Diver 300M Seamaster Sedna™ gold Master Chronometer 210.52.42.20.04.001

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 18K Sedna™ Gold and features a diving scale on the bezel in positive relief. The dial is matte white ceramic and includes polished waves in positive relief, a date window at 6 o’clock, as well as 18K Sedna™ Gold skeleton hands and indexes that are filled with white Super-LumiNova. The watch is presented on a brown rubber strap and is driven by the OMEGA Master Chronometer Calibre 8801, which can be seen through the sapphire-crystal on the wave-edged caseback.
