Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For stubborn grime, use a mild soap solution and a soft brush, then rinse thoroughly with fresh water and dry completely. Avoid using chemical cleaners or solvents.
3. Substituição da bateria
The watch is powered by a quartz movement, requiring a specific watch battery. When the battery runs low, the display may dim or functions may become erratic. It is recommended to have the battery replaced by an authorized CASIO service center to ensure proper sealing and water resistance.

Solução de problemas
- Bluetooth Synchronization Issues: If the watch fails to sync with your smartphone, ensure Bluetooth is enabled on both devices and the G-SHOCK Connected app is running. Try restarting both the watch (by removing and reinserting the battery, if accessible, or performing a factory reset if available) and your phone. Re-pair the devices if necessary.
- Digital Display Readability: The negative digital display on this model can be challenging to read in certain lighting conditions, particularly indoors. Ensure adequate lighting when attempting to read the digital display. The analog hands and luminous markers are designed for primary time reading.
