    OMEGA Seamaster Diver 300M - (Ref. O21030422003001) Product Details

    The modern iteration of the pioneering 1957 original Seamaster 300 - OMEGA’s classic dive watch, refined 007’s timepiece of choice for over 25 years Unparalleled precision from the Master Chronometer Calibre 8800 movement 42mm case in stainless steel with ceramic bezel and dial The Bond Watch The Seamaster Diver 300M, the modern iteration of 1957’s Seamaster 300, first launched in 1993, proudly bearing the now-iconic Professional inscription on its signature blue dial. This iconic piece quickly earned the moniker ‘The Bond Watch’ after its use by the world's most famous spy, being equally at ease for missions requiring high-octane action and those requiring dry martinis. The exceptional sailing and diving provenance of OMEGA is enhanced in the modern collection with the latest technical innovations and a careful evolution of the Seamaster’s timeless design. Industry-leading precision This 42mm model is crafted from stainless steel with a black ceramic bezel featuring a hard-wearing white enamel diving scale. The classic navy blue ceramic dial is laser-engraved with the famous Seamaster wave pattern and a date window at 6 o’clock completes the classic design. The skeleton hands and raised indexes are rhodium-plated and inlaid with white Super-LumiNova, while the helium escape valve has been given a conical design for both ease of use and updated aesthetics. The watch is presented on a stainless steel bracelet and is driven by the OMEGA Master Chronometer Calibre 8800, visible through the sapphire crystal on the caseback, surrounded by OMEGA’s signature wave edges.
