OMEGA Seamaster Diver 300M (Summer Blue)

The Omega Seamaster Diver 300M (Summer Blue), reference 210.30.42.20.03.003, is a dive watch with a 42 mm steel case. The case measures 13.56 mm thick with a lug-to-lug of 49.9 mm, and a unidirectional rotating bezel surrounds the blue dial. A sapphire crystal with antireflective treatment on both sides covers the dial, domed and scratch-resistant. Inside is the self-winding Omega calibre 8800, a Master Chronometer movement with a Co-Axial escapement and resistance to magnetic fields up to 15,000 gauss, running for 55 hours on a full wind. The date sits alongside a helium escape valve, useful for saturation diving, and the screw-down crown adds security. A steel bracelet with a foldover clasp featuring comfort setting and diver extension closes the watch. Water resistance reaches 300 metres, or 30 bar.
