The Rolex Milgauss, introduced in 1956, was designed specifically for professionals working in environments with high magnetic fields, such as scientists and engineers. Its name, “Milgauss,” comes from the combination of “mille,” meaning thousand in French, and “gauss,” a unit of magnetic flux density. The watch was engineered to withstand magnetic fields of up to 1,000 gauss, making it a breakthrough in the field of anti-magnetic timepieces.

The original Milgauss featured a 38mm case and a self-winding movement protected by a soft iron inner case, which shielded the movement from magnetic interference. In 2007, Rolex introduced an updated version with a larger 40mm case and a distinctive green sapphire crystal, giving the watch a modern, unique look. Despite its specialized design, the Milgauss remains a versatile and stylish choice, combining Rolex’s signature craftsmanship with cutting-edge technology. It remains a popular model for those seeking both durability and distinctive design.
