On Baselworld 2014 we had a close look at the new Rolex Oyster Perpetual Milgauss.
Its green sapphire crystal marked a first in watchmaking when it was introduced on the Milgauss in 2007. Now this crystal is combined with an electric blue dial, an allusion to the emblematic lightning-bolt-shaped seconds hand and the watch’s technical purpose as a paramagnetic timepiece designed for engineers and scientists in the 1950s. Seen through the green sapphire crystal, the Z blue dial takes on a powerfully attractive magnetic hue.
Ever since its launch, the Milgauss has remained an avant-garde watch. It was created in 1956 for engineers and technicians who are exposed in their work to magnetic fields which disrupt the performance of mechanical watches. It was designed to resist strong interference of up to 1,000 gauss, hence its name – mille being French for thousand – while maintaining its performance and precision as an officially certified chronometer. A pioneer in magnetic resistance, it became known as the watch worn by scientists at the European Organization for Nuclear Research (CERN) in Geneva and gained a reputation as the ultimate watch of science and technological progress. Several innovations contribute to its resistance to magnetism. The first line of defence is a shield made of ferromagnetic alloys which surrounds the movement within the Oyster case, an invention patented by Rolex in 1954. The second line of defence involves two of the movement’s key components, the oscillator and the escapement, which are made of innovative paramagnetic materials developed by Rolex since the 2000s.
