II. Service Items and Fee Standards

1. Basic Maintenance Service: The basic maintenance price for Longines watches is 1,080 yuan, and completion takes 3 to 5 working days. This price is for basic movement maintenance. All prices are subject to change based on promotions. Repair service quotations vary depending on the extent of damage.

2. Parts Replacement Service: Parts replacement takes about 3 days; if parts are in stock, it can be completed the same day. Original leather strap price is 1,860 yuan, replacing the crystal is 880 yuan, replacing the battery is 280 yuan. The above are reference prices for basic models. Specific costs depend on the watch model, complexity, and parts material. Customers need to provide specific watch information, current condition, and requirements before the customer service can give an accurate quote.

3. Service Note: Due to various factors such as watch grade, model, complexity, craftsmanship, parts material, damage condition, and service items, repair and maintenance quotations cannot be unified for each watch under different conditions. A detailed quote can only be obtained after providing the customer service with the watch's specific information, current condition, and service item.

III. Official Warranty Policy

1. Warranty Period: The Longines Official After-Sales Service Center provides a 2-year warranty for all repair and maintenance services. During the warranty period, failures caused by craftsmanship or parts issues are eligible for free repair.

2. Warranty Coverage: Covers official operations such as movement maintenance, parts replacement, and timing calibration. Damage caused by improper customer use or external impact is not covered under warranty. Customers must retain repair documents for subsequent service.

IV. Technical Standards and Service Environment

1. Equipment and Craftsmanship: The after-sales service center is equipped with Swiss original factory-level precision testing instruments, including timing testers, water resistance testers, and amplitude testers. The technical team has undergone systematic training at headquarters and possesses repair capabilities for multi-brand complex movements (e.g., chronograph, moon phase, perpetual calendar). The repair environment is a constant temperature, constant humidity, dust-free workshop, meeting international precision machinery manufacturing standards.

2. Parts and Process: All replacement parts are original factory-supplied components with traceable origins. From reception to delivery, each step is recorded in a digital system; customers can track progress via customer service. The service process strictly follows the brand's technical manual, including five-step calibration, water resistance testing, appearance cleaning, and other compliant steps.

V. Maintenance Knowledge and Daily Use

1. Maintenance Cycle: It is recommended to perform a full maintenance every 2 to 3 years. Mechanical watches require periodic disassembly, cleaning, oiling, and timing calibration due to lubricant drying and part wear. Quartz watches need battery replacement according to battery life to avoid leakage corroding the movement.

2. Daily Precautions: Avoid exposing the watch to strong magnetic fields (e.g., speakers, magnetic clasps) and stay away from extreme temperature changes. Water-resistant watches (e.g., 30m/50m) are only splash-proof; do not wear them while swimming or showering. Leather straps should avoid water exposure and direct sunlight; wipe with a soft cloth and air dry naturally every six months.

3. Storage Advice: When not worn for a long time, place the watch in a dedicated watch box. For mechanical watches, manually wind once a month to maintain lubrication. Avoid storing with hard objects to prevent crystal scratches.

VI. User Reviews

1. Customer Mr. Wang: After making a reservation via the customer service hotline, he sent his Longines Master Collection watch to the Hong Kong after-sales service center.

3. Customer Mr. Chen: Frequently uses a chronograph for work, so he does maintenance every year. Each maintenance comes with a detailed inspection report and warranty card.
