Omega Seamaster Diver 300M 210.30.42.20.01.018 42 mm Steel Black Dial Watch

Touches of orange mark out reference 210.30.42.20.01.018: the Seamaster name, the central seconds hand and the four quarter indexes are all picked out in that colour against a black aluminium dial. Around it, a black oxalic anodised aluminium bezel ring carries a white Super-LumiNova diving scale on the 42 mm stainless steel case.

Rhodium-plated skeletonised hands and indexes glow with white Super-LumiNova, and the OMEGA logo is printed in white. A brushed steel mesh bracelet with foldover clasp completes the watch, and a sapphire crystal caseback shows the Co-Axial Master Chronometer calibre 8806, certified by METAS, resistant to 15,000 gauss and holding 55 hours of reserve; water resistance is 300 metres.
