Rolex Oyster Perpetual Cosmograph Daytona

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 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 the boundaries of performance and makes Rolex a benchmark for excellence in mechanical watches.

Overview of the Cosmograph Daytona Model

The Oyster Perpetual Cosmograph Daytona features a 40 mm Oyster case, guaranteed waterproof to a depth of 100 meters (330 feet). It is a paragon of robustness and reliability, with a Triplock winding crown and a triple waterproofness system, 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 watch is equipped with a self-winding mechanical movement entirely manufactured by Rolex.

Using Your Watch

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 in this position, the watch is guaranteed waterproof to 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 it 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.

After every use, carefully screw the crown back down against the case to guarantee 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.

Measuring Elapsed Time

To measure elapsed time, follow these steps:

• 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. The two counters at 3 o'clock and 9 o'clock indicate the elapsed minutes and hours, respectively.
• Screw the pushers back down by turning them clockwise.

* Elapsed time in the illustration is 8h 06 min 04s

Calculating Average Speed Per Hour

The Oyster Perpetual Cosmograph Daytona can be used to calculate average speeds per hour over a given distance (e.g., 1 km, 1 mile).

To calculate average speed per hour, follow these steps:

• 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

Caring for Your Rolex

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, it 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.
