ROLEX. A FINE STAINLESS STEEL AUTOMATIC ANTI-MAGNETIC WRISTWATCH WITH SWEEP CENTRE SECONDS AND BRACELET

The Milgauss model was designed for use in areas of high electro-magnetic fields, as found in laboratories or electro-engineering environments. In production from 1966 to 1990, reference 1019 is the successor of the 6543 and 6541, which belongs to the first generation of Milgauss series, and was only available in stainless steel. Its name is derived from the Greek "Mil" for thousand and "Gauss", the unit to measure magnetism. A normal watch movement can withstand up to 70-90 Gauss, whereas the Milgauss keeps its incredible precision in a magnetic field up to 1000 Gauss.
