In 1957, OMEGA released three professional timepieces; The Seamaster 300, the Railmaster and the Speedmaster. Today the Swiss brand is paying tribute to these three mechanical masterpieces by releasing special 60th Anniversary editions of each model. The “Broad Arrow” was not only the first Speedmaster, it was also the first chronograph wristwatch in the world with its tachymeter scale on the bezel as opposed to printed on the dial. The new 2017 Speedmaster stays true to the original design with its perfect match of the original '57 tachymeter. The 1957 Railmaster was designed for those working close to electrical fields; and though the new model retains the original's unpretentious style, its Master Chronometer 8806 movement takes antimagnetic to a whole new level, resisting fields of 15,000 gauss. The new Seamaster 300 features a black aluminium bezel and retains the famous Naïad sign on the crown, which back in '57 was a mark of exceptional water resistance. Each watch is limited to 3,557 pieces and is delivered inside a presentation box inspired by the original 1957 packaging, right down to the Seahorse on the lid, a retro logo and beige corduroy lining. The box also contains two spare straps; leather and NATO, as well as a tool to change them.
