The Oyster Perpetual Milgauss, the watch par excellence of technological and scientific progress launched in 1956, reconciles strong magnetic fields and chronometric precision. Created in 1956 for engineers and technicians who are exposed in their work to magnetic fields which disrupt the performance of mechanical watches, the Milgauss was designed to resist strong interference of up to 1,000 gauss thanks to a magnetic shield patented by Rolex protecting the movement. Hence the name of the watch, mille being French for thousand. The Milgauss became known notably as the watch worn by scientists at the European Organization for Nuclear Research (CERN) in Geneva. A new generation of this watch, introduced in 2007, encompasses all Rolex’s technological and watchmaking expertise. Aesthetically, the new Milgauss stands out with its orange seconds hand shaped like a lightning bolt, which was inspired by the original model. The watch also features a green sapphire crystal, a novelty in watchmaking.
