- Avoid Extreme Conditions: Do not expose the watch to strong sunlight for prolonged periods, fire, or strong physical force to prevent damage.
- Chemicals: Keep the watch away from chemicals, solvents, detergents, perfumes, and cosmetics, as these can damage the watch's materials.
- Water Exposure: While waterproof, avoid exposing the watch to hot water, steam, or sudden temperature changes, which can compromise the seals.
- Storage: When not in use, store the watch in a cool, dry place, away from sharp objects to prevent scratches.
5. Troubleshooting
- Display is blank or dim: Ensure the watch receives sufficient light for solar charging. Place it under bright light for several hours.

- Buttons are unresponsive: Check for any debris around the buttons. If the issue persists, a full reset (if available, consult manufacturer for specific instructions) or professional inspection may be required.
