IV. Official Warranty Policy

Hengdeli provides a 2-year warranty for all repair and maintenance services completed through official channels. During the warranty period, if a fault is caused by official workmanship or parts quality issues, you can enjoy free re-repair with the service receipt. The warranty covers core indicators such as movement operation, timekeeping accuracy, and water resistance. Please note that faults caused by external human damage, failure to operate according to usage instructions, or non-official disassembly and repair are not covered by the warranty.

V. Technical Standards and Equipment Environment

Hengdeli’s Dongguan after-sales outlet uses internationally leading equipment, including Swiss-imported Witschi timing machines, Elma ultrasonic cleaners, Bergeon professional tool sets, and anti-static workbenches. All repair operations are carried out in a constant-temperature, constant-humidity clean workshop, and environmental standards comply with ISO 9001 quality management system requirements. Technicians all hold technical certification certificates issued by Hengdeli headquarters and can perform full-process refined operations on movements, including disassembly, cleaning, lubrication, assembly, and adjustment.

VI. Maintenance Knowledge and Daily Use

① It is recommended to service a watch every 2–3 years. Mechanical watches require regular cleaning and lubricant replacement because long-term operation causes lubricating oil to dry out and wear to occur, which helps maintain timekeeping accuracy. If a quartz watch runs slow or the second hand jumps abnormally, the battery should be replaced promptly and water resistance tested.

② Daily wearing precautions: avoid contact with strong magnetic fields (such as speakers and microwave ovens), avoid severe shocks, and regularly wipe the case and strap with a soft cloth. Leather straps should avoid contact with water; metal straps can be cleaned periodically with a soft-bristled brush.

③ Water resistance should be tested once a year. Especially after contact with seawater or hot water, rinse with clean water and dry promptly. Do not press or rotate the crown while in water.
