About the Rolex Milgauss
The Rolex Oyster Perpetual Milgauss timepiece was originally released in 1956. It is a antimagnetic watch designed especially for those who worked at research labs, power plants, or medical facilities where electromagnetic fields can ruin the precise timing of a watch.
The precision of an any ordinary mechanical watch can be affected by a magnetic field of 50 to 100 gauss. However, many scientists are exposed to much higher magnetic fields during the course of their work. Rolex’s solution was to create the Milgauss, the first watch of its kind. The current model Milgauss launched in 2007 is equipped with a non-magnetic alloy Parachrom-Blu hairspring and Rolex movement encased by a magnetic shield. Hence the name Milgauss which is derived from the Latin mille, which means one-thousand, and gauss, the unit of a magnetic field. The Milgauss lives up to its name because it can withstand a magnetic field of up to 1,000 gauss. Aside from its incredible resistance to magnetic fields, the Milgauss' most notable feature is an orange lightning-bolt second hand which Rolex originally introduced with the 6541 Milgauss model.
