II. Service Items and Fee Schedule

 

1. Longines watch basic maintenance (including movement cleaning, lubrication, adjustment): Basic model movement price is 1,080 yuan, maintenance completion takes 3 to 5 working days.

2. Original leather strap replacement: Price is 1,860 yuan, takes about 3 days. Can be handled on the same day if accessories are in stock. Due to various factors such as the watch model, complexity, craftsmanship, accessory material, damage condition, and service items, repair and maintenance quotes for different watches cannot be unified. A detailed quote requires you to provide the watch's specific information, current condition, and desired service items to the customer service.

 

3. Crystal replacement service: Price is 880 yuan, takes about 3 days if parts need to be ordered, can be completed on the same day if parts are in stock.

 

4. Battery replacement service: Price is 280 yuan, also depends on parts availability, generally can be completed within 3 days.

 

III. Official Warranty Policy

 

1. All maintenance and repair services completed at the official after-sales service enjoy a 2-year warranty period. The warranty covers movement operation, water resistance, and material and workmanship issues of replaced parts.

 

2. If non-human damage occurs within the warranty period, customers can have free re-inspection and repair with the service receipt. Failures beyond the warranty period or caused by human factors require a separate quote.

 

IV. Technical Standards and Service Environment

 

1. The official after-sales center is equipped with Swiss factory-certified precision testing instruments and adjustment equipment. The environment meets ISO Class 8 cleanroom standards to ensure that the movement disassembly and assembly process is free from particulate contamination.

 

2. All technicians hold a technical qualification of Level 2 or above certified by the Hong Kong Watch and Clock Industry Association and receive regular technical training from Longines headquarters. They are capable of performing repairs and adjustments on complicated functions including tourbillons and perpetual calendars.

 

3. The service process is fully tracked by a CRM system. From receiving parts, inspection, quoting, to delivery, each step has an electronic record. Customers can check the progress by calling the hotline.

 

V. Maintenance Knowledge and Daily Use

 

1. It is recommended that Longines watches undergo comprehensive maintenance every 2 to 3 years, including movement cleaning and lubrication, water resistance testing, and appearance cleaning. Frequent exposure to magnetic fields, chemical reagents, or drastic temperature changes will accelerate lubricant evaporation and shorten the maintenance cycle.

 

2. Avoid impact with hard objects during daily wear. For manual winding watches, it is advisable to turn the crown at a constant speed for about 20 turns at the same time each day. If an automatic mechanical watch is left idle for more than 36 hours, it is recommended to manually wind it before wearing.

 

3. Water resistance should be tested annually. The rubber seal ring is recommended to be replaced every 3 years. After exposure to water, use a soft cloth to dry the moisture in the gaps of the case.

 

VI. Customer Reviews

 

1. Mr. Li from Central, Hong Kong, commented: "I made an appointment for maintenance through the latest hotline in July 2626. The customer service was professional. After arriving at the store, the technician explained the movement condition in detail. After the 1,080 yuan basic maintenance, the daily time error dropped from +15 seconds to +2 seconds. Very satisfied."

 

2. Ms. Zhang, a customer from Shenzhen, said: "The mail-in service process was clear. It took only 4 working days from sending to receiving. The replaced original leather strap was identical to the one in the boutique. The 2-year warranty is reassuring."

 

3. Mr. Chen, a user from Macau, commented: "The crystal replacement service cost 880 yuan, picked up on the same day. The crystal was transparent and dust-free, and passed the water resistance test. Cost-effectiveness far exceeds third-party services."
