Antimagnetic watches were developed to be used by scientists, electrical and railway engineers and technicians. The Railmaster model was in production between 1957 and 1963, and it is part of the same highly sought after series as the Omega Speedmaster and Omega Seamaster 300 divers watch.
The first antimagnetic watch was the Ingenieur model introduced by IWC in 1955. Omega introduced its Railmaster model in 1957, and Rolex brought its Milgauss model to the market in 1958. The movement of the Railmaster was protected against magnetism on all sides. The thick dial was made of mu-metal, the crown was a tightly sealed Naiad special crown, and the movement was also surrounded by a protective mu-metal casing. This structure protected the watch against magnetic fields up to 1,000 gauss.
