Diver 300M Seamaster Sedna™ gold Master Chronometer 210.62.42.20.01.002

Since 1993, the Seamaster Professional Diver 300M has enjoyed a legendary following. Today’s modern collection has embraced that famous ocean heritage and updated it with OMEGA’s best innovation and design. This 42 mm model is crafted in 18K Sedna™ Gold and includes a black ceramic bezel with a Ceragold™ diving scale. The dial is also polished black ceramic and features laser-engraved waves and a date window at 6 o’clock. The skeleton hands are in 18K Sedna™ Gold and are filled with white Super-LumiNova, while the helium escape valve has been given a new conical design. The watch is presented on a black 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.
