ROLEX Oyster Perpetual Cosmograph Daytona Watch Instruction Manual

ROLEX Oyster Perpetual Cosmograph Daytona Watch

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 information, please visit rolex.com.

OYSTER PERPETUAL COSMOGRAPH DAYTONA

The Oyster Perpetual Cosmograph Daytona is the benchmark for those with a passion for driving and speed. Of legendary relia bility, this model features a center chronograph seconds hand, 30-minute and 12-hour counters and
a tachymetric bezel, making it the instrument of choice for measuring elapsed time and calculating average speeds.
The dial offers exceptional legibility thanks to its Chromalight display elements filled with a high-performance luminescent material.
Its 40 mm Oyster case, guaranteed waterproof to a depth of 100 meters
(330 feet), is a paragon of robustness and reliability. Its Triplock winding crown, with a triple water proofness system, is protected by a crown guard crafted as an integral part of the middle case. Both the winding crown and the chronograph pushers screw down against the case. Its sapphire crystal is virtually scratchproof.
The Oyster Perpetual Cosmograph Daytona is equipped with a self-winding mechanical movement entirely manufactured by Rolex.

SETTING THE WATCH

Screwed-down position (crown in position 0, pushers screwed down) The crown and pushers are completely screwed down against the case. When the crown and pushers are in this position, the Oyster Perpetual Cosmograph Daytona is guaranteed waterproof to a depth of 100 meters
(330 feet).

Manual winding (crown in 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.

Setting the time (crown in position 2) The crown is unscrewed and pulled out to the first notch. The small 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.

Initial winding and setting

• Wind the watch manually (position 1).
• Set the time (position 2).

MEASURING ELAPSED TIME

To measure elapsed time, follow the steps in the order given:

• Completely unscrew the pushers by turning them counterclockwise.
• Ensure that the chronograph seconds hand is stopped. If necessary, stop it by pressing the upper pusher.
• Press the lower pusher to reset the chronograph seconds hand and counters to zero.
• Press the upper pusher to start timing.
•  Press the upper pusher again to stop timing.
•  Read the elapsed time. The center seconds hand displays the elapsed seconds, for a precise reading. The two counters at 3 o’clock and 9 o’clock on the dial indicate respectively the elapsed minutes and hours.
•  Screw the pushers back down by turning them clockwise.
• Elapsed time in this illustration is 8 h 06 min 04 s

CALCULATING AVERAGE SPEED PER HOUR

The Oyster Perpetual Cosmograph Daytona can be used to calculate average speeds per hour over a given distance (1 km, 1 mile, etc.).
To calculate average speed per hour, follow the steps in the order given:

•  Completely unscrew the pushers by turning them counterclockwise.
• Ensure that the chronograph seconds hand is stopped. If necessary, stop it by pressing the upper pusher.
• Press the lower pusher to reset the chronograph seconds hand and counters to zero.
•  At the starting point of the distance  to be covered, press the upper pusher to start timing.
• When the distance has been covered, press the upper pusher to stop timing.
• The chronograph seconds hand indicates the average speed per hour on the graduated bezel (chosen unit of distance/h).
• Screw the pushers back down by turning them clockwise.
• Over a distance of 1 km, the average speed in this illustration is 160 km/h

EASYLINK COMFORT EXTENSION LINK

To ensure optimal comfort when wearing your watch in any circumstances, Rolex created the Easylink comfort extension link, which is available on some models. Its exclusive design, which was patented, allows the length of the bracelet to be adjusted by approximately 5 mm, without the use of tools.

Thanks to Rolex expertise, your watch will require very little day-to-day care.
You can help preserve its luster by cleaning it occasionally with a microfiber 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 Jeweler or Service Center for professional servicing. When your watch is serviced by a Rolex watchmaker, the watch is completely dismantled and all of its components are cleaned. Each individual component is closely examined and those that
no longer meet Rolex’s functional and aesthetic specifications are replaced with genuine Rolex parts.
The movement is carefully lubricated then tested to guarantee its timing accuracy; the case and the metal bracelet are meticulously refinished to restore  their luster. Your Rolex then undergoes a series of rigorous technical tests and checks to guarantee its waterproofness, power reserve and precision.
After a complete Rolex service, your watch is covered by a service warranty.
