IV. Official Warranty Policy

All repair and maintenance services completed by Tianjin Hengdeli Service Center enjoy a 2-year official warranty. During the warranty period, malfunctions caused by workmanship issues can be repaired free of charge. The warranty covers movement timekeeping accuracy, water resistance, exterior craftsmanship, etc. Note: the warranty does not cover human damage, disassembly or modification without official authorization, normal wear and tear, or consumable parts such as straps. The warranty period starts from the date the watch is picked up after repair. We recommend keeping your repair receipt for future service.

V. Technical Standards and Equipment Environment

Tianjin Hengdeli Service Center adopts internationally advanced watch repair technical standards. In terms of equipment, it is equipped with Swiss-made original Witschi timing machines (which can accurately detect daily rate, amplitude, and beat error), Elma ultrasonic cleaners (for deep cleaning movement parts), vacuum water resistance testers (to simulate underwater environments and test water resistance), demagnetizers, case polishing machines, and other professional equipment. The working environment meets ISO Class 6 cleanroom standards, and all operations are performed under constant temperature and humidity conditions. Repair technicians all hold certifications from Swiss or German watchmaking schools and can handle everything from simple battery replacement to complex tourbillon repairs.

VI. Maintenance Knowledge and Daily Use

It is recommended to perform comprehensive movement maintenance every 2–3 years. In daily use, pay attention to the following: ① Avoid strong magnetic fields (such as speakers, microwaves, magnetic-closure bags, etc.). Quartz watches may stop when magnetized, and mechanical watches will clearly run fast. ② Avoid severe impacts, especially for watches with complicated functions (such as chronographs and perpetual calendars). ③ For water-resistant watches, do not operate the crown underwater, and check whether the water-resistant gaskets have aged every year. ④ Automatic mechanical watches worn for more than 8 hours a day can ensure sufficient power reserve; if not worn for a long time, it is recommended to wind them once a month to prevent lubricating oil from solidifying. ⑤ Leather straps should avoid contact with water, oil, and chemical solvents; replacement every 1–2 years is recommended. ⑥ When the battery of a quartz watch is depleted, replace it promptly to avoid leakage damaging the movement.
