The Rolex Milgauss

The Rolex Milgauss

Introduced in 1954, the Rolex Milgauss is one of the most desirable models for all watch collectors. It is a unique model as it has been specially designed for people working in power plants and research labs. Resistant to a magnetic flux density of 1,000 gauss, this watch is meant for highly magnetic environments.

What Made Rolex Come Out With Milgauss?

Like its other special watches (Tool Models) such as Explorer, Explorer II, GMT-Master, Submariner, and Sea-Dweller that cater to people in specialized fields, the Rolex Milgauss was rolled out with an objective to serve a specific niche--those people who had to work amidst strong electromagnetic fields. As electromagnetic fields hamper the accuracy of normal watches, Rolex designed a special watch equipped with an appropriate defense mechanism to resist electromagnetic fields.

Features of the Rolex Milgauss

Rolex equipped this special model with a movement that contained anti-magnetic alloys and was also encased with an iron shield known as the Faraday cage or Faraday shield (named after physicist Michael Faraday). This shield provided a protective wall against external static electrical fields. Thus, it was the first perfect anti-magnetic watch with a magnetic intensity rating of 1000 oersted. This made Rolex name the model "Milgauss" derived from the French word mille, which means one thousand and gauss that means the unit of magnetic flux density.

Only two Milgauss models were created by Rolex as described below:

Model 6541: This was the first Milgauss model introduced in 1954. Its over-sized case, bezel, and dial were similar to that of the Rolex Submariner. It also featured leaf-shaped hands, a twinlock crown, a riveted construction Oyster bracelet, and a caliber 1065M movement.

Model 1019: This model was different from the previous model in that it exhibited a plain, smooth-finished bezel in place of the Submariner's bezel lookalike. Also, the name "Milgauss" was engraved on the dial under the 12 o'clock position, unlike in the previous model where it appeared just above the 6 o'clock position.

Over the years, many changes took place in the hands. The early leaf-shaped hands were replaced by the Mercedes-style hands with lightning bolt seconds. In subsequent years, they were again replaced by yet another new style: stick-shaped hands.

Nearly twenty years after this model had been discontinued, in 2007 Rolex decided to start its production all over again.

Currently Available Models of Oyster Perpetual Milgauss

Self-winding and waterproof to a depth of 330 feet, this unique Rolex watch is available in steel; black and white dials are the two popular dial options in this model. It comes with the popular Oysterlock bracelet with easy links. You will not find jewelry embedded on the bezel of the Milgauss as this model usually only features a polished bezel--although some Milgauss models use a beautiful green sapphire crystal.
