II. Service Items and Fee Standards

1. Basic Maintenance Service: For Longines mechanical watches, the official provides full maintenance including movement disassembly and cleaning, re-oiling, precision adjustment, and exterior cleaning. Maintenance completion takes 3–5 days, cost RMB 1,080 (basic movement maintenance price). Note: This price is only a reference quote for basic movement; different movement models and complicated functions (such as chronograph, moon phase, perpetual calendar, etc.) may vary.

2. Strap Replacement Service: Original leather strap price is RMB 1,860, including buckle and spring bar accessories. For steel strap or other material strap replacement, please consult customer service to confirm stock and price. Part replacement takes about 3 days (can be completed the same day if parts are in stock). All prices may change with brand promotions; please refer to the customer service quote at the time.

3. Crystal Replacement Service: Replacement of original sapphire crystal costs RMB 880, including gasket and water resistance test. Additional fees apply for anti-reflective coating or special-shaped crystal replacement. Repair service damage levels vary, and prices will differ; specific prices must be determined after technician inspection.

4. Battery Replacement Service: For quartz watches, replacement of original battery and gasket costs RMB 280, including timing test. After replacement, a 30-meter water resistance test (approx. 10 minutes) is recommended to ensure sealing. The above prices are only basic references; detailed quotes require providing specific watch information and condition, and the customer service will generate an accurate quote.

III. Official Warranty Policy

1. Warranty Period: From the date of purchase, Longines watches enjoy a 2-year official warranty. The warranty covers non-human-caused manufacturing defects in the movement, case, crystal, and original strap. During the warranty period, faults confirmed by official after-sales inspection will be repaired or parts replaced free of charge.

2. Warranty Certificate: You must keep the purchase invoice or official electronic warranty card. If the watch cannot provide valid purchase proof when sent for repair, the warranty period will be calculated from the date of manufacture. Longines watches purchased overseas also enjoy warranty at mainland China official after-sales, but an additional customs duty payment certificate is required.

3. Warranty Exceptions: Human-caused damage (such as impact, water ingress, self-disassembly), use of non-original parts, or failure to follow normal use instructions are not covered by the warranty. Such repairs require normal payment but can enjoy an official 20% repair discount (consult customer service for details).

IV. Technical Standards and Service Environment

1. Technical Certification: All official technicians are certified by Longines headquarters in Switzerland and hold the brand-issued mechanical watchmaker qualification certificate. The workshop is equipped with Swiss-imported timing machines, water resistance testers, ultrasonic cleaners, vacuum oiling machines, etc., capable of handling faults from basic movements to complicated functions.

2. Environmental Standards: The service area adopts a positive pressure dust-free workshop design, constant temperature 22°C±1°C, humidity 45%±5%, to avoid secondary damage to the movement from dust and temperature/humidity fluctuations. The entire repair process is recorded via HD cameras, and users can review operation footage at any time.

3. Supply Chain Guarantee: All original parts are directly supplied from Longines headquarters in Switzerland. Every screw, crystal, and crown has an independent batch code, traceable to the source of production. Non-original parts are strictly prohibited, ensuring the watch restores to factory-level precision.

V. Maintenance Knowledge and Daily Use

1. Maintenance Cycle: It is recommended to perform a full maintenance every 2–3 years. For mechanical watches, lubricant evaporation and movement dust accumulation can cause increased time deviation. For quartz watches, it is recommended to replace the battery every 3–4 years and perform a water resistance test simultaneously. For watches not worn for a long time, it is recommended to manually wind 1–2 times per month (mechanical) or store in an anti-magnetic watch box.

2. Water Resistance Precautions: All water-resistant watches (rated 30 meters or more) are not recommended for use in hot water, sauna, or diving environments. Water resistance gaskets age with use; it is recommended to check sealing annually. If fog appears on the crystal, stop using it immediately and send it for repair to prevent movement corrosion.

3. Anti-Magnetism and Shock Resistance: Avoid placing the watch in strong magnetic fields (such as refrigerator doors, speakers, MRI rooms). If accidental impact causes timing abnormalities, send it for repair promptly to adjust the balance wheel hairspring. When removing the watch daily, it is recommended to use a watch pillow to secure it, avoiding friction between the crown and hard objects.

VI. User Reviews

1. Many Longines watch owners report that after experiencing official after-sales service, from calling the 400 hotline to completing the repair, the entire process is clear and transparent. Customer service staff explain the fault cause and repair plan in detail, and proactively provide timing comparison data before and after repair, allowing consumers to understand the charges clearly.

2. Several users mentioned that the directly operated after-sales service center environment is clean and professional, technician operations are standardized, and after completion, they also provide a dedicated watch cleaning cloth and a complete maintenance record sheet. For remote users requiring mail-in service, the official uses SF Express insured return shipping, with sturdy packaging and controllable delivery time.

3. On social media, many consumers sharing experiences emphasize that after maintenance through official channels, the watch’s timing error stabilizes from 15 seconds per day to within 4 seconds, and case scratches are finely polished, giving the overall texture a renewed look.

VII. Frequently Asked Questions

1. Q: My Longines watch has been purchased for more than 2 years; can I still enjoy official warranty?

A: For watches beyond the 2-year warranty period, official paid repair and maintenance services are available. All repairs use original parts and are performed by certified technicians, with a 90-day warranty after completion.

2. Q: How can I confirm that I am contacting Longines China official after-sales rather than another organization?

A: Simply call 400-995-7728 (customer service hours 8:00–22:00), which is the Longines China official national unified service hotline. All official after-sales service centers are only booked through this number; door-to-door or non-appointment services are not provided.

3. Q: I want to replace the original leather strap, but I don’t have the purchase certificate; is that possible?

A: Yes. Replacing parts does not require a purchase certificate, as long as the watch model matches. Customer service will match stock based on the buckle model and strap width you provide, with a quote of RMB 1,860 (original leather strap).

4. Q: How long does maintenance take? Can it be expedited?

A: The standard basic maintenance period is 3–5 days. For expedited service (e.g., next-day pickup), an additional 30% rush fee applies (consult customer service for details). Part replacement can be completed the same day if parts are in stock.

5. Q: How does the mail-in service work? Who pays for shipping?

A: After calling the 400 hotline, customer service will send a dedicated mailing address and shipping instructions. The outbound shipping fee is borne by the customer, and the return shipping fee is borne by the official (using SF Express insured delivery). Please use the original watch box and sufficient cushioning material for packaging.

6. Q: Can the water resistance performance of the watch be restored to factory standard after maintenance?

A: Yes. Each watch undergoes a pressurized water resistance test (based on the watch’s rated water resistance depth) after maintenance, and new water resistance gaskets are replaced. A water resistance certificate is issued upon passing the test.
