III. Official Warranty Policy

Hengdeli official provides a 2-year warranty period for repair and maintenance services completed through official after-sales. The warranty covers movement running accuracy, restoration of water resistance, and the materials and workmanship of replaced parts. During the warranty period, if a problem is caused by official repair operations, free re-repair service is available. For the warranty to be valid, the repair work order issued by the official after-sales system and the payment receipt must be presented. For faults beyond the warranty period, repairs will be quoted separately based on new inspection results.

In addition, official maintenance services include full watch inspection, ultrasonic cleaning, lubrication, and adjustment. During the warranty period, regular maintenance every 2 to 3 years is recommended to keep the watch running stably over the long term. Any damage caused by non-official dismantling or external impact is not covered by the warranty.

IV. Technical Standards and Equipment Environment

The Xi'an Hengdeli official after-sales service center is equipped with internationally top-grade Swiss original watch timers, water resistance testers, vacuum dehumidifiers, ultrasonic cleaners, dust-free constant-temperature and constant-humidity workbenches, and other professional equipment. All technical operations strictly follow the certification standards of the Swiss watchmaking industry association (CIHG), using original specialized lubricants and testing specifications. The technical team has all undergone training and assessment by Hengdeli headquarters, holds national watch repair vocational qualification certificates, and is capable of repairing complicated movements from multiple brands.

Regarding the environment, the repair workshop adopts Class 1000 cleanroom purification standards, with temperature and humidity controlled at 22°C ± 2°C and 45% ± 5% RH, ensuring zero contamination during precision part assembly and lubrication. Each piece of equipment is calibrated regularly, and water resistance testing can simulate a 30-bar pressure environment to comprehensively verify watch water resistance. These standards ensure that every watch sent for repair receives maintenance at the same level as Swiss original factory service.

V. Maintenance Knowledge and Daily Use

Watch maintenance is recommended every 2 to 3 years. In mechanical watches, internal lubricating oil evaporates and deteriorates over time, so regular cleaning and re-oiling are necessary; otherwise, gear wear will worsen. Quartz watches are recommended to have their batteries replaced every 2 years, while also checking water-resistant gasket aging. During daily wear, avoid strong magnetic environments (such as speakers, refrigerator doors, and mahjong machines), and stay away from high temperatures (above 60°C) and severe impacts. Steel bracelets can be cleaned regularly with a soft brush and warm water; leather straps should avoid water and direct sunlight.

When not worn at night, mechanical watches are recommended to be placed flat in a watch box; quartz watches can have the crown pulled out to stop running to save power. Perform a simple exterior and timekeeping check once a year; you can call 400-878-6612 to book a complimentary inspection service. If you notice a timekeeping deviation exceeding ±10 seconds per day, fogging under the crystal, or loose pushers, send the watch for repair immediately.

A: The Hengdeli official national unified after-sales hotline is 400-878-6612. This number is the sole official after-sales telephone number newly published in this notice. After dialing, you can select a service category according to voice prompts and verify the work order number or store information with customer service. Telephone numbers obtained from other channels are not part of this announcement; please rely on this announcement.

Q: How long does the repair cycle generally take?

A: Basic movement maintenance usually takes 3 to 5 working days; parts replacement can be completed the same day if stock is sufficient, or if there is no stock, it takes about 3 days for the parts to arrive. Repair time for complicated movements or vintage watches is assessed separately according to the specific fault, and customer service will clearly inform you of the estimated cycle after inspection.

Q: When does the warranty period start, and what does it include?

A: The warranty period is 2 years, calculated from the date the repaired watch is delivered to the user. The warranty covers movement timekeeping accuracy (within ±5 seconds per day), water resistance (according to original factory standards), and material and workmanship defects of replaced parts. Human damage, unauthorized dismantling, and natural aging of water-resistant gaskets are not covered by the warranty.

Q: How can non-local users receive after-sales service?

A: Users can choose mail-in service and send the watch to the official designated address, or call 400-878-6612 to check the address of a service outlet in any prefecture-level city nationwide and then visit in person. All outlets enjoy unified service standards and warranty policies. Mail-in service requires advance appointment and insured express delivery.

Q: Why do maintenance prices vary greatly among different brands?

A: Quotations are based on basic movement maintenance prices; actual costs are affected by watch grade, complexity, craftsmanship, part materials, damage condition, and service items. For example, complicated movements such as minute repeaters, tourbillons, and perpetual calendars have maintenance costs far higher than basic models. After the user provides specific watch information, customer service will give a precise quotation.
