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.

, 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.
