Additional Info: Based on an original design from the 1950s, the Rolex Milgauss is resistant to the extremes of magnetic environments. The automatic movement is protected by a magnetic shield mounted inside the case, providing resistance to magnetic fields up to the magnetic flux density of 1000 gauss. This timepiece is thus indispensable for scientists, engineers, and doctors – professionals who work close to devices that generate strong magnetic fields.The magnetic resistance is amplified in the Rolex Milgauss with the inclusion of a blue PARACHROM hairspring, which, in addition to being completely insensitive to magnetic fields, is extremely shock resistant.
