Seamaster Diver 300M Omega Co‑Axial Master Chronometer 42 mm
Steel on rubber strap
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 also polished black ceramic and features laser-engraved waves and a date window at 6 o’clock.
The skeleton hands and raised indexes are rhodium-plated and are filled with white Super-LumiNova, while the helium escape valve has been given a conical design.
The watch is presented on a black rubber strap and is driven by the OMEGA Master Chronometer Calibre 8800, which can be seen through the sapphire-crystal on the wave-edged caseback.
All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.
