OMEGA Seamaster Diver 300M

Omega's Seamaster Diver 300M ref. 210.62.44.20.01.001 is a dive watch with a 43.5 mm case in 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, and a display back shows the movement. Inside is the self-winding calibre 8806, a Master Chronometer certified movement with a silicon balance spring and 55 hours of power reserve. The case is fitted with a helium valve and a screw-down crown, both practical for diving use. It comes on a black rubber strap with a ceramic pin buckle. The screw-down crown helps hold the case to its 300 metre water resistance rating.
