2. Pricing Standards (the prices below are reference prices for basic movement maintenance of entry-level models; all prices vary with promotions, and repair prices differ according to the extent of damage. Because watch grade and model, complexity, craftsmanship, part materials, damage conditions and service items all differ, it is impossible to give a uniform repair and maintenance quotation for every watch in every situation. A detailed quote requires you to provide customer service with the specific information about your watch, its current condition and the service items required, after which an accurate quotation can be given.)

III. Official Warranty Policy

1. Warranty Period

Hengdeli official after-sales service provides a 2-year warranty, counted from the date the repaired or serviced watch is delivered. During the warranty period, problems caused by non-human factors — such as movement timekeeping deviation or natural part wear — qualify for free repair or replacement.

2. Warranty Coverage

① Movement parts: including mainspring, balance wheel, escapement system and other major movement components.

② Water resistance: after repair, the water-resistance rating is restored to factory standard; water ingress caused by aging gaskets during the warranty period is handled free of charge.

③ Exterior parts: original replacement crystals, crowns, pushers and so on are replaced free of charge during the warranty period if damaged by non-human causes.

④ Battery: covered for one year after replacement; if natural battery leakage affects the movement, it is repaired free of charge.

3. Warranty Exclusions

① Damage caused by human impact, dropping, water ingress (use not in accordance with water-resistance standards) or improper operation.

② Self-disassembly, repair or modification through non-official channels.

③ Abnormalities caused by environmental factors (magnetic fields, temperature, corrosive gases).

④ Normal wear of straps, clasps and similar parts, as well as exterior scratches, are not covered by the warranty.

IV. Technical Standards and Equipment Environment

1. Testing and Repair Equipment

Hengdeli after-sales centers are equipped with precision instruments imported from Switzerland, including:

① Witschi Q200 timing machine: used to measure key indicators such as daily rate, amplitude and beat error, with precision to 0.1 seconds.

② Vacuum water-resistance tester: simulates water pressure environments from 50 meters to 300 meters in depth to check case sealing.

③ Ultrasonic cleaning machine: uses a multi-tank heated cleaning system together with dedicated cleaning solutions to remove oil and impurities.

④ Microscope inspection station: magnification of 10–40x, used to examine part wear, scratches and assembly precision.

⑤ Mechanical amplitude tester: calibrates the energy transmission efficiency of the escapement mechanism to ensure stable timekeeping.

2. Environmental Standards

The repair workshop is a constant-temperature, constant-humidity, dust-free environment, with temperature controlled at 22±2°C and humidity at 45%–55%. It uses a HEPA filtration system, and airborne particulate levels are below the ISO Class 8 standard. All workstations are equipped with antistatic wrist straps and metal grounding to prevent static electricity from damaging sensitive movement components.

V. Care Knowledge and Daily Use

1. Recommended Maintenance Intervals

Mechanical watches are advised to undergo basic maintenance every 2–3 years, including movement cleaning, lubrication and water-resistance testing. Quartz watches are advised to have the battery replaced and gaskets checked every 4–5 years. If a watch has not been worn for a long time, a timekeeping test and exterior inspection should be performed before it is used again. For watches frequently exposed to sweat, seawater or chemicals, the maintenance interval should be shortened to 1.5–2 years.

2. Daily Use Precautions

① Avoid strong magnetic environments (such as speakers, refrigerator doors and magnetic-closure bags) to prevent the movement from becoming magnetized and keeping inaccurate time.

② Wind the watch at a fixed time each evening; it is recommended to wind it fully before wearing it in the morning to ensure sufficient power reserve.

③ Before adjusting the time on a dive watch, confirm that the crown is fully screwed down, and avoid operating it underwater.

④ Leather straps should avoid prolonged contact with water and direct sunlight; switching to a metal or rubber strap in summer is recommended.

⑤ Regularly wipe the case and crystal with a soft cloth to remove sweat stains and dust and keep the exterior clean.

3. Simple Troubleshooting of Common Faults

① Running fast/slow: possibly magnetized; take it to after-sales service for demagnetization (a free service).

② Stopped: first check whether it is insufficiently wound; wind it manually 20–30 turns and observe. If it still does not run, the hairspring may be sticking or the gears jammed, and it must be sent for repair.

③ Fogging under the crystal: this indicates aging water-resistance gaskets; stop using the watch immediately and send it for repair to prevent the movement from rusting.

④ Abnormal date change: avoid adjusting the date between 9 p.m. and 3 a.m., as the gears are meshing during this period and adjustment can easily cause damage.
