Maintenance

Cleaning
- For metal bracelets and water-resistant cases, use a toothbrush and soapy water, then rinse with clear water and dry with a soft cloth.
- For textile straps, clean gently with a damp cloth and mild soap. Avoid excessive moisture.
- Avoid using chemical cleaning products as they may damage the watch materials.
Water Resistance
Your Tissot Supersport Chrono is water-resistant to 10 bar (100 meters / 330 feet), suitable for swimming and showering. However, it is crucial to ensure the crown and pushers are fully pushed in before any contact with water. Do not operate the crown or pushers while the watch is wet or submerged.
Battery Replacement
When the battery is low, the seconds hand may jump every four seconds (End-of-Life indicator). It is recommended to have the battery replaced by an authorized Tissot service center to ensure proper sealing and functionality.

Troubleshooting
If you encounter issues with your watch, refer to the following common problems and solutions:
- Watch not running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Chronograph hands not resetting to zero: This may require a chronograph reset procedure. Consult an authorized service center if the issue persists after attempting a manual reset (refer to operating instructions).
- Condensation under the crystal: This indicates a loss of water resistance. Immediately take the watch to an authorized service center to prevent further damage.
