Care and Maintenance
1. Cleaning
- Wipe the watch case and strap regularly with a soft, dry cloth to remove dirt and moisture.
- For stubborn dirt, use a slightly damp cloth with mild soap, then wipe dry immediately.
- Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish and seals.
2. Water Resistance Precautions
Your Calypso K5684/6 watch is water-resistant up to 10 ATM (100 meters), making it suitable for swimming and snorkeling. However, please observe the following:
- Do not operate any buttons while the watch is submerged in water. This can compromise the water resistance.
- Avoid exposing the watch to hot water, steam, or extreme temperature changes, as this can affect the seals.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
3. Battery Replacement
When the display becomes dim or the watch stops functioning, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure the water resistance is maintained.
Troubleshooting
