Common timing faults include running slow, intermittent stopping, sudden halt, running fast and irregular stoppage. For watches worn less than 2 years, the problem may be caused by bumps. Otherwise, it may result from low amplitude of the balance wheel, jammed gears or loose small parts. For watches used over 2 years, the issue is usually caused by lack of maintenance. Dried sludge inside the movement hinders the operation of components. Magnetization is another common cause. Professional inspection is required to confirm the exact fault. We suggest bringing your watch to Hengdeli Repair Center immediately. Delayed maintenance will lead to part abrasion and higher repair costs.

Water or dust entering the watch is generally caused by loose crystal, aging waterproof gaskets, loose case back, gaps from impact, or water intrusion when pulling out the crown. Such problems must be dealt with promptly. Long-term erosion from moisture and abrasion from dust will damage the movement, raise repair costs, shorten service life, and even cause permanent damage to the movement. Please send your watch to Hengdeli Repair Center for inspection right away once this problem occurs.

Frequent water fogging and long-term lack of maintenance will gradually lead to rust inside the movement. Untreated rust will corrode movement components and eventually stop the watch completely. To avoid expensive repairs, we recommend rust removal, cleaning and re-oiling at our repair center. Basic movement maintenance includes: ① Inspect movement functions and fully disassemble the movement; ② Clean, lubricate, assemble and adjust precision according to the rust condition; ③ Replace aged waterproof gaskets and damaged movement components as needed.

Minor scratches: Scratches are unavoidable during daily wear. Shallow scratches that do not touch hard objects can be easily removed. Simply apply toothpaste with a soft cloth to restore the luster of the case or bracelet. Deep scratches caused by sharp objects require professional polishing. Watch polishing requires high professional skills. We recommend choosing a regular professional watch repair center to achieve perfect refinishing results.

A watch is a precision timing device with tiny internal components. Severe shock and collision will cause internal faults, such as cracked crystal, dented case, broken crown, loose or fallen hands, faded luminous parts, deformed dial and damaged movement parts. If you lack professional experience, do not replace parts by yourself. Please send your watch to the professional Hengdeli Repair Center for inspection. Improper operation will cause inaccurate timekeeping and other faults.

Watch exterior maintenance covers two parts: 1. Case and bracelet: Avoid friction and collision with objects of equal or higher hardness. Regular cleaning is essential. Seawater, salt water, perfume, shampoo, nail polish, nail polish remover and chemical cosmetics will corrode gold plating, metal surfaces and leather straps. 2. Watch crystal: Three main materials are acrylic, mineral glass and sapphire crystal. Acrylic is scratch-prone but impact-resistant. Sapphire crystal is highly wear-resistant yet brittle against heavy shock. Mineral glass sits between the two. Even scratch-resistant sapphire crystal can be scratched by diamond, whetstone, sandpaper, nail files, granite and concrete walls.

Long-term lack of maintenance will cause lubricant to dry up and form sludge, which leads to dry friction and component damage. Replacing damaged movement parts will cost much more. We recommend full movement maintenance every 2 to 3 years to guarantee accurate timekeeping and extend the watch service life.

Polishing can restore your Hengdeli watch to brand-new condition. Our watchmakers will fully disassemble the watch and polish every component. This delicate operation removes a thin layer of metal, so polishing should only be carried out when necessary. Case polishing: Manual polishing to restore the original luster; white gold watches will receive rhodium plating for extra shine. Bracelet polishing: Metal straps and clasps are hand polished, and white gold pieces get rhodium finishing. Case and metal bracelets have fixed cleaning cycles to thoroughly remove residual dirt. Cleaning is a necessary pre-polishing step to avoid scratches caused by particles. Polishing is only performed upon customer request. Polishing work includes light trimming and multiple techniques: traditional hand polishing relying on rich experience, exquisite craftsmanship and precise operation. Other techniques include satin finishing, laser treatment and diamond polishing for mirror effects. Note that a watch can only be polished a limited number of times throughout its service life.

Dirty metal bracelets can be cleaned with a soft toothbrush and toothpaste. Rinse, wipe with flannel and blow dry with a hair dryer. Gold watches may discolor due to oxidation. We recommend professional treatment at Hengdeli Repair Center. For gem-set watches, check diamond tightness regularly. Do not clean gem watches yourself. Full maintenance is recommended every 2 to 3 years, including waterproof component replacement, timing test, power consumption test, movement cleaning and exterior care.

Complete maintenance covers nearly all watch service steps: disassembly, cleaning, lubrication, testing, as well as polishing and refinishing based on watch condition. This service strictly tests the skill of watchmakers. Technicians need to inspect the whole watch first, confirm detailed maintenance steps and carry out each operation one by one. Only regular repair centers are qualified for this work. Many watches suffer permanent damage due to improper operation and incorrect polishing techniques. What does the full maintenance service at Hengdeli Repair Center include? 1. Fully disassemble, clean, lubricate, reassemble, calibrate and test all movement functions; 2. Repair or replace all worn or faulty movement components; 3. Replace the following parts: watch crystal, crown, pushers, sealing gaskets and batteries for quartz watches (standard parts only, excluding special-shaped mineral glass and sapphire crystal); 4. Restore water resistance for waterproof models; 5. Refinish case and bracelet (two-tone, gold-plated and PVD-coated cases and bracelets will only be cleaned without polishing).
