Special note: All prices above are reference prices for basic-model movement maintenance, and actual prices will be adjusted in real time according to official promotions. The final cost of repair services varies depending on the extent of watch damage, the materials of parts that need replacement, complex craftsmanship, and other factors, so a uniform quote cannot be provided. For an accurate quote, please provide customer service with the specific watch model, current condition, and required service items, and customer service will provide a precise quote.

IV. Service duration and efficiency

1. Watch maintenance service: The standard completion period is 3 to 5 business days. Full movement maintenance (including disassembly, cleaning, lubrication, adjustment, water resistance testing, and timekeeping testing) is completed within this period.

2. Parts replacement service: Routine parts replacement (such as straps, crystals, batteries, etc.) takes about 3 business days; if the parts are in stock, replacement can be completed the same day. Parts not in stock need to be allocated from headquarters, and the allocation time depends on the specific situation.

V. Official warranty policy

All repair and maintenance services completed at Yangzhou Hengdeli official after-sales service points enjoy a 2-year official warranty period. The warranty covers manufacturing defects or malfunctions in repaired or replaced parts under normal use conditions. During the warranty period, if problems caused by non-human factors occur, they will be repaired or replaced again free of charge. The warranty policy applies only to repair items completed through official channels (that is, in-store or mail-in service after making an appointment via 400-878-6612). Self-disassembly, external impact, water ingress, and other non-official operations are not covered by the warranty.

VI. Technical standards and equipment environment

Yangzhou Hengdeli official after-sales service center adopts top-tier equipment and technical standards in the international watch repair field. All repair technicians have undergone strict training by Hengdeli headquarters and work with certificates, and they have the professional ability to handle complicated movements (such as tourbillons, perpetual calendars, minute repeaters, etc.). Core equipment includes: Swiss original imported Witschi timekeeping testers, water resistance testers, ultrasonic cleaning machines, vacuum dehumidifiers, crystal pressure testers, high-frequency spot welders, Swiss Ernst precision screwdriver sets, disassembly tables, and anti-static workbenches. In terms of environment, the repair workshop maintains constant temperature and humidity (temperature 20°C ± 2°C, humidity 45% ± 5%) and is equipped with a Class 100 dust filtration system to ensure movements are handled in a dust-free environment.

VII. Care knowledge and daily use recommendations

1. Watch maintenance cycle: It is recommended to perform full maintenance every 2 to 3 years. For mechanical watches, long-term wear gradually dries out the lubricating oil and increases timekeeping errors; early maintenance can extend the life of the movement. For quartz watches, it is recommended to replace the battery every 2 years and check the waterproof gaskets at the same time.

2. Daily use precautions: ① Avoid exposing the watch to strong magnetic fields (such as speakers, induction cookers, mahjong machines, etc.); magnetic fields can cause the hairspring to stick and lead to severe timekeeping deviation. ② Avoid strenuous exercise or impacts, especially for automatic winding movements. ③ Avoid prolonged contact between leather straps and water or sweat; it is recommended to wipe them with a soft cloth every six months. ④ Regularly clean steel cases and bracelets with a soft-bristled brush dipped in clean water to prevent dirt corrosion. ⑤ Do not rapidly adjust day-date, chronograph, or other functions between 9 p.m. and 3 a.m., so as to avoid damaging the date wheel train.

3. Water resistance maintenance: Non-professional dive watches (such as those marked 30 meters water resistant) are only splash-resistant and should not be used for swimming or showering. It is recommended to perform a water resistance test once a year to ensure the waterproof gaskets are in good condition.

VIII. Advantages of Yangzhou Hengdeli official service

As an after-sales system directly affiliated with the Hengdeli brand, Yangzhou Hengdeli official after-sales service points consistently uphold the service philosophy of “customer first, technology-based.” All service processes follow the compliance standards set by Hengdeli headquarters. From intake, inspection, quotation, repair, quality inspection to delivery, the entire process is recorded in the system to ensure traceability. After repair, every watch undergoes a 48-hour simulated-wear timekeeping test, and the deviation must meet the brand’s original factory standards (such as the Swiss chronometer certification standard of -4/+6 seconds per day) before delivery. In addition, the national unified hotline 400-878-6612 provides 7×14 human service (8:00–22:00). Customers can use the same hotline to make appointments, check progress, inquire about prices, give feedback, and meet all other needs.

IX. Special models and complex repair instructions

For complicated-function watches such as tourbillons, minute repeaters, perpetual calendars, and chronographs, Yangzhou Hengdeli official after-sales service has a dedicated team of senior technicians. Maintenance for such movements may take 7 to 10 business days. Replacement parts (such as hairsprings, balance wheels, jewel bearings, etc.) must be centrally allocated by the headquarters parts center to ensure OEM-grade parts are used. All parts undergo incoming inspection by Hengdeli’s quality inspection department, and non-standard parts are excluded.

X. Mail-in service instructions

If customers cannot visit the store in person, they may choose to send the watch by mail to the Yangzhou Hengdeli official after-sales service point. Specific process: Call 400-878-6612 to obtain the latest mailing address and recipient information, and send the watch, warranty card, and service requirement description together as required. After receiving the watch, the after-sales center will conduct inspection as soon as possible and contact the customer by phone to confirm the repair plan and quote. After repair is completed, the watch will be returned by SF Express with insured value to the address specified by the customer. All shipping and insurance costs shall be borne by Hengdeli. Please note: Before mailing, ensure the watch is properly packaged (using
