Diver 300M Seamaster Steel Master Chronometer 210.30.42.20.01.018

Since 1993, the Seamaster Diver 300M has enjoyed a legendary following. For today’s modern collection, OMEGA has embraced that famous ocean heritage and updated it with the brand's most advanced innovation and design. This 42 mm model is crafted in stainless steel and includes a black oxalic anodized aluminium bezel ring with a diving scale in white Super-LumiNova. Black aluminium is also used to create the dial, which features rhodium plated skeletonized hands and indexes that are filled with white Super-LumiNova. The colour orange is used for the central seconds hand, the four quarter indexes, and Seamaster name, while the OMEGA logo is transferred in white. The watch is presented on a brushed mesh bracelet with clasp, and is driven by the OMEGA Co-Axial Master Chronometer Calibre 8806, which can be seen through the sapphire crystal caseback.
