gmt-master ii
40 mm in gold
The GMT-Master, introduced in 1955, was developed to
meet the needs of international pilots. The GMT-Master II,
unveiled in 2005, has proved to be even more invaluable
to those whose professions involve long-distance travel.
Featuring a rotatable 24-hour graduated bezel and a
separate 24-hour hand, it allows those who travel the world
to read three different time zones. Two simultaneously.
Introduction

Style of the GMT-Master II
keeping pace with
changing times
Although the GMT-Master II was designed essentially for
professional use, its combination of peerless functionality
and rugged good looks has attracted a wider travelling
public. As well as appreciating its ability to display different
time zones, these travellers admire the robustness and
versatile appearance that make the GMT-Master eminently
suitable for globetrotting and, indeed, for any occasion.

Function of the GMT-Master II
24-hour display
and independent
hour hand
In addition to conventional hour, minute and seconds
hands, the GMT-Master II features an arrow-tipped hand,
which circles the dial once every 24 hours, as well as
a bidirectional rotatable 24-hour graduated bezel. The
distinctively coloured 24-hour hand displays the "home"
reference time in a first time zone which can be read on
the graduations on the bezel. The traveller’s local time is
easily set by "jumping" from hour to hour, thanks to an
ingenious mechanism operated via the winding crown:
the hour hand can be adjusted forwards or backwards
independently of the minute and seconds hands. This
allows travellers to adapt to their new time zone without
affecting the precision of their timekeeping.

Function of the GMT-Master II
24-hour
rotatable bezel
The bezel is the traveller’s faithful companion through
time. Rolex developed a new rotation system that allows
the bezel to be turned in either direction and locate with a
positive click in each of the 24 hour positions, without any
possibility of an intermediate stop or accidental changes.
The powerful spring mechanism allows crisp, precise
movements, and works reliably over time. Apart from
securely indicating home or reference time, the bezel can
also be rotated to read a third time zone using the 24-hour
hand.

Function of the GMT-Master II
second time zone
The GMT-Master II evokes intercontinental travel across time zones. Greenwich
Mean Time (GMT) marks mean solar time at the Royal Observatory in Greenwich,
London – the location of the original meridian used for calculating longitude and
determining different time zones around the world. A second time zone can be
set swiftly and read at a glance on a GMT-Master II.

Spirit of the GMT-Master II
the product
of the jet age
As intercontinental travel developed in the 1950s with
the advent of the jet age, airliners began to fly swiftly
across several successive time zones, obliging pilots to
keep an eye on the time in various places in the world
simultaneously (such as the airport of departure and arrival,
or local time and GMT reference time). The GMT-Master
was developed to meet their needs, at the height of the
golden age of air travel. It became the official watch of
several intercontinental airlines, notably the famous Pan
American World Airways, better known as Pan Am.

Spirit of the GMT-Master II
supersonic luxury
When Concorde performed its final test flights in the 1960s,
Rolex proudly announced that both the British and
French test pilots (Brian Trubshaw and André Turcat) wore
GMT-Masters. In an era of supersonic flight, the GMTMaster had become invaluable.

Features
cerachrom bezel
Manufactured by Rolex from an extremely hard ceramic
material since 2005, the exclusive Cerachrom bezel
insert and monobloc bezel have excellent anti-corrosion
properties and keep their vibrant colours over time.
They are virtually scratchproof, and are unaffected by
exposure to sunlight as well as to chlorinated or sea
water. To inscribe the numerals and graduations on such
a hard material, Rolex developed a unique process which
culminates in their being coated with a thin layer of yellow
gold or platinum. It takes 40 hours to produce each
Cerachrom bezel. At Rolex, no measure is too extreme
in the pursuit of beauty and function.

Features
triplock
winding crown
The Triplock winding crown is a patented triple
waterproofness system designed especially for divers’
watches. Developed by Rolex, it resists water pressure
to depths of 300 metres (1,000 feet) on the Submariner
models and some other Professional models, and
3,900 metres (12,800 feet) on the Rolex Deepsea.
First introduced in 1970, the Triplock system consists
of 10 different elements crafted from the most reliable
materials. The winding crown screws down against the
Oyster case as tightly and hermetically as a submarine’s
hatch.

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.
Features
12
Features
easylink
An increase in temperature, altitude or physical activity may cause your wrists
to expand and can even make wearing a watch uncomfortable. This is why
Rolex invented and patented Easylink, an extension system that lets the wearer
increase the bracelet length by about 5 mm to regain maximum comfort.
Perfectly integrated into the watch’s design and hidden beneath the clasp,
the Easylink system’s opening and closing mechanism is tested thousands
of times in the most extreme conditions to guarantee reliability.
Features

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 colour of the hairspring
has been a sign of prestige reserved for only the
most accurate timepieces.
Features

Features
3186 movement
The GMT-Master II is equipped with calibre 3186, a selfwinding mechanical movement entirely developed and
manufactured by Rolex. In addition to the conventional
hour, minute and seconds hands, it features a 24-hour hand
to display a second time zone. Like all Rolex Perpetual
movements, the 3186 is a certified Swiss chronometer,
a designation reserved for high-precision watches that
have successfully passed the Swiss Official Chronometer
Testing Institute (COSC) tests. The 3186 is equipped with a
Parachrom hairspring, offering greater resistance to shocks
and to temperature variations. Its architecture, in common
with all Oyster watch movements, makes it singularly
reliable.
Features

Features
certified swiss
chronometer
The four simple words Superlative Chronometer
Officially Certified on a Rolex watch dial mean that
the very movement inside the timepiece has endured
15 days and nights of testing by COSC (Contrôle
Officiel Suisse des Chronomètres – Swiss Official
Chronometer Testing Institute), an independent notfor-profit association.
To receive COSC certification as a Swiss
chronometer, a watch must demonstrate extreme
precision in a variety of positions and temperatures.
Rolex is unique in the industry: this is the standard
level of quality required of every Rolex wristwatch
movement.
