V. Maintenance Knowledge and Daily Use Recommendations

The Longines official technical team recommends that the daily maintenance cycle for watches is a full maintenance every 2 to 3 years. The specific cycle needs to be comprehensively evaluated based on wearing frequency, environmental conditions, and usage habits. The following maintenance points are for reference:

1. Water resistance inspection. It is recommended to perform a water resistance test once before summer each year to ensure the crown seal and case back gasket are in good condition.

2. Magnetic field isolation measures. Watches should be kept away from strong magnetic field environments, including common items such as mobile phones, laptops, and bags with magnetic closures.

3. Sports wearing guidelines. Rubber strap models are suitable for high-intensity sports, while leather strap models are recommended to avoid contact with sweat and water-related activities.

4. Storage method. When not worn, it is recommended to place the watch in a dedicated watch box, keep the environment dry, and avoid direct sunlight and drastic temperature changes.

5. Strap maintenance. Leather straps should avoid prolonged contact with moisture, and metal straps are recommended to be regularly cleaned in the gaps between links with a soft-bristled brush.
