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 manuallyin 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 foradequate partial winding. The watch will thenbe wound automatically as long as it is worn onthe wrist. Carefully screw the crown back down
against the case to ensure waterproofness.

The green seal accompanying yourRolex watch is a symbol of its status
as a Superlative Chronometer. This
exclusive designation attests that it
has successfully undergone a series ofspecific final controls by Rolex in its ownlaboratories in addition to the official
COSC certification of its movement.
This unique testing of its chronometricprecision, waterproofness, self-winding
and reliability pushes back theboundaries of performance and makes
Rolex a benchmark for excellencein mechanical watches. For further

5OYSTER PERPETUALDEEPSEA CHALLENGEThe Oyster Perpetual Deepsea Challenge,
guaranteed waterproof to a depthof 11,000 metres (36,090 feet), is createdfrom RLX titanium, a material that isvery robust and lightweight. Its patented
Ringlock System architecture allows it
to resist the pressure at these extreme
depths. Its dial offers exceptional
legibility thanks to the Chromalight hourmarkers and hands. Equipped withthe helium escape valve, its 50 mm
case is a paragon of robustness. The
Triplock winding crown, with a triple
waterproofness system, is protected bya crown guard that is an integral partof the middle case. The slightly domed
sapphire crystal is 9.5 mm thick, virtuallyscratchproof and benefits from an antireflective coating.
The Oyster Perpetual Deepsea Challenge
is equipped with a self-winding
mechanical movement entirely
manufactured by Rolex.
The Oyster Perpetual Deepsea Challenge
features an Oyster bracelet with an
Oysterlock safety clasp, the Rolex
Glidelock extension system and a Fliplockextension link.

THE HEART OF THE
DEEPSEA CHALLENGE MODELUSINGYOUR WATCHROLEXSERVICEHELIUM ESCAPE VALVE
Professional saturation divers spendlong periods of time in a hyperbaricchamber, where the gas mixture theybreathe contains a significant proportionof helium. The molecules are so smallthat they penetrate the watch case.
During the decompression phase thatenables divers to gradually eliminate thegas mixture absorbed by their bodies
and returns them to normal atmosphericpressure, the helium cannot always
escape from the watch case sufficiently

quickly. This phenomenon can resultin a build-up of pressure inside thetimepiece, leading to damage or evenseparating the crystal from the case.
To allow the gas to be released withoutcompromising the waterproofnessof the watch, the Oyster PerpetualDeepsea Challenge is equipped with thehelium escape valve. This unidirectionalvalve activates automatically when thepressure inside the case is too high.

Manual winding (position 1)
The crown is unscrewed. To wind thewatch manually, turn the crownclockwise; turning in the other direction
has no effect. When setting the watch

for the first time or after the watch
has stopped, complete a minimumof 25 turns for partial winding.
Setting the time (position 2)
The crown is unscrewed and pulled out
to the first notch. The seconds handis stopped, allowing you to set the timeto the precise second. To set the hourand minute, turn the crown in either
direction.

13UNIDIRECTIONAL
ROTATABLE BEZELThe Oyster Perpetual Deepsea Challengeallows divers to safely monitor theirdive time thanks to the unidirectionalrotatable bezel fitted with a 60-minutegraduated Cerachrom insert made ofparticularly durable ceramic.
Before the dive
Before beginning your descent, turnthe bezel until the triangle on thegraduation is opposite the minute hand.
It indicates the beginning of the diveand is visible in the dark thanks to aphosphorescent capsule.

During the dive
The duration of the dive is indicatedon the graduation on the Cerachrom insert
by the minute hand.
For safety reasons, the bezel turns only
counterclockwise. Accidental rotationof the bezel can therefore only shorten
the dive time.

On the Oyster bracelet, the Rolex
Glidelock extension system enables
the bracelet length to be adjusted

AFTER-SALESSERVICE
Rolex watch servicing ensures thatyour timepiece will continue toperform optimally and meet Rolex’s
stringent requirements in terms ofprecision, 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 wearof components. To guarantee continued
accuracy and waterproofness, Rolex
recommends that you periodically return
your watch to an Official Rolex Retailer orService Centre for professional servicing,which will always be carried out by a
Rolex-approved watchmaker.
During a complete service, the watch isdismantled and all of its components– the case, bracelet and movement – areclosely examined.
The movement is entirely disassembled
and all the parts are carefully inspected.
Those that no longer meet Rolex
requirements are systematically replacedby new components. The movement
is lubricated on reassembly. The case

21and bracelet are re-polished or satinfinished according to their original finish,
restoring their shine and lustre whileremoving any marks or scratches.
At the end of the process, your Rolex
watch undergoes a series of tests toverify its functions, waterproofness andpower reserve, as well as the precisionof its movement.
After a complete Rolex service, yourwatch is covered by a service guarantee.
