The Omega Railmaster was launched in 1957, as part of the professional trilogy, along with the Seamaster 300 and the Speedmaster.
The Speedmaster was intended for pilots, the Seamaster for divers, and the Railmaster was specifically designed for professionals (such as engineers) working in a magnetic environment.
To meet this purpose, i.e. to protect its movement against the harmful effects of magnetism, the Railmaster reference CK 2914, then ST 135.004 was built as a protective cage, with a thicker dial and a special case in ferromagnetic nickel-iron alloy.
