Omega Seamaster Diver 300M Co‑Axial Master Chronometer 42mm Steel on Steel
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 blue ceramic bezel with a white enamel diving scale. The dial is sun-brushed PVD chrome colour ceramic and features laser-engraved waves and a date window at 6 o’clock.
The skeleton hands and raised indexes are blued and filled with white Super-LumiNova, while the helium escape valve has been given a conical design.
The watch is presented on a 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.
