The Rolex Milgauss and its Scientific Connection

Rolex has created a watch for many exciting professions, such as the avid pilot, diver, and sailor. Not wanting to leave any profession out, Rolex introduced the Rolex Milgauss in 1957, made specifically for scientists. During the 1950’s, the United States saw a significant increase in government funding for scientific research, as well as public support for scientific projects. This can largely be attributed to the public’s awareness of the role science played in ending World War II. It was also the time the United States began a big push for space exploration.

So, Rolex decided to take advantage of science’s growing popularity and created a luxury watch specifically for those working in science related fields.  What makes this watch so uniquely special is its ability to withstand magnetic fields of up to 1000 Gauss.

How the Milgauss Fends Off Electromagnetic Exposure

Exposure to electromagnetic waves was common for workers in power plants and medical and research labs. These waves interfere with the time-keeping of luxury watches and can mess with the alignment of the balance wheel and hairspring. All of this negatively affects the accuracy of the watch. On the Milgauss, a magnetic shield protects the case and the movement of the watch. Therefore, this helps the watch withstand the electromagnetic waves. Its called a Faraday cage since it contains ferromagnetic alloys.

There are many features of the Milgauss that set it apart from other Rolex models. One of the most notable features is its orange, lightning bolt second hand, which matches the seconds markings along the outside of the dial and contrasts well with the black dial. It is only available in stainless steel, as steel is resistant to corrosion. Unlike the other Rolex models, the Rolex Milgauss features a smooth, polished bezel. The Milgauss is similar in size to the Rolex Submariner, coming in just a little bit thicker. In addition to being useful in labs and plants, the design and style of the Rolex Milgauss also makes it a great dress watch. The smooth bezel along with the simple dial give it a sophisticated look that makes it the perfect accessory with any dress suit.

2007 to the Present

In 2007, Rolex introduced a new version of the Rolex Milgauss. Suprisingly, they introduced three versions: one with a white dial, one with a black dial, and one with a black dial and green tinted sapphire crystal. Production of the Milgauss ended in 1988, making it a rare Rolex model and increasing its value. Vital to this new design is the Paracrhom Blu hairspring. The Faraday cage protects the movement from magnetic waves up to about 800 gauss. The new hairspring and the escape, when its made of amorphous nickel phosphor, offer the last bit of protection. The latest Rolex Milgauss model was one of the small number of Rolex watches to feature this hairspring.

Rolex has a reputation for creating innovative and unique pieces. Rolex was the first brand to introduce a watch with a waterproof case, created the first watch to have a date and day that automatically changed, and was the first watchmaker to earn a chronometer certification. The Rolex Milgauss continues this tradition of excellence with its innovative features and uses. The two features that set the Rolex Milgauss apart are its orange lightning bolt second hand and the Parachrom Blu Hairspring that protects it from magnetic waves.  Rolex watches possess useful functions. They are elegantly designed and masterfully crafted. Rolex watches, specifically the Rolex Milgauss, are truly one of a kind.
