Diver 300M Seamaster Sedna™ gold Master Chronometer 210.62.44.51.01.001

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 44 mm chronograph model is crafted from 18K Sedna™ gold and includes a laser-ablated black ceramic bezel ring with a polished diving scale. The pushers are also polished black ceramic, as well as the dial, which features laser-engraved waves in a positive relief and a date window at 6 o’clock. The subdial rings and hands are in 18K Sedna™ gold, while the central hands and indexes are 18K Sedna™ gold and filled with white Super-LumiNova. The watch is presented on a rubber strap and is driven by the OMEGA Master Chronometer Calibre 9901, which can be seen through the sapphire-crystal on the wave-edged caseback.
