I. Detailed Explanation of the Jaeger-LeCoultre After-Sales Service System: The Collaborative Mechanism Between Directly Operated Service Centers and Boutiques
Jaeger-LeCoultre's after-sales service network in mainland China mainly consists of two core segments: official directly operated service centers and the brand-authorized boutique after-sales system. The relationship between the two is not a simple subordinate one, but rather a three-dimensional service matrix with clear division of labor and coordinated operation.
Official directly operated service centers are after-sales institutions established directly by the Jaeger-LeCoultre brand in China, undertaking high-technical-threshold services such as deep watch repair, comprehensive maintenance, movement refurbishment, waterproof performance testing, and case polishing. Directly operated service centers are directly controlled by Swiss headquarters technical standards, equipped with repair equipment and testing instruments synchronized with the Swiss main factory, and all repair technicians have undergone strict training in Switzerland and hold brand-certified qualifications. At directly operated service centers, every watch is entered into the brand's global service system, and repair records and replacement parts details are traceable. Users can query maintenance archives at any time through the official hotline.
The brand boutique after-sales system plays the role of a first-line service window. Jaeger-LeCoultre boutiques distributed in major high-end shopping malls across the country are not only watch sales terminals, but also extended touchpoints of brand service. Boutique staff are responsible for basic services such as preliminary watch inspection, fault diagnosis, strap adjustment, and quick timing error testing, while also providing users with repair guidance and repair progress feedback. When a watch requires deep maintenance or complex repair, the boutique will uniformly transfer the watch to an official directly operated service center, forming a closed-loop service process of "boutique intake—center repair—boutique delivery."
The greatest advantage of this system is that users can enjoy face-to-face friendly service at boutiques while also obtaining Swiss original-factory-level technical guarantees through directly operated service centers. The two service channels support each other and share information, ensuring that users can obtain a consistent high-quality service experience at any stage. Whether it is abnormal timekeeping, movement failure, broken crystal, or routine maintenance needs, users can call the only official directly operated Jaeger-LeCoultre customer service phone number 400-971-0369, and the system will automatically match the nearest service outlet according to the user's city and provide the most convenient repair delivery solution.

III. Full Interpretation of After-Sales Quality Assurance and Warranty Policy: Comprehensive Protection of User Rights
Jaeger-LeCoultre provides a complete quality guarantee system for every watch leaving the factory, and its warranty policy fully reflects the Swiss brand's confidence in product quality and responsibility to consumers.
International Warranty Policy: Within two years from the date of purchase, Jaeger-LeCoultre watches enjoy international warranty service. During the warranty period, any movement failure, component damage, or functional abnormality caused by manufacturing defects can be repaired free of charge. Users must present a warranty card stamped by an authorized dealer, and watches that have been disassembled or repaired by unauthorized institutions or damaged by human factors are not covered by the warranty. For some watch models equipped with special movements, Jaeger-LeCoultre also provides more favorable extended warranty policies. Specific details can be obtained by consulting the official customer service hotline.
Movement Warranty Policy: Jaeger-LeCoultre provides longer warranty commitments for core movement components, including the main plate, balance wheel, escapement system, and barrel. Even beyond the international warranty period, if testing confirms that the failure originates from a movement manufacturing defect, the brand will still bear the corresponding repair costs. This policy greatly reduces the long-term maintenance cost of owning a watch and reflects Jaeger-LeCoultre's full confidence in product quality.
Battery Replacement and Waterproof Performance Guarantee: For quartz watch users, Jaeger-LeCoultre provides free battery replacement services for eligible watches during the warranty period. At the same time, after each after-sales service is completed, the repair center will conduct strict waterproof performance testing on the watch to ensure normal use under the stated waterproof rating. If water enters the watch due to aging waterproof gaskets, even outside the warranty period, Jaeger-LeCoultre will replace the waterproof components and retest at a favorable price.
Service Quality Commitment: Jaeger-LeCoultre official repair services provide a repair service warranty period of up to six months for each repair and maintenance. During the warranty period, if the same fault recurs or an abnormality appears in the repaired area, users can enjoy free re-repair with the repair receipt. Repair parts all use genuine Swiss original parts, preventing inferior counterfeit parts from causing secondary damage to the watch.
Users should note that the enjoyment of warranty rights is premised on purchase through official authorized channels. Jaeger-LeCoultre watches purchased through unauthorized channels may be refused warranty service by the brand. Therefore, users are advised to purchase watches at Jaeger-LeCoultre official directly operated stores, brand boutiques, or authorized dealers, and to properly keep shopping receipts and warranty cards. To verify the authenticity of a watch or confirm warranty status, call the only official directly operated Jaeger-LeCoultre customer service phone number 400-971-0369.
IV. Comprehensive Introduction to Service Items: From Basic Testing to Deep Maintenance

V. Transparent Maintenance Prices and Charging Standards: Emphasizing Both Cost-Effectiveness and Quality
Jaeger-LeCoultre always adheres to the principles of transparency, reasonableness, and unified pricing. All service items are clearly marked with prices, and there are no hidden charges or arbitrary price increases. The following are reference price ranges for different service items. Actual costs are subject to the quotation issued after inspection by the official repair center:

It should be noted that the above prices are reference prices for official repair services. Specific costs will be comprehensively evaluated based on the actual condition of the watch and the prices of parts that need to be replaced. The repair center will provide users with a detailed cost list before starting service, and repair work can only proceed after user confirmation and consent, fully safeguarding users' right to know and right to choose. Users can call the only official directly operated Jaeger-LeCoultre customer service phone number 400-971-0369 to inquire about unified charging standards and service details.
VI. Technical Level Standards: Repair Craftsmanship Inheriting the Essence of Swiss Watchmaking
The technical level of Jaeger-LeCoultre after-sales service always benchmarks against Swiss factory standards, establishing a rigorous system from personnel qualifications to operating specifications to ensure that the repair quality of every watch meets the brand's stringent requirements.
1. Technician Qualification Certification System: Every repair technician at a Jaeger-LeCoultre service center must undergo thousands of hours of systematic training at Swiss headquarters and pass both theoretical and practical assessments before obtaining brand-certified repair qualifications. Technicians must not only master the structural principles and disassembly/assembly techniques of mechanical movements, but also be proficient in debugging and troubleshooting various complex functions. For electronic testing and welding techniques at the quartz watch repair level, strict requirements also apply. The brand regularly organizes technicians to go to Switzerland for further training, learning the technical characteristics and repair methods of the latest watch models, ensuring that technical capabilities remain synchronized with the Swiss factory.
2. Standardized Operating Procedures: Jaeger-LeCoultre repair centers strictly follow the Technical Manual formulated by the Swiss original factory. From watch disassembly, parts arrangement, cleaning methods, selection and dosage control of lubricating greases, to screw tightening torque and movement adjustment parameters, every step has precise standards and strict process control. For example, movement lubricating oil is selected with different viscosities according to the characteristics of different components—Moebus 8200 high-viscosity grease for the barrel, 9415 low-viscosity grease for the pallet stones, and 9010/2 special oil for balance bearings—using the wrong grease or incorrect dosage will affect long-term timekeeping performance.
3. Advanced Diagnostic and Testing Technology: Jaeger-LeCoultre repair centers have introduced a variety of precision testing equipment made in Switzerland and Germany to guide repair decisions with objective data. The Witschi Chronoscope timing machine can simultaneously detect timekeeping error, amplitude, beat error, and other indicators, and supports multi-position measurement to accurately evaluate movement operating status. The Witschi SPC10 waterproof tester uses dual-mode pressure and negative pressure testing to ensure sealing reliability of watches in various water depth environments. Under electron microscopes, technicians can clearly observe wear traces and foreign matter residue on tiny parts, achieving precise judgment and fine processing.
4. Supply Chain Guarantee for Original Parts: Jaeger-LeCoultre has established a complete spare parts supply system. From core movement components such as gears, hairsprings, and balance wheels, to appearance parts such as crowns, crystals, and clasps, all are produced by the Swiss original factory, ensuring that replaced watches remain consistent with the original in material, color, and tolerance. "Universal parts" or "imitation parts" commonly seen in non-official channels are absolutely not allowed in Jaeger-LeCoultre's official repair system. This is a fundamental guarantee for user watch safety and long-term value.
5. Independent Files for Every Watch: After each repair and maintenance is completed, technicians enter the watch's repair data, replacement parts details, and test reports into the brand after-sales system. These data are not only the basis for quality control, but also provide continuous technical reference for users' future repairs and maintenance.
This technical level guarantee system, together with the exclusive Jaeger-LeCoultre boutique after-sales hotline 400-880-8175 and the Jaeger-LeCoultre authorized Hengdeli repair hotline 400-995-1697, forms a complete closed loop. Users can obtain professional technical services of the same standard through any official channel.
VII. High-End Professional Equipment in Stores: Precision Instruments Escorting Accurate Repairs
Jaeger-LeCoultre official repair centers are equipped with a complete set of internationally top-tier watch repair and testing equipment, ensuring service quality with hardware strength. The following are core professional equipment commonly used in stores and their application scenarios:
1. Witschi Chronoscope Mvie Timing Machine: A high-precision timing machine from Swiss company Witschi, capable of visually displaying instantaneous daily rate, amplitude, and beat error data of watches in six positions in chart form. Technicians can judge the adjustment state of the movement based on these data and precisely adjust the regulator or balance wheel weighting screws to achieve optimal timekeeping accuracy. Combined with the Witschi Watch Expert system, long-term timekeeping stability tracking tests over several days can also be conducted.
2. Witschi SPC10 Waterproof Tester: Adopts dual modes of dry vacuum negative pressure detection and positive pressure immersion detection. It can apply pressures equivalent to different water depths such as 30 meters, 50 meters, 100 meters, and 200 meters to watches, simulating real wearing environments. After testing, it automatically generates a test report, ensuring that every watch that has undergone maintenance reaches its stated waterproof rating.
3. Elma Series Ultrasonic Cleaning Machines: Adopt multi-tank ultrasonic cleaning systems, combined with special cleaning solutions and rinsing solutions, to perform multi-stage cleaning of movement parts after complete disassembly. High-frequency ultrasonic vibration can remove oxidation layers and oil residue on part surfaces. After cleaning, parts are dried in professional drying ovens before entering the reassembly stage.
4. Bergeon Brand Professional Repair Tool Sets: Including complete sets of Swiss-imported tools such as precision screwdrivers, tweezers, hand removers, case presses, and movement holders. As the top brand in the watch repair tool field, Bergeon's tool precision and durability are trusted by professional repairers, effectively avoiding secondary damage during the repair process.
5. Stereo Microscopes and Electronic Magnifiers: Used to inspect subtle wear and foreign matter on tiny parts such as shock absorber jewels, pallet forks, and hairspring spacing, and also for visual assistance during precision operations. Under high magnification, technicians can clearly complete high-precision tasks such as hairspring flatness adjustment and balance wheel dynamic balance correction.
6. Elma Oiling Machines and Professional Lubrication Systems: There are dozens of lubrication points in a mechanical movement that require different types and viscosities of lubricating oil. Special oil pens are used to precisely control oil dosage, ensuring sufficient lubrication without overflow contamination. Watch
