After discovering the alloys for assembling anti-magnetic watches, many watch-making brands utilize such materials in production in order to improve the performance of such timepieces.
In 1989 IWC first manufactured the Ingenieur Reference 3508, which was able to withstand huge magnetic fields of up to 500,000 A/m.
The Rolex Milgauss series of antimagnetic certified chronometers was first manufactured in 1954 with the model 6541 for those working in nuclear, aircraft, and medical settings associated with strong magnetic fields. The watch has an advertised magnetic flux density resistance of 1 000 gauss within magnetic fields of 80 000 A/m. In 2007, after being out of production for nearly two decades a new Milgauss was introduced as the model number 116400.
