V. Maintenance 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, and calibration. For quartz watches, if timing abnormalities occur, it is recommended to replace the battery immediately and check the circuit.

2. Daily Wearing Precautions

Avoid contact with strong magnetic fields, such as MRI equipment and speaker magnets. After swimming, rinse the case with clean water and dry it. It is recommended to gently wipe leather straps with a soft cloth monthly and avoid contact with chemical solvents. When not worn for a long time, mechanical watches should be wound once a month to maintain lubrication.

3. Water Resistance Check

Water resistance should be checked once a year, especially after replacing the battery or crystal. If fog appears on the crystal, stop using immediately and contact customer service.
