OYSTER PERPETUAL SKY-DWELLER
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 Oyster Perpetual Sky-Dweller provides, in an unprecedented way, the information frequent travellers need to easily keep track of time: a dual time zone and an innovative annual calendar named Saros. The watch is set using the Ring Command system, a revolutionary mechanism of interaction between the rotatable bezel, the winding crown and the movement. The 42 mm Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and elegance. The sapphire crystal, featuring a Cyclops lens at 3 o'clock, is virtually scratchproof and benefits from an anti-reflective coating. The Oyster Perpetual Sky-Dweller is equipped with a self-winding mechanical movement entirely manufactured by Rolex. The Oyster Perpetual Sky-Dweller features an Oyster or Jubilee bracelet with an Easylink comfort extension link or an Oysterflex bracelet with the Rolex Glidelock extension system. All three bracelets are equipped with an Oysterclasp. 5
The Oyster Perpetual Sky-Dweller allows the traveller to read the time in two different time zones simultaneously. The reference time can be read in 24-hour format via a rotating off-centre disc. A fixed red triangle on the dial points to the time. 6 Local time is indicated by the conventional centre hour, minute and seconds hands. It can be set quickly and easily by jumps of the hour hand. Setting the hour hand does not affect the minute or seconds hands or the reference time. The instantaneous date change is linked to local time. Thus, the date window always displays the current date in the wearer's local time zone.
The Oyster Perpetual Sky-Dweller has an innovative annual calendar thanks to an ingenious patented mechanism, named Saros, whose unique design was inspired directly by the astronomical phenomenon of the same name. This annual calendar, which automatically differentiates between 30-day and 31-day months, displays the correct date throughout the year. It requires only one adjustment a year – on 1 March, February having only 28 or 29 days. The current month is indicated in red in one of the 12 windows around the circumference of the dial: January at 1 o'clock, February at 2 o'clock, and so on. 8

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. The network of Official Rolex Retailers and Service Centres covers more than 100 countries around the world and draws on the expertise of highly skilled watchmakers, carefully selected and trained by Rolex. For a list of Official Rolex Retailers and Service Centres, please visit rolex.com. Official Rolex Retailers can advise you on all the technical aspects of your watch's functions. Whether your bracelet needs sizing or it is time for a complete service, highly qualified Rolex watchmakers are on hand worldwide to meet all of your service needs.
