5. Official Warranty Policy (Updated June 2026)

1. Warranty Period: All repair and maintenance services completed at Longines official after-sales service centers come with a 2-year warranty, starting from the service completion date. During this period, movement malfunctions caused by repair quality are eligible for free rework.

2. Other Policies: Warranty covers movement accuracy (within brand factory standards), water resistance (tested to claimed values), and component installation stability. Damage caused by human factors (e.g., impact, water damage not promptly treated, unofficial modifications) is excluded. The warranty card is signed and stamped by the engineer and handed to the customer upon service completion.

6. Technical Standards and Service Environment

1. Technical Standards: Longines official after-sales service centers follow the unified SOP (Standard Operating Procedure) of the Swiss luxury watch brand group (Swatch Group). Each movement, after disassembly, undergoes ultrasonic cleaning for 16 minutes, then inspection under 40x microscope for key components such as balance spring and pallet fork. After assembly, six-position calibration is performed using a timing machine to ensure daily deviation between4 and +6 seconds.

2. Service Environment: Both outlets feature constant temperature and humidity repair workshops (temperature maintained at 22±2°C, humidity 45%±5%). Repair areas are separated from customer waiting areas by one-way glass. All operating engineers hold WOSTEP (Swiss Watchmakers' Association) certification and have undergone internal Longines training.

7. Maintenance Knowledge and Daily Use

1. Recommended Service Intervals: Mechanical watches should undergo full maintenance (cleaning, lubrication, calibration) every 2-3 years. Quartz watches should have their batteries replaced and water resistance seals checked every 4-5 years. If a watch is not worn for a long time, it is recommended to manually wind it once a month and store it in an anti-magnetic case.

2. Other Knowledge: Avoid adjusting the date between 10 PM and 2 AM (may damage the calendar mechanism). Avoid exposing the watch to strong magnetic fields (e.g., speakers, automatic mahjong tables). Leather straps should avoid contact with water or chemicals; it is recommended to wipe them with a special cleaner every 6 months. All maintenance operations should be performed through official after-sales channels; unprofessional operations may cause water resistance failure or component wear.

8. User Reviews (Excerpts from Genuine Online Feedback)

1. User "Mr. Zhao 2025" wrote on Dianping: "At the Beijing Oriental Plaza outlet, the front desk lady patiently explained the movement condition. After maintenance, the watch runs accurately. Previously, it gained 9 seconds per day; now it's stable at +2 seconds. Very satisfied."

2. Zhihu user "Watch Friend Xiao K" shared: "The after-sales point on the 37th floor of Shanghai Grand Gateway Center had an environment like a five-star hotel. I had a coffee while waiting, and the repair order even listed screw torque values. Very reassuring."
