Setting the Time and Date

1. Enter Timekeeping Mode: Ensure the watch is in the standard Timekeeping Mode. If not, press the MODE button repeatedly until the current time is displayed.
2. Access Setting Screen: Press and hold the ADJUST button (usually top-left) until the city code starts to flash on the digital display. This indicates the setting mode.
3. Select Settings: Use the MODE button to cycle through the settings: City Code, DST (Daylight Saving Time), 12/24-hour format, Seconds, Hour, Minute, Year, Month, Day.
4. Adjust Values: Use the SEARCH button (usually top-right) or RESET button (usually bottom-right) to increase or decrease the flashing value.
5. Synchronize Analog Hands: After setting the digital time, the analog hands may need to be adjusted. In the setting mode, navigate to the hand alignment setting (refer to the full digital manual for exact steps, often indicated by "H-SET" or similar). Use the adjustment buttons to align the analog hands with the digital time.
6. Exit Setting Mode: Press the ADJUST button once more to exit the setting mode and save your changes.

Battery Information

The GA-010-2A is equipped with a long-life Lithium Metal battery, designed to provide approximately 10 years of operation under normal use. The watch requires one (1) Lithium Metal battery. When the battery power is low, the display may dim or functions may become unreliable. Battery replacement should be performed by a qualified Casio service center to maintain water resistance and ensure proper function.

Maintenance and Care

Water Resistance

Your G-Shock GA-010-2A is water-resistant up to 200 meters (20 BAR). This means it is suitable for showering, swimming, and recreational scuba diving. However, avoid operating buttons while the watch is submerged in water or wet, as this can compromise the water resistance. After exposure to saltwater, rinse the watch thoroughly with fresh water and wipe it dry.

Cleaning

To clean the watch, wipe it with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent, then wipe dry. Avoid using volatile agents like thinner, gasoline, alcohol, or chemical sprays, as they can damage the resin components.

Battery Replacement

While the battery has a 10-year lifespan, eventual replacement will be necessary. Due to the watch's intricate design and water resistance sealing, it is highly recommended to have battery replacement performed by an authorized Casio service center. Attempting to replace the battery yourself may void the warranty and compromise the watch's water resistance.

Troubleshooting

• Analog Hands Do Not Match Digital Time: This can occur due to strong magnetic fields or impacts. Refer to the "Setting the Time and Date" section for instructions on manually aligning the analog hands. If the issue persists after alignment, contact customer support.
• Digital Display is Blank or Dim: The battery may be low. While the watch has a 10-year battery, extreme temperatures or heavy use of the LED light can affect its lifespan. Consider professional battery replacement.
• Buttons Are Unresponsive: Ensure the watch is not in a locked mode (if applicable, though less common on this model). If buttons remain unresponsive, a reset may be required (consult the full manual or customer support), or there may be an internal malfunction.
• Water Inside the Watch: If you notice condensation or water inside the watch, immediately stop using it and take it to an authorized service center. This indicates a compromised water seal.
