The champagne colour of the Datejust 41’s dial is created through a technique called electroplating. The blank dial is immersed in a bath containing metal ions and conducting salts. An electric current is applied to the solution with the result that a thin layer of metal is deposited on the dial. The right temperature, immersion time, intensity of the electric current and metals used will determine the shades and tones of the dial, indicating the complexity of the technique. Always mastered in-house by Rolex.

The Rolex-developed Chronergy escapement is an optimized version of the Swiss lever escapement – the standard for mechanical watches. The escapement’s efficiency is enhanced by 15 per cent through innovative design and components made of nickel-phosphorus, which contribute to the calibre 3235’s power reserve of approximately 70 hours.

Rolex and CERN, the world’s pre-eminent particle physics laboratory, have had an association since the 1950s. In 1956, Rolex developed a watch to solve the problem of magnetic fields disrupting mechanical watches; the Milgauss was designed to withstand interference of up to 1,000 gauss. Rolex asked CERN’s scientists to test the watch and they were able to confirm its magnetic resistance thanks to a patented shield protecting the movement. Today, more than 60 years on, Rolex continues to partner CERN by supporting its scientific conferences and outreach events.

Finer than a human hair, the blue Parachrom hairspring is a key component of Calibre 3131, powering the Milgauss and contributing to its magnetic resistance. Manufacturing begins with the fusion of niobium and zirconium under vacuum at approximately 2,400° C. The resulting alloy rod is transformed during a series of operations to obtain a 3km-long wire with a diameter of 0.1mm. This wire is then flattened into an even finer ribbon, approximately 50 microns thick, before being cut into 20cm-long segments, each of which is coiled. The hairspring’s shape is fixed using a high-temperature thermal vacuum treatment. The hairspring is then given a Rolex overcoil, which ensures its regularity in any position.

Still ticking: created in 1956 for scientists to prevent the performance of their mechanical watches being disrupted by magnetic fields, the Milgauss has a shield protecting the movement from interference up to 1,000 gauss. Made in steel, this original model features a black dial, a rotatable bezel with a graduated insert in anodized aluminium and introduced the unmistakable seconds hand shaped like a lightning bolt.

The Milgauss takes its name from the French word for thousand “mille” and “gauss” – a unit to measure magnetic flux density.
