At AG Watch Repair Center, we often see luxury watches that haven’t been serviced in years. A recent case involved a Rolex Submariner 116613LB—also known as the “Two-Tone Blue Sub”—a classic favorite among Rolex enthusiasts.
The client had owned the watch for seven to eight years and admitted it had never been serviced. Recently, the Submariner started showing noticeable timing issues, prompting a visit to our workshop.
Timekeeping deviation is one of the most common issues for mechanical watch owners, and the causes can vary—worn components, dry lubrication, or inadequate winding are all potential culprits. In cases of serious deviation, professional servicing is essential.
Let’s walk through the complete lubrication and maintenance process for this Submariner, powered by the robust Rolex Calibre 3135 movement.
🔧 Rolex Lubrication & Maintenance Process
Step 1: Timing Test with Watch Analyzer
We begin with a timing test using a precision timing machine to evaluate the watch’s accuracy, amplitude, beat error, and overall performance. This helps us confirm the need for servicing.
Step 2: Disassemble Case and Movement
The watch case is opened carefully, and the movement is fully removed. Hands are detached, and the entire mechanism is disassembled using specialized tools—every screw, gear, and jewel comes apart.
Step 3: Inspect for Wear and Damage
Each part is inspected under magnification for wear, rust, or damage. If any components are too worn or broken, we recommend replacement before proceeding.
Step 4: Clean & Degrease Components
Using a watch-grade cleaning solution, all movement parts are placed in an ultrasonic machine to remove old oil and debris. After cleaning, the components are air-dried with care.

Step 5: Reinspect After Cleaning
A second inspection ensures all cleaned parts are in excellent condition and safe for reassembly.
Step 6: Reassembly & Lubrication
Each component is reassembled in proper sequence, with fresh high-grade lubricants applied to key friction points to reduce wear and ensure smooth operation.
Step 7: Reinstall Hands and Case
Once the movement is running smoothly, we reinstall the hands and seal the case back securely.
Step 8: Final Testing – Waterproofing & Accuracy
Before returning the watch, we perform pressure testing for water resistance and a final timing check to ensure accuracy and reliability.
