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 a benchmark for excellence
in mechanical watches. For further

The Oyster Perpetual Explorer II is the
watch of choice for explorers. Thanks
to a 24-hour display by means of an
additional hand and a graduated fixed
bezel, the watch allows the wearer
to distinguish daytime from night-time
hours or to read the time in a second
time zone. Its 42 mm case, waterproof
to a depth of 100 metres (330feet), is a
paragon of robustness. The easy-to-read
dial features Chromalight hour
markers and hands, which are filled
with aluminescent material emitting
a long-lasting blue glow when in
darkness. Its winding crown is protected

by a crown guard that is an integral
part of the middle case. The sapphire
crystal, with a Cyclops lens at 3 o’clock,
is virtually scratchproof.

The Oyster Perpetual Explorer II is
equipped with a self-winding mechanical
movement entirely manufactured
byRolex.

The Oyster Perpetual Explorer II features
an Oyster bracelet with an Oysterlock
safety clasp and the Easylink comfort
extension link.

DISTINCTION BETWEEN DAY AND NIGHT
OR SECOND TIME ZONE

The Explorer II’s additional, 24-hour
hand circles the dial once every
24 hours and is used in combination
with the graduated fixed bezel.
Orange and arrow-shaped, it enables
the wearer to either see the time
in 24-hour format – which is particularly
useful in areas where it is difficult
to distinguish between day and
night, such as underground or in
polar regions – or to read the time
in a second time zone.

When the Explorer II shows the time in
24-hour format, the 24-hour hand points
to the graduated bezel, allowing the
wearer to clearly distinguish daytime
from night-time, while the conventional
hands indicate the hours and minutes.

If the Explorer II displays the time
in two time zones simultaneously,
the reference time is indicated on the
graduated bezel by the 24-hour hand.
Local time is shown by the conventional
hour and minute hands.

In both cases, the minutes are always
displayed by the conventional minute
hand.

Screwed-down position (position 0)

The crown is completely screwed down
against the case. When the crown
is in this position, the Oyster Perpetual
Explorer II is guaranteed waterproof
to a depth of 100 metres (330 feet).

Manual winding (position 1)

The crown is unscrewed. To wind
the watch manually, turn the crown
clockwise; turning in the other direction
has no effect. When setting the watch
for the first time or after the watch
has stopped, complete a minimum
of25turns for partial winding.

Unscrew

After every use, carefully screw the crown
back down against the case to guarantee the
waterproofness. Return the crown to position1
and apply light pressure on it while screwing
it down clockwise against the case. The crown
should never be unscrewed underwater.

TIME WITH DISTINCTION
BETWEEN DAY AND NIGHT

1. Setting the 24-hour hand
(crown in position 3)

To set the 24-hour hand, 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.

– Set the 24-hour hand (against the

24-hour graduated bezel) and
the minute hand (against the dial)
by turning the crown in either direction.

Setting the 24-hour hand also moves
the conventional hour hand. This hour
hand must, therefore, be set separately
(see step 2).

Go to step 2

* Time in 24-hour format (distinction

between day and night): 22:10

Unscrew and then pull out

After every use, carefully screw the crown
back down against the case to guarantee the
waterproofness. Return the crown to position1
and apply light pressure on it while screwing
it down clockwise against the case. The crown
should never be unscrewed underwater.

2. Setting the date and the hour hand
(crown in position 2)

To set the date and the hour hand, follow
the steps in the order given:
– Pull out the crown to the first notch.
– Set the date by turning the crown in

either direction. The hour hand moves
in increments of one hour. The date
changes when the hour hand passes
midnight, in either direction, after two
full turns around the dial.

– Set the hour hand by turning the

crown in either direction. The hour
hand moves in increments of one hour.
Be aware of the difference between
noon and midnight (the date changes
as the hour hand passes midnight).

– Push in and then screw down the crown.

* Time via conventional hands: 10.10 am

Time in 24-hour format (distinction

between day and night): 22:10

DUAL TIME ZONE FUNCTION

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.

– 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
(see step 2).

Go to step 2

* Reference time (Geneva) in 24-hour format: 10:10

Unscrew and then pull out

After every use, carefully screw the crown
back down against the case to guarantee the
waterproofness. Return the crown to position1

EASYLINK COMFORT
EXTENSION LINK

To ensure optimal comfort when wearing
your watch, Rolex created the Easylink
comfort extension link. Its exclusive
design comprises a link that is pulled
out or folded back on itself to adjust the
length of the bracelet by approximately
5 mm, without the need for tools.

Thanks to Rolex expertise, your watch
will require very little day-to-day care.

You can help preserve its lustre by
cleaning it occasionally with a microfibre
cloth. You can also wash the case and
bracelet from time to time using soapy
water and a soft brush. After wearing
your watch in the sea, it is important to
rinse it with fresh water to remove any
salt and sand deposits.

Before cleaning your watch, always
ensure that the crown is screwed down
properly against the case to guarantee
waterproofness.

Rolex watch servicing ensures that
your timepiece will continue to
perform optimally and meet Rolex’s
stringent requirements in terms of
precision, reliability and waterproofness
throughout its life.

The timekeeping accuracy of your watch
is largely dependent on high-performance
lubricants specially developed by Rolex
to minimize friction and prevent wear
of components. To guarantee continued
accuracy and waterproofness, Rolex
recommends that you periodically return
your watch to an Official Rolex Retailer or

Service Centre for professional servicing,
which will always be carried out by a
Rolex-approved watchmaker.

During a complete service, the watch is
dismantled and all of its components
– the case, bracelet and movement – are
closely examined.

The movement is entirely disassembled
and all the parts are carefully inspected.
Those that no longer meet Rolex
requirements are systematically replaced
by new components. The movement
is lubricated on reassembly. The case

and bracelet are re-polished or satin­finished according to their original finish,
restoring their shine and lustre while
removing any marks or scratches.

At the end of the process, your Rolex
watch undergoes a series of tests to
verify its functions, waterproofness and
power reserve, as well as the precision
of its movement.

After a complete Rolex service, your
watch is covered by a service guarantee.
