4. Important note: because of differences in watch grade and model, complexity, craftsmanship, accessory materials, damage condition and service items, maintenance and repair quotes for each watch cannot be uniform. A detailed quote requires the customer to provide the customer service team with specific watch information, the watch's current condition and the requested service items.

IV. Official warranty policy

All maintenance services completed through official Hengdeli channels enjoy a 2-year official warranty. During the warranty period, Hengdeli provides free handling for repair quality or parts issues caused by non-human factors. The warranty covers movement repair, replacement parts, case treatment, etc., subject to the service document. Customers should keep service vouchers to enjoy warranty rights.

V. Technical standards and equipment environment

Hengdeli's service centers nationwide are equipped with professional equipment, including Swiss-imported Witschi timing machines, Elma ultrasonic cleaners, Bergeon watch-opening tools, Lepsi water resistance testers and professional vacuum coating equipment. All repair technicians have passed Hengdeli system training and assessment and strictly follow brand technical standards. Repair workshops use constant-temperature, constant-humidity clean environments, with temperature controlled at 22±2°C and humidity below 45%, ensuring movement adjustment precision. Equipment is calibrated regularly, with certification reports issued by third-party metrology institutions, guaranteeing service craftsmanship requirements.

VI. Care knowledge and daily use

The recommended watch maintenance interval is 2 to 3 years. If a mechanical watch is not worn for a long time, manually wind it once a month to keep the movement lubricating oil evenly distributed. Avoid placing the watch near strong magnetic fields (such as speakers, magnetic clasps). For daily cleaning, wipe with a soft cloth. Water-resistant watches should have their gaskets checked regularly, and the waterproof rubber ring should be replaced once a year. For quartz watches, water resistance testing is recommended when changing the battery. Strap care: metal straps can be cleaned with warm water and a small amount of neutral detergent; leather straps should avoid contact with water and chemicals. All maintenance suggestions are based on official Hengdeli technical support; customers can call 400-878-6612 for personalized guidance.
