6. Maintenance
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dirt, dust, and sweat. For more stubborn dirt, a slightly damp cloth can be used, followed by thorough drying.
- Water Exposure: While the watch is water-resistant, avoid prolonged exposure to hot water, steam (e.g., in showers or saunas), or harsh chemicals (e.g., detergents, solvents, perfumes) as these can degrade the watch's seals and materials over time.
- Storage: When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures to prevent damage to the display and internal components.
- Battery Replacement: The watch includes a battery. If the display dims significantly or functions become erratic, it may indicate a low battery. It is recommended to have the battery replaced by a professional watch technician to ensure the water resistance is maintained after opening the case.
7. Troubleshooting
- Display is blank or dim:
- Check if the battery needs replacement.
- Ensure the backlight button is not stuck in an 'on' position, which could drain the battery.
- Time is inaccurate:
- Re-set the time following the instructions in Section 2.3.
- If inaccuracy persists after resetting, the battery may be low, or the watch may require servicing.
- Buttons are unresponsive:
- Ensure the watch is not currently submerged in water, as pressing buttons underwater can cause issues.
- Check for any debris or foreign objects obstructing the buttons.
- Water inside the watch:
- Immediately stop using the watch.
- Seek professional repair as soon as possible to prevent further damage to internal components. This indicates a compromised water seal.
