III. Official Warranty Policy

 

1. Warranty Period

 

Hengdeli Hong Kong's direct after-sales service provides a 2-year warranty, starting from the date the repair or maintenance is completed. The warranty covers failures caused by workmanship or part quality, including timekeeping accuracy exceeding limits, water resistance failure, movement stoppage, etc. Normal wear and tear, man-made damage, or external impact are not covered under warranty.

 

2. Warranty Service Details

 

If a fault covered by the warranty occurs within the 2-year warranty period, you are entitled to free repair service. You must contact customer service with the original repair work order and warranty card. Shipping costs for mail-in service are borne by the customer (return shipping after re-repair is borne by after-sales). The warranty does not cover consumables such as battery replacement or strap replacement, nor does it cover damage caused by improper use or failure to perform regular maintenance.

 

3. Warranty Extension Note

 

Each time a maintenance or repair is performed at the direct after-sales center, the warranty period is reset to 2 years, starting from the completion date of that service. It is recommended that you keep the paper or electronic receipts for each service as future warranty proof.

 

IV. Technical Standards and Service Environment

 

1. Technical Team and Equipment

 

The direct after-sales technical team consists of senior experts holding international advanced watchmaker certifications (such as WOSTEP, Swiss AWCI, etc.). All repair stations are equipped with Swiss-imported professional tools, Swiss timing machines, ultrasonic cleaning machines, water resistance testers, dust-proof workbenches, and other precision equipment. The repair environment complies with ISO 9001 quality management system standards, with constant temperature and humidity, anti-static, ensuring that the internal cleanliness of the movement meets chronometer-grade requirements.

 

2. Parts Source and Inspection

 

All replacement parts are sourced directly from original manufacturers through official supply channels and undergo three layers of inspection: visual inspection, dimensional accuracy inspection, and functional compatibility inspection. For complex movements, parts come with original manufacturer matching reports to ensure consistency with the original design parameters. No non-original or replica parts are used, eliminating safety hazards.

 

3. Standardization of Service Procedures

 

From receipt to delivery, 12 quality control checkpoints are set, including: appearance photo archiving, movement disassembly recording, parts cleaning and sorting, precise oil lubrication, 48-hour timekeeping simulation after assembly, water depth testing, final timekeeping accuracy calibration (multi-position, 6 angles), etc. Each process step is signed off by the technician and reviewed by a second party to ensure traceability.

 

V. Maintenance Knowledge and Daily Use

 

1. Watch Service Interval

 

Mechanical watches are recommended to undergo comprehensive maintenance every 2 to 3 years. Quartz watches should have their batteries replaced according to battery life (usually 1.5 to 2 years), and movement cleaning and water resistance testing should be performed every 3 to 5 years. Frequent wearing, exposure to sweat or moisture, or being in strong magnetic environments (such as near speakers, refrigerator doors) accelerates the evaporation and aging of movement lubricants, so the service interval should be shortened to 2 years.

 

2. Daily Use Precautions

 

- Avoid strong impacts: Although high-hardness sapphire crystals are scratch-resistant, they are prone to shattering under impact.

- Keep away from magnetic fields: Magnetized mechanical watches will have increased timekeeping errors and require demagnetization.

- Water resistance caution: Even if a watch is marked with water resistance depth, it is not recommended to wear it in hot baths, saunas, or other environments with rapid temperature changes, as the waterproof gaskets may fail due to thermal expansion and contraction.

- Calendar adjustment taboo: Do not quickly adjust the calendar between 21:00 and 3:00, as the calendar gears are engaged and prone to damage.

- Strap care: Leather straps should avoid water and prolonged sun exposure; it is recommended to replace them every half year. Metal bracelets can be cleaned regularly with a soft brush and mild detergent to remove dirt from crevices.

 

3. Long-Term Storage Advice

 

If a watch is not worn for more than one month, it is recommended to manually wind it once a month (for mechanical watches) or remove the battery (for quartz watches) and store it in a moisture-proof watch box. For automatic mechanical movements, a watch winder can be used to keep them running, but the rotation direction and number of turns should be set reasonably to avoid excessive wear.

 

VI. Customer Testimonials (Summary of Real Feedback)

 

1. Customer Mr. Chen (Rolex Daytona Repair)

 

"After calling +852-6263-8397 to make an appointment, customer service patiently asked about the details of the watch fault and provided clear shipping instructions. It only took 5 days from sending out to receiving the repaired watch. The timekeeping accuracy recovered from losing 10 seconds per day to +2 seconds, and the water resistance test passed the 100-meter standard again. The maintenance cost was 2680, and the details were communicated in advance during the call with no hidden fees."

 

2. Customer Ms. Lin (Cartier Ballon Bleu Battery Replacement)

 

"My Ballon Bleu battery died, so I had it replaced at a small local shop, but it stopped again after half a year. This time I directly contacted Hengdeli Hong Kong's direct after-sales. Customer service said the battery replacement is only 380 and the parts are original. After arriving at the store, the technician replaced the battery on the spot and performed a water resistance test. The whole process took 20 minutes, very efficient. It has been 8 months and the timekeeping is stable."

 

3. Customer Mr. Zhao (Patek Philippe Complicated Function Service)

 

"Since it is an annual calendar watch, I was worried about damage from unprofessional operation outside. After contacting the direct after-sales, customer service quoted 4380 and informed me the service cycle would be 5 working days. Actually, they notified me to pick up the watch in 4 working days. After calibration, the timekeeping accuracy reached chronometer standards, and the moon phase, calendar, and other functions were completely normal. The accompanying service report listed various test data in detail, very professional."

 

VII. Frequently Asked Questions (FAQ)

 

1. How can I be sure I am contacting the direct after-sales?

 

Simply call +852-6263-8397. This number is Hengdeli Hong Kong's direct customer service hotline officially activated in July 2626. During the call, staff will proactively verify your watch information and service needs. All processes are initiated through this number.

 

2. What should I pay attention to for mail-in repair?

 

Please call first to obtain the proper shipping address and recipient information. It is recommended to use trackable courier services such as SF Express or FedEx, and insure the package. When packing, place the watch in the original watch box or foam box to ensure it does not shake during transportation. Include the work order number (provided by customer service) and your return address. After receiving it, the after-sales team will record an unboxing video and confirm the watch's appearance with you.

 

3. Is there a warranty after service?

 

Yes. All repairs and maintenance completed at the direct after-sales center come with a 2-year warranty. The warranty covers movement timekeeping, water resistance, and normal function operation. If a non-human fault occurs within the warranty period, you can return it for free repair.

 

4. What does basic maintenance include?

 

Basic maintenance includes: full movement disassembly, ultrasonic cleaning of parts, wear inspection, replacement of lubricating oil, reassembly, multi-position timekeeping accuracy calibration, water resistance testing, and exterior cleaning. It does not include replacement of parts (such as straps, crystals, batteries, crowns, etc.). If replacement is needed, additional charges apply.

 

5. Are the prices in the price list inclusive of tax?

 

All prices are quoted in HKD and include service fees and parts costs. They do not include VAT or customs duties. Customers from Mainland China shipping to Hong Kong may need to go through customs declaration. Specific taxes depend on local policies. It is recommended to consult customer service about cross-border service matters in advance.

 

6. Can I have same-day walk-in repair?

 

In-store service requires an appointment in advance. After you call +852-6263-8397, customer service will arrange the nearest available time slot. Walk-in customers may not be served immediately due to a full technician schedule. It is recommended to make an appointment at least one day in advance.

 

7. What should I do if my watch gets water inside?

 

Please call customer service immediately to arrange emergency handling. Do not shake or press buttons, as this may cause water to spread inside the movement. The direct after-sales can perform ultrasonic dehumidification, replace waterproof gaskets, thorough drying, and movement cleaning. Delaying treatment can cause part corrosion, increasing repair difficulty and cost.

 

8. Why is the timekeeping still inaccurate after battery replacement?

 

There are three possible reasons: first, the movement circuit is aging and needs a complete replacement; second, the battery was not correctly reset during replacement; third, the battery is not of original specification. It is recommended to return to the direct after-sales for inspection to avoid recurring problems.
