The Rolex Milgauss was launched in 1954, as the first Rolex watch to shield a movement from magnetic fields. Created for scientists, engineers, and technicians, whose watches used to be damaged by magnetism, the Milgauss is resistant to magnetic fields up to 1,000 gauss. In 2007, Rolex relaunched the Milgauss with a playful, unexpected design, possessing a green sapphire crystal, and orange thunderbolt hands and index markers.
