OYSTER PERPETUAL COSMOGRAPH DAYTONA ROLEX
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.

ROLEX OYSTER PERPETUAL SUPERLATIVE. CHRONOMETER OFFICIALLY CERTIFIED COSMOGRAPH
The Oyster Perpetual Cosmograph Daytona is the benchmark for those with a passion for driving and speed. Of legendary reliability, this model features a centre chronograph seconds hand, 30-minute and 12-hour counters, and a tachymetric bezel. It is the instrument of choice for measuring elapsed time or calculating average speeds. The dial offers exceptional legibility thanks to its Chromalight display elements filled with a high-performance luminescent material. The 40 mm Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reliability. Its Triplock winding crown, with a triple waterproofness 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. The sapphire crystal is virtually scratchproof and benefits from an anti-reflective coating. The Oyster Perpetual Cosmograph Daytona is equipped with a self-winding mechanical movement entirely manufactured by Rolex. S

Thanks to Rolex expertise, your watch will require very little day-to-day care. 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.
Rolex after-sales servicing ensures that your timepiece will continue to perform optimally in terms of precision, reliability and waterproofness, and also retain its particular lustre. The proper functioning and timekeeping accuracy of your Rolex watch movement is dependent on high-performance lubricants specially developed by the brand. Over time, the properties of all lubricants will degrade, which can affect a movement's precision. Additionally, to verify the waterproofness of your watch, it is important to carry out stringent technical checks. Rolex therefore recommends that you periodically return your watch to one of its Official Rolex Retailers or Service Centres for complete servicing, which is always performed 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.
