Description

First launched in 1956 for scientists and engineers, the timepiece derived its nomenclature from the words “mille” and “gauss” (the latter being a unit of magnetic measurement) – literally translating to 1,000 Gauss.

The Milgauss follows the concept of using a Faraday cage – made of ferromagnetic alloys – to protect the movement. It consists of two shield, one screwed to the movement and the other to the cage, to prevent the movement’s components from getting magnetized. Its efficacy was proven when the timepiece was sent for testing to The European Organization for Nuclear Research (CERN).

The Rolex Milgauss is powered by the brand’s in-house Caliber 3131. This is a self-winding movement, with a power reserve of around 48 hours. Aside from the Parachrom hairspring (which is anti-magnetic), the watch is also fitted with an additional magnetic shield to protect the movement. Finally, it is Superlative Chronometer certified, and it promises a deviation of not more than 2 seconds a day.
