Rolex released a new version of the Milgauss in 2007, with a number of dials with an orange second hand above it. To understand why they would add this function, one must first immerse his toes in the history behind the Milgauss. As a professional series replica watch, the Milgauss was developed with specific occupations in mind, power plants, scientists and doctors to be specific. Of these professions it is known that they get to see a reasonable part of the exposure to electromagnetic fields, so keeping a normal watch normal is a bit difficult. Enter the replica Milgauss, which can withstand up to 1,000 gausses, thanks to the addition of an innovative Faraday cage around the movement. The incredible history is reflected on the dial through the second hand of the lightning flash, a feature that is highly sought after by many replica Rolex collectors.
A bit of history
The Milgauss reference 6541 was introduced in 1956 and it was one of the first wristwatches capable of keeping time accurate when exposed to strong magnetic fields thanks to the soft, iron inner cover. This was actually the second Milgauss, after the ref. 6543 (despite the reference numbers, ref 6543 actually came first), that was a watch Rolex made in very small numbers, and which is little resemblance to later models.
The design of the Milgauss was in the first instance comparable to another professional Rolex replica model that is known for its resistance to water, not for magnetism. Like the Submariner, the Milgauss was presented in a stool made of steel, which technically became a sports replica watch, and like the Submariner it had a graduated rotating rim, bubble indices (in certain places) and perhaps most important of all ( for collectors) a single line of red text indicating the name of the model.
Rolex tackled this problem in the 1950s with the introduction of the Oyster Perpetual Milgauss model. The name comes from the French king Gauss, referring to the protection of the watch against magnetic fields up to 1000 gauss (named after physicist Karl Friedrich Gauss, a gauss is a unit for measuring the strength of a magnetic field). This level of magnetism, which corresponds to 0.1 Tesla or 80,000 vph, is 100 times higher than that of a typical horseshoe magnet. It would need levels like those found in an MRI scanner to influence the functioning of the watch. After devoting a lot of time and effort to the development of the recent reissue of the Milgauss, Rolex introduced it at the Baselworld waiting fair in 2007. The inner cover, made of ferromagnetic material, protects the movement against magnetic fields and consists of only two parts: a container and another lid firmly screwed to it. The container encloses the movement sideways and on the side of the dial, while the rear side seals the movement side. In order to ensure that the movement was protected as much as possible, the designers only left a minimum of openings in the dial and the housing. For example, there is no aperture for a date display. There are only the necessary small openings for the wrapping shank and for the shafts that anchor the hands. There are also two small holes for the screws holding the dial. Most other watches with magnetic protection have an inner housing with three parts, with the parts layered together instead of strung together.
It is in this context that several manufacturers began to investigate how they could get watches that could withstand such fields. IWC was the first to release a widely available watch against magnetic fields with its aptly named Ingénieur model. In order not to be left behind, Rolex has also released its own magnetic-resistant watch in the same period: the Rolex Milgauss (from the French "mille" and Gauss, so resistant to 1000 Gauss). James Stacey recently discussed a series of newly announced in-house documents from IWC, which will be released in 2013: the year of the engineer for IWC.
The Rolex Milgauss is, like all other Rolex sports arrangements, based on their famous and ubiquitous oyster-eternal cupboard. This is the same housing design used in the Submariner replica or in the Explorer models, but the Rolex Milgauss is made of polished 904L steel with a polished, smooth edge that gives it a unique character among the other members of the Rolex family of sports watches. On the back of the Rolex Milgauss, in contrast to the Submariner but like the Sea-Dweller, there are markings for the model, the brand and the Oyster housing.
In the early 1950s, Rolex launched a number of tool watches on the market. The Submariner for the divers, the Explorer for the adventurers, but also the scientists were not forgotten. People who work in a nuclear power plant or in laboratories have to deal with magnetic fields. There are ordinary watches, especially then, not against file. So Rolex came up with the solution, the Rolex Milgauss.
The watch was extensively tested by CERN, the world's most important laboratory. Up to 1000 gauss could bear it. Hence also the name Milgauss, Mille translated from Latin means 1000 and gauss the unit in which magnetism is measured. The watch declares its name, a true revolution at the time.
In the beginning, the second hand was made as a kind of lightning flash, years later it became a regular second hand with a red triangle. Corresponding to the red text. And that is what you see with us, really in mint condition. The vertically sanded silver dial is characteristic of this type of watch. Clearly readable and with a hacking system, which means that when the crown is pulled out the second's hand comes to a standstill, which was useful for accurate time measurement.
This is a replica watch with a great story while enjoying a cup of coffee we will gladly tell you more about it. You are welcome.
