Rolex recommends servicing their watches every 10 years, but this can vary depending on usage and environment. If you wear your Rolex every day or expose it to extreme temperatures or water, it may require more frequent servicing. Additionally, if you notice any issues with your Rolex, such as timekeeping or power reserve problems, it may need to be serviced sooner. Regular servicing involves disassembling the watch, cleaning the internal components, replacing any worn or damaged parts, and reassembling and testing the watch to ensure it meets Rolex's precision and water resistance standards. It's important to have your Rolex serviced by a professional watch maker. It is adviced to bring your Rolex to service centre within the warranty period. However, the service charges will be much higher when the warranty is ended. You may consider to do servicing in Aristo as there are professional watch makers with reasonable charge. Additionally, regular servicing can prolong the life of your Rolex and ensure its continued accuracy and reliability.
