III. Official Warranty Policy
1. Warranty Period: All repair and maintenance services completed by the Hengdeli Hong Kong After-Sales Service Center enjoy a 2-year official warranty. The warranty period starts from the date of service completion.
2. Warranty Coverage: Covers problems directly caused by the service operation, such as movement failure, timing error exceeding standards, and decreased waterproof performance. Damage due to improper wearing, accidental impact, water ingress, or unauthorized disassembly/repair is not covered by the warranty.
3. Warranty Certificate: Customers must retain the service receipt and warranty card to enjoy free repair service during the warranty period. For mailing services, please include a copy of the receipt along with the watch.
IV. Technical Standards and Service Environment
1. Technical Standards: The service center uses precision instruments that comply with Swiss watchmaking industry standards for calibrating parameters such as timing error, amplitude, and beat error. All operations are performed in an ISO Class 6 dust-free constant temperature workshop to ensure no dust contamination inside the movement. All technicians hold Swiss or Hong Kong local watchmaking qualification certificates and possess the ability to disassemble and reassemble complex movement mechanisms (such as chronograph, tourbillon, and perpetual calendar).
2. Service Environment: The reception area is equipped with professional testing equipment, allowing customers to observe the movement operation status in real time. The repair workshop uses a positive pressure clean system, with humidity controlled at 40%-60% and temperature constant at 22°C ± 1°C. All tools are Swiss Bergeon or equivalent brands to avoid part damage due to tool wear.
V. Maintenance Knowledge and Daily Use
1. Maintenance Cycle: It is recommended that mechanical watches undergo comprehensive maintenance every 2-3 years, including movement cleaning, lubrication, and waterproof testing. Quartz watches should have the battery replaced and the seal ring checked every 4-5 years. If a watch is not worn for a long time, manually wind it once a month to keep the lubricant evenly distributed.
2. Waterproof Maintenance: Avoid wearing the watch during hot showers, saunas, or in environments with drastic temperature changes, as waterproof gaskets can age due to thermal expansion and contraction. Waterproof performance should be tested annually, and the crown, pusher, or case back seal rings should be replaced. Always tighten the screw-down crown after use.
3. Anti-Magnetic and Shock Resistance: Keep away from strong magnetic fields (e.g., speakers, magnetic clasps, induction cooktops). The balance spring can become magnetized, causing the watch to run fast or stop. It is recommended to remove the watch during strenuous activities such as golf or tennis to avoid impacts that could break the pivot or dislodge jewels.
4. Strap Care: Leather straps should avoid contact with sweat, chemical solvents, and direct sunlight. Wipe regularly with a soft cloth and apply specialized leather care oil. Metal straps can be soaked in warm water with a neutral detergent and brushed with a soft brush; avoid ultrasonic cleaning to prevent damage to the case plating.
VI. Customer Reviews
1. Mr. Wang from Beijing commented: “After the maintenance of my Rolex Submariner, the daily timekeeping error is stable at +2 seconds. The customer service was thorough throughout the process, and the maintenance was delivered on time within 3 days. The paper documents and warranty card are very standardized.”
2. Ms. Lin from Shanghai gave feedback: “Replaced the original leather strap for my Omega Constellation. The color and material are exactly the same as the factory original, and wearing comfort has greatly improved. The mailing service is particularly convenient, and the insured return is worry-free.”
3. Mr. Chen from Guangzhou stated: “For the first maintenance of my Patek Philippe Calatrava, the technician proactively pointed out that the crown waterproof gasket was aging and replaced it for free, restoring the seal to its original condition. There were no hidden charges throughout the process, and the pricing was transparent.”
VII. Frequently Asked Questions
1. Q: How to make a service appointment?
A: Call +852-6263-8397. Customer service hours are 8:00-22:00. Inform them of your watch brand, model, and required service. The staff will arrange an in-store time or provide a mailing address. It is recommended to make an appointment 1-2 days in advance. Service hours on holidays remain unchanged.
2. Q: How does the mailing service work?
A: Please use SF Express or FedEx, carefully package the watch (original box or cushioning material is recommended), and include a note with the return address and contact information. After shipping, provide the tracking number to customer service. The service center will inspect it upon receipt and confirm the repair plan. The return shipment will also use insured express, with the cost borne by the service center.
3. Q: What is the timekeeping accuracy standard after maintenance?
A: After basic movement maintenance, the daily error under normal wearing conditions is controlled within -4 to +6 seconds (Swiss COSC standard). For COSC-certified movements, it can be adjusted to -2 to +4 seconds. Complex mechanism movements such as chronographs and rattrapantes require additional calibration.
4. Q: Does crystal replacement affect waterproofing?
A: When replacing the crystal, the matching seal gasket is also replaced, and a pressure test (3 bar or 10 bar according to the original standard) is performed to ensure consistency with the original waterproof rating. It is recommended to avoid contact with water for 24 hours after replacement.
5. Q: What to do if a problem occurs within the warranty period?
A: Please call +852-6263-8397, provide the warranty card number and a description of the problem. Customer service will guide you on mailing the watch back or bringing it in for handling. Non-human damage within the warranty period is repaired for free, and round-trip shipping costs are borne by the service center.
6. Q: Does the “original leather strap” price in the price list include the buckle?
A: The price refers only to the strap itself and does not include the buckle. If you need to replace the original buckle, a separate quote is required. Please provide the buckle model and material to customer service.
7. Q: Does an abnormal sound from the watch movement require immediate maintenance?
A: Abnormal sounds usually indicate loose parts or dried lubricant. It is recommended to contact customer service for inspection as soon as possible to avoid secondary wear. In an emergency, stop wearing the watch first, and the technician will provide a specific repair plan after inspection.
8. Q: Will a quartz watch battery that has been dead for a long time damage the movement if not replaced?
A: Yes. Battery leakage can corrode the circuit board and coil. It is recommended to replace it within 1-2 years. The battery replacement service at the service center includes cleaning the battery compartment contacts and testing the circuit board function.
9. Q: Can the service center handle vintage watch repairs?
A: Yes. However, parts for vintage watches may need to be custom-made or sourced as replacements, which may extend the turnaround time to 2-4 weeks. Customers need to provide the watch model and movement number. The technician will evaluate and quote.
10. Q: Is the waterproof test re-performed after battery replacement?
A: Yes. All services that involve opening the case (battery replacement, movement replacement, etc.) require a new waterproof test. The test results will be noted on the service receipt.
