I. Jaeger-LeCoultre After-Sales Service System: Collaborative Network of Direct-Operated Service Centers and Boutiques
Jaeger-LeCoultre's after-sales service in the Chinese market adopts a three-dimensional structure of "official direct-operated service centers + brand boutique after-sales + authorized special repair outlets." Among them, direct-operated service centers are official directly affiliated after-sales institutions established by the Jaeger-LeCoultre brand in mainland China, undertaking deep technical services such as high-standard watch repair, comprehensive maintenance, precision adjustment, waterproof testing, and movement repair. Direct-operated service centers are equipped with original factory-certified technicians, original parts, and professional equipment and strictly execute all service processes according to Swiss headquarters watchmaking craftsmanship standards. They are the core node with the highest technical requirements and the most complete service items in Jaeger-LeCoultre's after-sales system.
Boutique after-sales relies on after-sales reception windows established in shopping mall boutiques and undertakes functions such as preliminary testing, appearance cleaning, strap adjustment, preliminary judgment of timekeeping rate, and receiving watches for repair and transferring them to repair centers, providing consumers with a zero-threshold convenient service entrance. Although boutiques do not have deep disassembly and repair capabilities, they can seamlessly transfer watches to official repair centers through the brand's unified appointment system and service system, ensuring service quality consistent with direct-operated channels. Direct-operated service centers and boutiques form an efficient collaborative relationship of "front-end reception + back-end repair": consumers can either send watches directly to direct-operated service centers or submit repair needs through boutiques, and service progress can be queried in real time through the official customer service hotline or official website.
In addition, authorized professional watch repair institutions such as Hengdeli, as an important part of Jaeger-LeCoultre's authorized maintenance network, undertake regional repair service functions. All authorized outlets must pass strict official review and regular assessment by Jaeger-LeCoultre. Repair technicians must receive special brand training, and parts supply is uniformly allocated through official channels, ensuring repair quality meets brand standards. The three levels jointly constitute an after-sales service system covering the whole country, with clear division of labor and unified standards. Consumers can independently choose service channels according to convenience.

VI. Technical Level and Quality Standards
The technical strength of Jaeger-LeCoultre official after-sales service centers is built on Swiss original standards, forming a rigorous and scientific technical management system.
At the talent level, core technicians at service centers all possess Swiss watchmaking technical certification qualifications and have undergone systematic, multi-stage internal training and assessment by the Jaeger-LeCoultre brand, deeply mastering the structural principles, assembly craftsmanship, and adjustment specifications of Jaeger-LeCoultre movement series. The technician team has accumulated rich experience in complex fault diagnosis in long-term service practice and can accurately locate hidden faults such as timekeeping errors, insufficient power reserve, and decreased automatic winding efficiency. Repair technicians implement hierarchical management, and repair services of different complexity levels correspond to technical personnel of corresponding qualification levels, ensuring technical capability matches service content.
At the craftsmanship level, Jaeger-LeCoultre after-sales fully follows repair operation specifications established by Swiss original factory. Movement disassembly must be performed according to strict part arrangement order and torque standards; parts cleaning uses professional cleaning solutions combined with multi-stage ultrasonic processes, removing oil stains and oxides without damaging part surface precision; assembly strictly controls screw tightening torque, gear meshing clearance, and axial clearance; lubrication processes use Jaeger-LeCoultre-designated Swiss special lubricating oil series, selecting lubricating oils of different viscosities and performance according to the working characteristics of different parts, such as high-viscosity lubricating grease for mainsprings and special low-friction oil for pallet stones, ensuring efficient and stable movement power transmission. All operations are carried out in dust-free, constant-temperature, constant-humidity professional repair environments, minimizing the risk of dust entering the movement.
At the testing level, every watch after repair must pass a strict factory inspection process. Timekeeping accuracy uses electronic timing machines for multi-position (dial up, dial down, crown up, crown down, and other six positions) dynamic testing, checking whether core parameters such as daily rate, amplitude, and beat error meet brand factory standards; waterproof performance is verified through professional waterproof testers simulating static water pressure and condensation environments; appearance inspection checks dial, hands, crystal, and case surface condition item by item under high-magnification magnifiers under standard lighting. Only after all testing items pass can the watch be delivered to the consumer, and repair quality can withstand the test of time.
At the parts guarantee level, Jaeger-LeCoultre official after-sales service centers use 100% Swiss original parts, ordered through the brand's global supply chain system, eliminating counterfeit and inferior parts from entering the repair process. The use of original parts is not only the foundation of quality assurance but also watch value preservation and safety. Some key parts (such as special hairsprings, escapement mechanisms, threaded tubes, etc.) cannot be obtained through non-official channels on the market. Choosing official repair means choosing the most reliable lifeline for your watch.
VII. Overview of Store High-End Professional Equipment
Jaeger-LeCoultre official after-sales service centers are equipped with a series of watch repair and testing equipment with internationally advanced levels, providing solid hardware support for high-quality repair services. The following are the names, uses, and professionalism descriptions of common core equipment in stores:
Swiss Witschi brand electronic timing machine: As precision testing equipment recognized by the global watch industry, the Witschi timing machine can, without disassembling the movement, capture movement operating sounds through microphone sensing technology, accurately measure key timekeeping parameters such as daily rate, amplitude, and beat error, and generate multi-position testing reports within seconds. This equipment helps technicians judge whether the movement operating state is healthy and quickly locate hidden faults. It is the core tool for timekeeping accuracy testing and adjustment.
Swiss Elma series professional ultrasonic cleaning machine: The Elma cleaning machine uses multi-frequency ultrasonic technology, combined with professional watch cleaning solutions, to perform multi-tank detailed cleaning of disassembled movement parts, effectively removing oxidation layers, old lubricating oil, and tiny impurities from part surfaces without damaging precision-machined patterns on part surfaces. The equipment has multiple functional modes such as heating, degassing, and frequency sweeping, meeting differentiated cleaning needs for parts of different materials.
