MILGAUSS
Oyster, 40 mm, steel
MILGAUSS
The Milgauss, introduced in 1956, was designed to meet the
demands of the scientific community and is capable of
withstanding magnetic fields of up to 1,000 gauss. It became
known notably as the watch worn by scientists at the European
Organization for Nuclear Research (CERN) in Geneva. The newgeneration Milgauss, introduced in 2007, features several
innovative components that enhance protection from magnetic
interference.

Style of the Milgauss
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.

Function of the Milgauss
AN EFFICIENT
SHIELDING SYSTEM
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.

Function of the Milgauss
PARAMAGNETIC
COMPONENTS
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.

Spirit of the Milgauss
HISTORY OF
THE MILGAUSS
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, created in 1956, the first watch of its
kind. Hence the name of the watch, mille being French for thousand.

Spirit of the Milgauss
THE LARGEST LABORATORY,
THE TINIEST PARTICLE
The European Organization for Nuclear Research (CERN), the world's preeminent particle physics laboratory, is at the cutting edge of scientific
research into the fundamental secrets of the universe.
It hosts the world's highest-energy particle accelerator. In the 1950s,
CERN was also one of the first scientific institutions to confirm that the
Milgauss watch could indeed resist magnetic fields of up to 1,000 gauss.

Features
904L
STAINLESS STEEL
Rolex uses 904L stainless steel for its steel watch
cases. 904L is mainly used in the high technology,
aerospace and chemical industries, where maximum
resistance to corrosion is essential. A superalloy, 904L
is extremely resistant and highly polishable. It maintains
its beauty even in the harshest environments. 904L
steel also provides a perfect complement to the
precious metals used by Rolex.

Features
THE PARACHROM
HAIRSPRING
In a mechanical watch, the oscillator is the guardian of
time. Conventional oscillator hairsprings are made of
ferromagnetic alloys, leaving them vulnerable to
magnetic fields, temperature variations and shocks that
interfere with their precision. After years of research,
Rolex created the blue Parachrom hairspring, which is
finer than a human hair.
Crafted from a highly stable paramagnetic alloy that
includes niobium and zirconium, it is insensitive to
magnetic fields and up to 10 times more resistant to
shocks. Historically, the unique blue color of the
hairspring has been a sign of prestige reserved for only
the most accurate timepieces.

Features
OYSTER BRACELET
The Oyster bracelet is a perfect alchemy of form and
function, aesthetics and technology. First introduced in
the late 1930s, this particularly robust and comfortable
metal bracelet with its broad, flat three-piece links
remains the most universal bracelet in the Oyster
collection.
11
Features
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. Its architecture, in common with all Oyster watch
movements, makes it singularly reliable.
13
Features
SUPERLATIVE
CHRONOMETER
The green seal accompanying every Rolex watch is a symbol of its status
as a Superlative Chronometer. This exclusive designation attests that it
has successfully undergone a series of specific final controls by Rolex in
its own laboratories according to its own criteria, in addition to the official
COSC certification of its movement. This unique testing of the
chronometric precision of the cased-up movement, as well as of the
watch’s waterproofness, self-winding and power reserve, pushes back
the boundaries of performance and makes Rolex the benchmark for
excellence in mechanical watches. The green seal is coupled with a
five‑year guarantee which applies to all Rolex models.
