Railmaster Seamaster Steel Master Chronometer 235.12.38.20.13.001

The original OMEGA Railmaster was launched in 1957 for professionals working on the railways. For this modern update, OMEGA has retained that same timeless look while updating the design with a new colour and a modern standard of precision. The symmetrical 38 mm case is brushed and polished, and is presented on a golden brown Novonappa leather strap. In keeping with the original Railmaster’s easy-to-read display, the dial of this model is beige with a black gradient, and features large numerals and hour markers in vintage Super-LumiNova. There is also a Small Seconds display placed at 6 o’clock, which includes a beige varnished hand. This watch continues the Railmaster’s legacy of anti-magnetism, courtesy of the Co-Axial Master Chronometer Calibre 8804. The movement is resistant to magnetism up to 15,000 gauss, and can be viewed through the transparent sapphire crystal on the caseback.
