A Comprehensive Guide to Lange Watch Maintenance: The Nine-Step Overhaul Process
Ensuring your Lange timepiece maintains its precision, value, and beauty over the years requires regular maintenance. Lange recommends sending your watch for servicing every three to five years, encompassing a thorough process that includes cleaning, visual inspection, and rate adjustment. Here’s an in-depth look at the nine-step overhaul process, meticulously caring for every component of your Lange watch.
1. Assessment
Upon arrival at the service center, a watch technician will meticulously evaluate the condition of your watch. You will then receive a confirmation and a cost estimate for your approval.
2. Case Opening
After order confirmation, Lange technicians carefully disassemble your watch, separating the case from the movement and removing the hands and dial.
3. Disassembly
To prevent damage to the meticulously finished surfaces, the technician carefully disassembles the entire movement of your Lange watch. All components are thoroughly degreased and cleaned with a specialized solution.
4. Visual Inspection
Each component of the movement undergoes a detailed inspection. Some models require checking hundreds of parts. Any signs of wear, no matter how minor, lead to the replacement of the affected components.
5. Reassembly
The movement is then cautiously reassembled. All bearings and sliding surfaces are lubricated using an oil dispenser, a thin metal syringe that allows precise application of lubricant.
6. Rate Adjustment
After using a timing machine to check the movement’s rate, the technician adjusts it in five different positions. Minor adjustments are made to the balance spring, gradually fine-tuning the balance wheel to achieve the perfect oscillation frequency.
7. Comprehensive Function Check
Once the movement is reassembled, all mechanisms, such as the outsize date display, winding system, or any complications, are thoroughly tested to ensure flawless functionality. Adjustments are made as necessary until perfection is achieved.
8. Trial Run
The watch is placed on a device that simulates wrist movement and runs for several days to test the timepiece’s long-term accuracy.
9. Final Examination
After reinserting the movement into the case, the watch undergoes a second trial run for several days. The final inspection is rigorous and precise, examining the watch for any imperfections, testing water resistance and operational performance, and checking the rate accuracy for one last time.
By following these meticulous steps, your Lange watch remains a testament to precision engineering and timeless elegance. For any service needs, always turn to an authorized Lange service center.
