The Rolex Milgauss was introduced in 1954 specifically to meet the needs of researchers, engineers and scientists exposed to higher than average electromagnetic fields in their lines of work; fields that would wreck havoc on the mechanisms of the average wristwatch. To protect the timepiece, Rolex resorted to the use of an anti-magnetic iron enclosure known as a Faraday Cage. As a result, the watch is able to withstand a magnetic field strength of 1,000 gauss (up to 4,000 times stronger than that of planet Earth!). The Milgauss has undergone various design modifications throughout the years. Today, the new model flaunts some pretty unique features, including the recognizable orange lightning bolt seconds hand fans adore, a green sapphire crystal, and more advanced paramagnetic components that protect the inner workings of the watch. The simple and symmetrical look of the Milgauss make it ideal for those who prefer a quiet, yet elegant appearance.
