5.2 Cleaning
Regularly clean your smartwatch and strap to ensure proper hygiene and functionality.
- Wipe the screen and watch body with a soft, damp, lint-free cloth.
- For the strap, use a mild soap solution and rinse thoroughly. Ensure the strap is completely dry before reattaching it to the watch.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the watch's finish.
