GMT-MASTER II
OYSTER PERPETUAL

WEARING THE WATCH
FOR THE FIRST TIME
Before being worn for the first time, or if it has
stopped, a Rolex watch must be wound manually
in order to function correctly and precisely.
To wind the watch manually, unscrew the winding
crown completely, then turn it several times
clockwise. (Turning in the other direction has
no effect.) A minimum of 25 turns is required for
adequate partial winding. The watch will then
be wound automatically as long as it is worn on
the wrist. Carefully screw the crown back down
against the case to ensure waterproofness.

The green seal accompanying your
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 in addition to the official
COSC certification of its movement.
This unique testing of its chronometric
precision, waterproofness, self-winding
and reliability pushes back the
boundaries of performance and makes
Rolex the benchmark for excellence
in mechanical watches. For further

THE INTERCONTINENTAL
PILOT’S WATCH
Precise, reliable and functional, the
Oyster Perpetual GMT-Master II was
designed to allow airline pilots to read
the time in three different time zones,
two of them simultaneously. It features
a 24-hour hand and a bidirectional
rotatable 24-hour graduated bezel.
Its 40 mm case, waterproof to a depth
of 100 metres (330 feet) is a paragon
of robustness. Its dial offers exceptional
legibility thanks to the Chromalight
hour markers and hands filled with
a luminescent material emitting a long-
lasting blue glow. Its Triplock winding
crown, with a triple waterproofness
system, is protected by a crown guard
that is an integral part of the middle
case. The sapphire crystal, with a
Cyclops lens, is virtually scratchproof.
The Oyster Perpetual GMT-Master II is
equipped with a self-winding mechanical
movement entirely manufactured
by Rolex.
The Oyster Perpetual GMT-Master II
features an Oyster bracelet with an
Oysterlock safety clasp and the Easylink
comfort extension link.

TRIPLE TIME ZONE AND
24 -HOUR DISPLAY
The Oyster Perpetual GMT-Master II
allows travellers to adjust the watch to
different time zones during a journey,
while benefiting from a constant, clear
display of the reference time.
During a journey, the reference time is
indicated by the triangle-tipped 24-hour
hand. It is read against the graduations on
the bezel placed in the neutral position.
Local time is indicated by the conventional
hour, minute and seconds hands. It can
be adjusted quickly and easily by jumps
of the hour hand without affecting the

7
functioning of the watch. The date change
is linked to the local time. Thus, the date
window always displays the current date
in the wearer’s local time zone.
By using the rotatable bezel, a third time
zone can also be displayed.

COMPLETE SETTING OF THE WATCH
IS CARRIED OUT BY FOLLOWING THE
TWO STEPS IN THE ORDER GIVEN:
1. Setting the reference time
(crown in position 3):
To set the reference time, follow the
steps in the order given:
– Unscrew the crown and then pull it
out to the second notch. The seconds
hand is stopped, allowing you to set
the time to the precise second.
– Put the bezel in the neutral position
(triangle on the bezel aligned with the
12 o’clock marker on the dial).
– Set the reference time using the
24-hour hand (against the graduations
on the bezel) and the minute hand
(against the graduations on the dial)
by turning the crown in either direction.
Setting the reference time also moves
the conventional hour hand (local time).
For this reason, the reference time must
be set before setting the local time.

THIRD TIME ZONE DISPLAY
(setting via the bezel only):
A third time zone can be displayed by
using the rotatable bezel and the 24-hour
hand. It is based on the reference time.
To display the third time zone, turn the
bezel clockwise (for a negative time
difference) or counterclockwise (for a
positive time difference) according to the
time difference between the reference
time (24-hour hand) and the time in the
desired time zone.
Example:
To show Tokyo time (
+ 8 hr compared
to Geneva reference time), turn the bezel
8 notches counterclockwise.
The 24-hour hand read against the bezel
indicates the time in the third time zone.
The minutes are shown on the dial by
the minute hand.
To return to the reference time display,
turn the bezel in either direction to place
the triangle on the bezel opposite the
12 o’clock marker on the dial.

Unscrew and then pull out
*Reference time, Geneva, 10.10 a.m.
Local time, New York, 4.10 a.m.
Time in the third time zone, Tokyo, 6.10 p.m.

back down against the case to guarantee
the waterproofness. The crown should never
be unscrewed under water.
