Since 1993, the Seamaster Professional Diver 300M has enjoyed a devoted following. Today's modern collection embraces this renowned maritime heritage and enriches it with OMEGA's innovative ideas and superior design. This 44 mm stainless steel chronograph features a polished black ceramic bezel with a white enamel diving scale. The pushers and dial are also crafted from polished black ceramic. The dial is further enhanced with laser-engraved waves and a date window at 6 o'clock. All hands and indices are rhodium-plated, with the central hands and indices additionally filled with white Super-LumiNova. Powered by the OMEGA Master Chronometer Calibre 9900, which can be admired through the sapphire crystal case back with its wave-edged design, this watch comes with a black rubber strap.
