Maintenance
Cleaning Your Watch
To maintain the appearance and functionality of your watch, regularly clean the resin case and strap with a soft, damp cloth.

Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish.
Battery Replacement
When the battery needs replacement, it is recommended to have it done by a qualified watch technician. This ensures proper sealing for water resistance and prevents damage to the internal components.
Troubleshooting
If you encounter any issues with your Armitron Sport watch, consider the following common solutions:
- Display is blank or dim: The battery may be depleted. Replace the battery as described in the Maintenance section.
- Time is inaccurate: Re-set the time following the Initial Setup instructions. If the issue persists, the battery may be low or the watch may require servicing.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable) or that no debris is obstructing the buttons. If the issue continues, professional inspection may be needed.
- Water inside the watch: If condensation or water appears inside the watch, immediately take it to a qualified technician. This indicates a breach in the water resistance seal.
