Rolex. A fine stainless steel self-winding water-resistant anti-magnetic wristwatch with sweep centre seconds and bracelet

The Milgauss model was designed for use in areas of high electro-magnetic fields found in laboratories and electro-engineering. One of the most distinctive of all Rolex 'Sports' models, the 1019 was the last 'tool' watch designed for a specific activity to be made by the renowned firm. In production from 1966 to 1990, the model 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 to 70-90 Gauss whereas the Milgauss keeps its incredibly precision in a magnetic field up to 1000 Gauss.
