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.
Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
