Rolex Milgauss

The name of the Milgauss is derived from the French word “mille” = “thousand” and “Gauss”, the unit of magnetic flux density. It simply means that the clock runs reliably even in magnetic fields up to 1,000 Gauss. The functionality and precision of an ordinary mechanical watch can be impaired by a magnetic field of 50 to 100 Gauss. Many (experimental) researchers are exposed to strong magnetic fields during their work.

In 1956, the Milgauss was therefore presented as an ideal watch for researchers in particular. Using it, researchers, such as the staff of the European Center for Nuclear Research (CERN), could finally wear a wristwatch during their work. Some important components of the new Milgauss movement are made from innovative paramagnetic materials, including the blue Parachrom hairspring. They were developed and manufactured internally using state-of-the-art technology.
