OMEGA Seamaster Diver 300M

The Omega Seamaster Diver 300M 210.30.42.20.03.001 is a 42 mm steel dive watch with a blue dial. The case measures 13.56 mm thick and 49.9 mm between the lugs, with a unidirectional rotating bezel around the dial. A domed sapphire crystal with anti-reflective treatment on both sides covers the front. The self-winding Omega calibre 8800 drives the watch, a Master Chronometer movement certified by METAS with resistance to magnetic fields up to 15,000 gauss and a 55-hour power reserve. The date appears on the dial, and a transparent caseback shows the movement. A screw-down crown and helium valve are both fitted. On a steel bracelet with a foldover clasp, the case carries a 300 metre water resistance rating.
