Milgauss

Honouring science

Milgauss

The Rolex Milgauss was designed to meet the demands of the scientific community and is capable of withstanding magnetic fields of up to 1,000 gauss. The reliability and precision of an ordinary mechanical watch can be affected by a magnetic field of 50 to 100 gauss.

But many scientists are exposed to much higher magnetic fields during the course of their work. Rolex’s solution was the Milgauss — the first watch of its kind. Hence the name of the watch, mille being French for thousand. The Milgauss became known notably as the watch worn by scientists at the European Organization for Nuclear Research (CERN) in Geneva.

Design

A unique
identity

True to its scientific heritage

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.

The Milgauss features luminescent white or orange hour markers. A green sapphire crystal – with a twist of lime – produces light reflections while preserving optimal legibility. Yet another Rolex first.

Features

Resistance
to magnetic
interference

The first innovation at the heart of the Milgauss' resistance to magnetic interference is the shield inside the 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.

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.

Several key components in the movement of the new‐generation Milgauss are made of innovative paramagnetic materials, including the blue Parachrom hairspring. They were developed and are made in-house with advanced technology thanks to Rolex’s unique command of the whole watchmaking process.

1956, CERN

The largest laboratory, the tiniest particle

The Oyster Perpetual Milgauss is a pioneering anti-magnetic watch developed in 1956, worn by scientists and engineers, namely those from the European Organization for Nuclear Research (CERN).
CERN is the world's pre-eminent particle physics laboratory and home to the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator.

1956

The First Milgauss

The European Organization for Nuclear Research (CERN) is at the cutting edge of scientific research into the fundamental secrets of the universe. In the 1950s, CERN was one of the first scientific institutions to confirm that the Milgauss watch could indeed resist magnetic fields of up to 1,000 gauss.
