Details

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 black oxalic anodized aluminium bezel ring with a diving scale in white Super-LumiNova. Black aluminium is also used to create the dial, which is laser-engraved with the Diver’s iconic wave pattern. The skeletonized hands and indexes are rhodium plated and filled with white Super-LumiNova, while the other markings, including the OMEGA logo, are 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.
