The following will explain what to expect during a Rolex Service.
1. The Rolex Datejust watch is disassembled

During the service, the Rolex Datejust will be disassembled starting with removing the band from the Oyster case, opening the case, and removing the mechanical movement.
2. Rolex perpetual movement cleaning
'The movement is dismantled and each component is ultrasonically cleaned in a special formulated solution' (source: Rolex Service Documentation)
Rolex specially formulated cleaning solutions are used to clean the movement in an ultrasonic machine after it has been disassembled.
This procedure will completely remove any salt, dirt, grease and chemicals, and other residues that have penetrated inside the Rolex watch.
3. Rolex watches wearable components replacement
'A Rolex watchmaker closely examines each individual component of the movement and identifies which components require replacement. Only genuine replacement parts supplied directly by Rolex Headquarters in Switzerland are used' (source: Rolex Service Documentation)
Every element of the Rolex Datejust is carefully scrutinized by the watchmaker. A mainspring, for example, is one of the components that needs replacing.
Rolex replaces any old components of your Rolex with new ones. You should be cautious in this situation. During a full service appointment, they will replace any worn or broken parts that could make your Rolex unique and collectible. The modern Rolex series does not use a specific glass manufactured during a specific period. Rolex watchmakers will replace an ageing glass with a new Rolex crystal when it is worn. It will affect how much your Rolex is worth on the collector's market if you do not have the old original component.
Please be as specific as possible when you authorize Rolex to replace element of a old or vintage Rolex Datejust.
4. Reassembling of the Rolex Datejust watch and lubricating the movement.
'Using the most advance lubricants, each functional component of the movement is carefully lubricated to minimise friction and prevent wear. This ensures that the movement of your Rolex timepiece will continue to perform accurately.' (source: Rolex Service Documentation)
There are many owners who are misinformed, believing that oiling simply lubricates the movement, and for that reason find that the Rolex service appointment is costly. Understanding the entire process, however, is imperative when it comes to understanding the value of the Rolex Service. Lubrication is a detail and complicated process.
5. Calibration of the Rolex Datejust
'The heart of your Rolex watch movement is its balance wheel, which has a frequency of over 690,000 beats per day. To ensure timekeeping precision, the watchmaker meticulously adjusts the balance wheel and electronically tests its timing accuracy. Your Rolex is then thoroughly tested and carefully observed over a period of several days to verify its performance.' (source: Rolex Service Documentation)
There are approximately 690,000 beats every day, so tracking the calibration to make sure it is accurate is imperative. The watchmaker will spent several days monitoring the calibration. Service observations are not only of the Rolex Datejust sitting flat, but also sitting on the sidedial, facing down and up. Ensure that the watch is also timed correctly, namely +2/-2 seconds each day, before returning it.
6. Refinishing the Case and Bracelet.
'The same keen attention to detail that is devoted to servicing the movement of your Rolex also goes into servicing its case and bracelet. After the initial cleaning, the case and bracelet of your watch are closely examined, and any worn or damaged components replaced with genuine Rolex parts. Your case and bracelet are then expertly refinished and ultrasonically cleaned to restore lustre.' (source: Official Service Documentation)
When a Rolex Datejust is polished during service, its luster will be restored almost to its original condition. There will be no complete removal of deep scratches, but small scratches will be repaired.
A polished or unpolished Rolex Datejust during the watch service is a matter of personal choice.
Although Rolex service refinishing is a world-class process, some hate the idea of erasing their watch history with it. Some people want to keep their life memories, including watch scratches and knocks. The choice of whether or not to polish your watch during the service depends on your preference. The service charge include the watch refinishing, it will not reduce the service costs to opt out. When you begin the Rolex service, you can request that the Rolex Service Centre not polish your Rolex Datejust.
7. Reassembling the watch case.

Rolex Datejust gaskets are wearable components that are automatically replaced when the watch is serviced. The service uses the same standards as the Rolex factory in Switzerland, Rolex Service Centres will reassemble your Rolex timepiece.
8. Watch waterproof tests
A rigorous testing process ensures the watch case complies with water resistance requirements. Through three tests - a vacuum test, compression test, and condensation test - any amount of leakage could be detected inside the case.
It is harmful for any watch if it gets wet or if it gets dusty. Watches from Rolex have a waterproof casing called the Oyster. The case and gaskets you receive back will be tested in the same manner as the ones factory tested when you purchased the Rolex Datejust.
9. Final watch Quality Control
'Rigorous quality checks are carried out at each stage of the servicing process. During the final check, the power reserve, timing accuracy and aesthetic appearance of your watch are verified one last time against manufacturing specifications to guarantee the highest possible standard of quality.' (source: Rolex Service Documentation)
Rolex Service adhere to the same quality control standards as Rolex manufactures in Switzerland.
10. Watches Service Warranty
You are covered by a two-year Rolex Service Guarantee after your Rolex has been serviced. A watch is not covered by this guarantee if it is damaged or degraded as a result of an accident or mishandling. In the event that any non-Rolex authorized third party intervenes or adds non-Rolex made parts or accessories, the Service Guarantee will be invalid. Rolex international warranty covers all work completed at a Rolex Service Center.
