Seamaster Diver 300M (Black Black)

Omega's Seamaster Diver 300M (Black Black), reference 210.92.44.20.01.003, comes in 43.5 mm black ceramic. The case measures 14.47 mm thick with a lug-to-lug of 51.5 mm, and a unidirectional rotating bezel surrounds the black dial. A domed sapphire crystal with antireflective treatment on both sides covers the dial. 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. A helium valve and screw-down crown mark this out as a dive watch, and the sapphire display back shows the finishing on the rotor and bridges. A black rubber strap with a ceramic pin buckle completes the watch, and the screw-down crown helps hold it to a 300 metre rating.
