Pragnell - Rolex Milgauss

Milgauss

Rolex Milgauss

Launched in 1956, the Oyster Perpetual Milgauss was created for engineers and scientists who were exposed to magnetic fields in the course of their work. With the help of a magnetic shield developed by Rolex, the Milgauss was designed to resist strong interference of up to 1,000 gauss, hence the name of the watch (mille being French for thousand). The Milgauss soon became known as the watch worn by scientists at the European Organisation for Nuclear Research (CERN) in Geneva.

INSTANTLY RECOGNISABLE

The Milgauss has remained faithful to its scientific heritage and unique identity as it has evolved. With its clean lines and evocative orange seconds hand, shaped like a lightning bolt to echo the original model, the Milgauss is recognisable at a glance.

  • Features

AN EFFICIENT SHIELDING SYSTEM

The first innovation at the heart of the Milgauss' resistance to magnetic interference is the shield inside its Oyster case. Made of ferromagnetic alloys selected by Rolex, it surrounds and protects the movement. The symbol for magnetic flux density – the capital letter 'B' with an arrow – is engraved in this magnetic shield, but only Rolex-certified watchmakers will ever see it.

3131 MOVEMENT

The Milgauss is equipped with calibre 3131, a self-winding mechanical movement entirely developed and manufactured by Rolex. It incorporates state-of-the-art technologies patented by the brand that ensure exceptional resistance to magnetic fields. Like all Rolex Perpetual movements, the 3131 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests.
