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. Thisexclusive 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 PERPETUAL SEA-DWELLER
The Oyster Perpetual Sea-Dweller,
guaranteed waterproof to a depth of
1,220 metres (4,000 feet), was designedto accompany the pioneers of deep-sea
diving. Its helium escape valve andunidirectional rotatable bezel make ita true professional diving instrument.
Its dial offers exceptional legibility
thanks to the Chromalight hour markers
and hands coated with a luminescentmaterial emitting a long-lasting blue
glow when in darkness. The 43 mm
case is a paragon of robustness.
The Triplock winding crown, with a triple
waterproofness system, is protected by acrown guard that is an integral partof the middle case. The sapphire crystal,with a Cyclops lens at 3 o’clock, isvirtually scratchproof and benefits froman anti-reflective coating.
The Oyster Perpetual Sea-Dweller isequipped with a self-winding mechanicalmovement entirely manufacturedby Rolex.
The Oyster Perpetual Sea-Dweller features
an Oyster bracelet with an Oysterlock
safety clasp and the Rolex Glidelock
extension system.

6HELIUM ESCAPE VALVE
Professional saturation divers spendlong periods of time in a hyperbaric
chamber, 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.

7

To allow the gas to be released withoutcompromising the waterproofness of thewatch, the Oyster Perpetual Sea-Dweller
is equipped with the helium escapevalve. This unidirectional valve activates
automatically when the pressure inside
the case is too high.

15UNIDIRECTIONAL
ROTATABLE BEZELThe Oyster Perpetual Sea-Dweller allows
divers to safely monitor their dive time
thanks to the unidirectional rotatablebezel fitted with a 60-minute graduatedCerachrom insert made of particularly
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.

restoring their shine and lustre whileremoving any marks or scratches.
