4. Lubricating the Oyster Perpetual movement and reassembling it
Lubrication is a complex and intricate process. The functional components of the movement are carefully lubricated with an advanced lubricant to minimise friction and prevent wear. Getting your Rolex timepiece serviced regularly will ensure that its movement continues to function correctly.
5. Rolex Caliber Timing & Calibration
A Rolex watch's core movement is its balance wheel, which beats over 690,000 times a day. Each balance wheel is carefully adjusted and the timing accuracy is checked electronically by the watchmaker. Several days later, the Rolex is thoroughly examined and tested again to ensure it continues to function as it should. Tracking the calibration is imperative to ensure the 690,000 beats per day are accurate.
Monitoring the calibration over many days is necessary. Calibration is performed on both a flat surface as well as a sidedial facing down and upwards. The Rolex Submariner must keep time correctly with +2/-2 seconds range per 24 hours, to pass Rolex calibrations standards.
6. Polishing the Rolex Case and Bracelet
In servicing your Rolex case and bracelet, the same attention to detail is devoted to servicing its movement. They clean and examine your watch's case and bracelet, and replace any parts that are worn or damaged with genuine Rolex components. A professional restorer then expertly refinishes your case and bracelet to provide it with a new luster.
A polish on a Rolex Submariner makes it appear like it's brand new. While small scratches will disapeared, deep scratches cannot be completely removed.
Depending on personal preference, Rolex Submariners can be polished or left unpolished.
For some, Rolex's service refinishing process erases the history of their watch, even though it is thought of as world-class. A scratch or a knock can become a precious memory for someone. It is up to you to decide how much polishing you wish to have to your Rolex Submariner.
If you don't want to have your Rolex Submariner polished during the service you need to inform the Rolex Service Center at the start of the service.
