Though all Rolex watches possess features and functions that surpass established watch quality standards, the Milgauss goes a step further with capabilities that make it a standout in the scientific community. The Milgauss was introduced in 1956 as a watch that can withstand exposure to high-level magnetic fields. In their line of work, scientists are exposed to magnetic fields of strengths that are significantly higher than those common in everyday life. Regular mechanical watches can be compromised by magnetic fields with strengths of 50 to 100 gauss, so they would be impacted even more by magnetic fields of 1,000 gauss, which is the magnitude of magnetic fields that scientists work with on a regular basis. Rolex’s solution to this issue was the development of the Milgauss model. With “mil” coming from the French “mille” for thousand and “gauss” being a measurement unit for magnetic flux density, the model name Milgauss means “1,000 gauss,” which is the maximum magnetic field level the watch is designed to withstand.
