Rolex Milgauss

The Rolex Oyster Perpetual Milgauss is a highly collectible model introduced by Rolex in 1956 with the model number 6451. The Milgauss was designed as antimagnetic watch specifically for those who worked in power plants, medical facilities and research labs (like those in Geneva) where electromagnetic fields can cause havoc with the timing of a watch. The current model Milgauss is equipped with amagnetic alloy (Parachrom-Blu) hairspring and movement encased by a Faraday cage. The name Milgauss is derived from the Latin mil, which means one-thousand, and gauss, the unit of a magnetic field. This model is so named because it can withstand a magnetic flux density of 1,000 gauss.

The original Milgauss was very similar to the appearance of the Rolex Submariner, with an over-sized case and bezel, with the Twinlock crown, and a riveted Oyster bracelet. Although the Milgauss only went through two different models (6541, 1019) the Milgauss went through numerous configuration changes before being discontinued in 1988.
