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.

THE HEART OF THE SEA-DWELLER MODELS

OYSTER PERPETUAL ROLEX DEEPSEA

The Oyster Perpetual Rolex Deepsea illustrates Rolex’s expertise in mastering waterproofness. Guaranteed waterproof to a depth of 3,900 metres (12,800 feet), it benefits from the Ringlock system, a Rolex-developed, patented case architecture that enables it to resist the pressure at these depths. Its helium escape valve and unidirectional rotatable bezel make it a true professional diving instrument. Its dial offers exceptional legibility thanks to the Chromalight hour markers and hands filled with a luminescent material emitting a long-lasting blue glow when in darkness. The 44 mm case is a paragon of robustness.

The 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 is virtually scratchproof and benefits from an anti-reflective coating.

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

The Oyster Perpetual Rolex Deepsea features an Oyster bracelet with an Oysterlock safety clasp and the Rolex Glidelock fine-adjustment system.

HELIUM ESCAPE VALVE

Professional saturation divers spend long periods of time in a hyperbaric chamber, where the gas mixture they breathe contains a significant proportion of helium. The molecules are so small that they penetrate the watch case.

During the decompression phase that enables divers to gradually eliminate the gas mixture absorbed by their bodies and returns them to normal atmospheric pressure, the helium cannot always escape from the watch case sufficiently quickly. This phenomenon can result
in a build-up of pressure inside the timepiece, leading to damage or even separating the crystal from the case.

To allow the gas to be released without compromising the waterproofness of the watch, the Oyster Perpetual Sea-Dweller and the Oyster Perpetual Rolex Deepsea are equipped with the helium escape valve. This unidirectional valve activates automatically when the pressure inside the case is too high.

Description

The Rolex Oyster Perpetual Sea-Dweller is crafted with precision and durability in mind. The watch features a distinctive dial with large hour markers and hands, ensuring clear readability even in low-light conditions. The case is built from high-quality materials such as 904L stainless steel or 18k gold, providing exceptional strength and corrosion resistance. The watch’s unidirectional rotating bezel allows divers to monitor their dive time accurately. Additionally, the helium-escaping valve ensures safe decompression during ascents from deep dives.

SETTING THE WATCH

Screwed-down position (position 0)
The crown is completely screwed down against the case. When the crown is in this position, the Oyster Perpetual Sea-Dweller and the Oyster Perpetual Rolex Deepsea are guaranteed waterproof to a depth of 1,220 and 3,900 metres (4,000 and 12,800 feet), respectively.

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.

Initial winding and setting

Wind the watch manually (position 1 ).
Note the date change at midnight, then set the time (position 3 ).
Set the date (position 2 ).

setting_the_time_(position_3)-rolex_oyster_perpetual_sea-dweller_watch.png

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.

Setting the date (position 2)
The crown is unscrewed and pulled out to the first notch. To set the date, turn the crown clockwise. (Turning in the other direction has no effect.) During this operation, the watch continues to function.

Setting the time (position 3)
The crown is unscrewed and pulled out to the second notch. The seconds hand is stopped, allowing you to set the time to the precise second. To set the hour and minute, turn the crown in either direction. To avoid confusion between am and pm hours, move the hour hand to 12 o’clock. If the date changes, it is midnight.

Setup Guide

To operate the Rolex Oyster Perpetual Sea-Dweller, follow these steps:

Setting the Time:** Pull the crown out to the first position to set the date and the second position to set the time.
Using the Bezel:** Rotate the unidirectional bezel counterclockwise to set the desired dive time.
Activating the Helium-Escaping Valve:** This valve operates automatically; no manual intervention is required.
Winding the Watch:** If the watch has stopped, wind it by rotating the crown while it is in the first position.

UNIDIRECTIONAL ROTATABLE BEZEL

The Oyster Perpetual Sea-Dweller
and the Oyster Perpetual Rolex Deepsea allow divers to safely monitor their dive time thanks to the unidirectional rotatable bezel fitted with a 60-minute graduated Cerachrom insert made of particularly durable ceramic.
Before the dive
Before beginning your descent, turn the bezel until the triangle on the graduation is opposite the minute hand. It indicates the beginning of the dive and is visible in the dark thanks to a phosphorescent capsule.

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

ROLEX GLIDELOCK FINE-ADJUSTMENT SYSTEM

On the Oyster bracelet, the Rolex Glidelock fine-adjustment system enables the bracelet length to be adjusted in approximately 2 mm increments up to around 20 mm, allowing the watch to be worn over a diving suit.

ROLEX SERVICE

CARING FOR YOUR ROLEX

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.

AFTER-SALES SERVICE
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 satin-finished 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.
