The Xiaomi Watch S4 41mm strap is made from calf leather and undergoes multiple tanning processes.
Please note the following for daily use:
1. Regular bending (especially around the clasp area) will gradually create usage marks.
2. Contact with sweat or cosmetics will accelerate texture changes.
3. It is recommended to regularly apply specialized leather care oil (about once a month).
4. Avoid prolonged exposure to direct sunlight or liquids.
5. When not in use, place the strap flat for storage.
