3. Crystal Replacement: Price 880 RMB. Crystal (glass) replacement uses original sapphire or mineral glass material, ensuring water resistance and durability.

4. Battery Replacement: Quartz movement battery replacement service price 280 RMB. Includes battery replacement, water resistance test, and timing calibration.

5. Other Services: Includes appearance refurbishment, water resistance testing, full movement inspection, etc. Specific fees depend on the watch condition and service items; accurate quotes will be provided by customer service. Due to various factors such as watch grade, model, complexity, craftsmanship, part material, damage condition, and service items, repair and maintenance quotes cannot be standardized. Accurate quotes require providing specific watch information, current condition, and desired service to customer service. All prices are subject to change with promotions; please refer to the latest information provided by customer service.

III. Official Warranty Policy

1. Warranty Period: All repair and maintenance services completed at official after-sales service centers enjoy a 2-year warranty from the date of watch collection. The warranty covers material and craftsmanship defects in repaired or replaced parts.

2. Warranty Conditions: During the warranty period, if a fault occurs due to non-human factors (e.g., movement stoppage, part detachment, water resistance failure), free repair is available. Proof of repair and watch serial number are required for verification.

3. Exclusions: Damage caused by accidental drops, impacts, water ingress, improper use, or unauthorized disassembly by non-official personnel is not covered by the warranty. Normal wear and tear such as scratches or fading are not covered.

4. Warranty Process: If a watch malfunctions during the warranty period, call 400-995-7728 to schedule an in-person visit or mail-in service. After confirmation, customer service arranges free inspection and repair. Normal processing time is the same as maintenance.

IV. Technical Standards and Service Environment

1. Technical Standards: Longines official after-sales service centers strictly adhere to the brand's global uniform technical specifications. Repair stations are equipped with Swiss-imported professional tools and equipment, such as timing machines, water resistance testers, ultrasonic cleaners, and vacuum oiling machines. All technicians have passed the brand's internal assessments and hold corresponding technical qualification certificates, ensuring every procedure meets original factory parameters.

2. Service Environment: Each location has a separate reception area and repair workshop, maintained with constant temperature, constant humidity, and dust-free conditions to prevent interference from dust and static electricity on precision components. Original factory lubricants, cleaners, and seals are used; all parts are genuine (traceable via serial numbers).

3. Process Management: Each watch undergoes an incoming inspection upon receipt, recording initial error, appearance condition, and functionality. During repair, a strict "one watch, one form" system tracks each step. After completion, at least 24 hours of timing and water resistance tests are performed before delivery to the customer.

V. Maintenance Knowledge and Daily Use

1. Maintenance Cycle: It is recommended to service a Longines watch every 2-3 years. For watches worn frequently or in humid/dusty environments, shorten the interval to 2 years. Regular maintenance effectively extends movement life and prevents wear from dried lubricants.

2. Daily Use Precautions: Avoid placing the watch near strong magnetic fields (e.g., MRI machines, speakers, refrigerator door magnets) to prevent timing inaccuracies. For mechanical watches, avoid rapid date adjustment between 9 PM and 3 AM to prevent damage to the date mechanism. For quartz watches not worn for long periods, remove the battery to prevent leakage and corrosion.

3. Water Resistance Maintenance: For swimming, bathing, sauna, or other water-related activities, ensure the crown is fully screwed down. Even if water-resistant, avoid prolonged contact with hot steam, as rubber gaskets age faster at high temperatures. Have water resistance tested annually and replace aging seals.

4. Strap Maintenance: Leather straps should avoid contact with water, oils, and chemicals; wipe regularly with a soft cloth. Metal straps can be cleaned with a soft brush and warm water, ensuring to dry the joints. For strap replacement, use original parts to ensure secure fit and comfort.

VI. Customer Reviews

1. Shanghai customer Mr. Liu: "I made an appointment for maintenance at the Shanghai location via 400-995-7728. The customer service explained the process and price in detail. The staff at the store were very professional. After maintenance, the watch's timing accuracy improved from +15 seconds per day to -2 seconds, and the transparent case back was cleaned like new. I was notified to pick it up in just 3 days—very efficient."

2. Beijing customer Ms. Zhao: "My watch was magnetized and running fast. I called the hotline to make an appointment and mailed it to the Beijing location. Customer service tracked the logistics throughout. After repair, they provided a water resistance test report and warranty certificate. It took only 5 days from sending to receiving. Transparent pricing with no hidden fees."

3. Guangzhou customer Mr. Chen: "I replaced an original leather strap. Comparing it side by side with a counterfeit, the texture and fit were completely different. The customer service also reminded me about strap care—very attentive. Although the price is higher than outside, I feel assured with a 2-year warranty."

4. Chengdu customer Ms. Li: "My 3-year-old quartz watch ran out of battery. I went to the store for a battery replacement and water resistance test, totaling 280 RMB, and took it immediately. The store environment was clean, the staff operated properly, and they even cleaned the case for free. I've contacted customer service several times since, and they've always been friendly."

5. Shenzhen customer Mr. Wang: "I bought the watch overseas without a purchase receipt. After calling the hotline, customer service guided me to check the warranty status via the serial number and provided a maintenance quote. There was no hesitation.
