OMEGA Seamaster Diver 300M

Omega presents the Seamaster Diver 300M, reference 210.20.42.20.01.001, a dive watch with a 42 mm case in steel and Sedna gold. The case measures 13.56 mm thick with a lug-to-lug of 49.9 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 beneath. Inside sits the self-winding calibre 8800, a Master Chronometer with 55 hours of power reserve. The date function pairs with a helium escape valve and screw-down crown, both useful for diving. It comes on a matching steel and Sedna gold bracelet with a foldover clasp and diver extension. The screw-down crown backs up a rating of 300 metres.
