Diver 300M Seamaster Steel Master Chronometer 210.30.42.20.06.002

Since 1993, the Seamaster Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s most advanced innovation and design. This 42 mm model is crafted in stainless steel and includes a grade 5 titanium bezel with a laser-ablated diving scale in positive relief and a single dot of white Super-LumiNova at 12 o’clock. PVD stainless steel is used to create the brushed dial as well as the polished and skeletonized hands and indexes, which are filled with white Super-LumiNova. Other markings, including the OMEGA logo, are transferred in black. 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.
