Seamaster Diver 300m Co‑Axial Master Chronometer 42mm O21030422004001

 
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 from stainless steel and includes a black ceramic bezel with a white enamel diving scale. The dial is polished white ceramic and features laser-engraved waves and Seamaster highlighted in red.

The polished, blackened skeleton hour and minute hands are filled with white Super-LumiNova. The seconds hand features a varnished red tip.

The watch is presented on a polished-brushed stainless steel bracelet and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.
