The Rolex Milgauss

In the middle of the 20th century, the world was abuzz with innovation, science, and technology like never before. It was the time of the space race, but we were also discovering how the universe works through even the tiniest particles. Science and this age of discovery inspired Rolex, and thus the spirit of the Milgauss was born.

What Does Milgauss Mean?

The Rolex Milgauss is known as the scientist’s luxury watch, as a Rolex timepiece that can withstand magnetic fields up to 1000 Gauss, as many scientists are exposed to higher fields than normal. The first generation developed in 1956, the name Milgauss originates from the the French “mille”, meaning “thousand”, and the magnetic field measurement of Gauss. The CERN (European Council for Nuclear Research) was one of the first scientific institutions to confirm that the Rolex Milgauss could resist the powerful magnetic fields. Other mechanical watches can be affected by a field of 50 to 100 gauss.

Shield System

The innovative shield that protects the new generation’s 3131 calibre mechanical movement is what gives the Rolex Milgauss its resistance to magnetic interferences, marked by a special case back. Made of ferromagnetic alloys, this shield’s two components are screwed to the Rolex movement and then also to the Rolex Oyster case. You are affected by magnetic fields in everyday life, from office equipment to low-grade magnets. While they are not damaging to your watch, the continuous exposure to magnetic fields can interfere with the normal function and accuracy of your mechanical movement by way of the hairspring.

The Parachrom Hairspring

As part of Rolex’s pursuit of perfection, they are known to be some of the most precise time-keeping mechanisms in the world and the Rolex Milgauss is no exception. The hairspring is usually made of ferromagnetic alloys, a material that is prone to alteration from shock or magnetic fields. Rolex found this lack of reliability unacceptable and dedicated five years of research to create the blue Parachrom hairspring. The new hairspring proved to be 10 times less susceptible to shocks and unaffected by magnetic fields, as it is made from paramagnetic alloy, assuring you the accuracy of your Rolex.

Oyster Bracelet

Featuring the three-piece link Oyster bracelet, the Milgauss is outfitted for comfort and function. Invented by Rolex, the Rolex Easylink is an extension system that folds out of the Oyster bracelet to allow an increase of about 5mm for sizing around your wrist. This allows for maximum comfort to be regained, as your wrists can expand to anything from an increase in temperature to any certain physical activity.



904L Stainless Steel

904L stainless steel is used for the chemical industry since maximum resistance to corrosion is crucial to the value and durability of your Rolex. Used for the the Milgauss’s steel watch case, the domed bezel, and bracelet, Rolex uses this super alloy for that reason and also its ability to be highly polished. You can learn more about 904L steel and other materials Rolex uses in this previous post.

Milgauss Aesthetics

The Rolex Milgauss is instantly recognizable with its smooth lines and orange seconds hand shaped like a lightening bolt, an ode to the original model developed in the 1950s. The Chromalight display on the dial has a distinctive blue glow, which can last up to eight hours, nearly twice as long as that of standard luminescent materials. Even the simplicity of the Rolex green sapphire crystal placed on the Rolex Milgauss is what always makes the Rolex timepieces extraordinary.
