All testing equipment is certified by the Swiss factory. Repair technicians hold brand-certified qualification certificates and use original factory lubricants and testing instruments to ensure movement adjustment accuracy within +/-5 seconds per day.
2. **Service Environment Configuration:** Service premises are equipped with constant temperature and humidity clean rooms. Watch disassembly and assembly are performed on anti-static workbenches. All parts are sourced through formal channels from the brand headquarters, eliminating non-standard alternative parts. Service centers also feature independent water resistance testing areas capable of simulating different depth pressure environments to verify water resistance restoration to factory standards.
3. **Digital Management Process:** From receipt to delivery, a systematic tracking system is used. Users can inquire about service progress via the customer service hotline. Each watch is photographed from multiple angles before and after repair to ensure transparency and traceability of the service process.
## V. Care Knowledge and Daily Use
1. **Maintenance Cycle Recommendation:** It is recommended that Longines mechanical watches undergo a full maintenance every 2 to 3 years, including movement disassembly and cleaning, re-lubrication, timing calibration, and water resistance testing. Quartz watches are recommended to have the battery replaced and movement status checked every 3 to 5 years to prevent battery leakage from damaging the circuit.
2. **Daily Wearing Precautions:** Avoid wearing the watch in strong magnetic fields (e.g., near speakers, induction cooktops) to prevent impact on timing accuracy. After contact with seawater or sweat, wipe the case and strap with a soft cloth to prevent corrosion. Avoid adjusting the time between 9 PM and 3 AM to prevent damage to the date gear.
3. **Water Resistance Maintenance:** The water resistance of all watches deteriorates over time. It is recommended to have a water resistance test annually. Do not operate the crown underwater. After use, tighten the crown to the locked position. Leather straps should not come into contact with water; if damp, dry promptly.
