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 black leather strap. In keeping with the original Railmaster’s easy-to-read display, the dial of this model is grey with a black gradient, and features large numerals and hour markers in white Super-LumiNova. This watch continues the Railmaster’s legacy of anti-magnetism, courtesy of the Co-Axial Master Chronometer Calibre 8806. The movement is resistant to magnetism up to 15,000 gauss, and can be viewed through the transparent sapphire crystal on the caseback.38mm stainless steel caseBetween lugs - 19mmLug to lug - 44.9mmThickness - 12.4mmGrey dialDomed, scratch-resistant sapphire crystal with anti-reflective treatment insideScrew-in crownAnti-magneticChronometerTransparent casebackMaster Chronometer CertifiedOMEGA Caliber 8806, self-winding movement55 Hour power reserveBlack leather strap with fold over clasp closureWater resistance: 15 bar (150 meters / 500 feet)OMEGA Style #: O23512382006001...
