- G-SHOCK Logo: Prominently displayed at the top of the watch face.
- SHOCK RESIST: Indicated at the bottom of the watch face, highlighting the watch's durability.
- WR200M: Water Resistance up to 200 meters, printed on the dial.
- ANTIMAGNETIC: Indication of magnetic resistance on the dial.
Button Functions:
- H-SET Button (Top Left): Used for hand setting and adjustment.
- MODE Button (Bottom Left): Cycles through different modes of the digital display (e.g., Date, Time, Alarm, Stopwatch, Dual Time).
- ADJUST Button (Top Right): Used for adjusting settings within a selected mode.
- LIGHT Button (Bottom Right): Activates the electro-luminescent backlight for the digital display, improving visibility in dark conditions.
3. Setup
Initial Battery Installation:
The watch comes with a Lithium Metal battery included. No initial battery installation is typically required for new watches. If the display is dim or functions are not responding, the battery may need replacement. It is recommended to have battery replacement performed by a qualified watch technician.
Setting Time and Date:
To set the time and date, use the MODE and ADJUST buttons. The digital display can be toggled between showing the date and the current time by pressing the MODE button. For detailed instructions on setting the analog hands and digital display, refer to the official user guide.
4. Operating Instructions
Timekeeping:
The watch features a Quartz movement, providing an accuracy of approximately ±15 seconds per month. It includes an auto-calendar function.
Alarm Function:
The watch is equipped with a daily alarm. Access the alarm setting mode by pressing the MODE button until 'ALM' appears on the digital display. Use the ADJUST button to set the alarm time.
Stopwatch:
A 1/100-second stopwatch function is integrated. To use the stopwatch, navigate to the 'STW' mode using the MODE button. The ADJUST button typically starts and stops the timer, while the H-SET button may reset it.
Dual Time:
The dual time feature allows simultaneous display of two different time zones. One time zone is shown on the analog display, and another can be set and viewed on the digital display ('DUAL' mode). This is useful for travelers or those communicating across time zones.
Backlight:
Press the LIGHT button to illuminate the digital display with an electro-luminescent backlight. The analog hands are coated with Neobrite, providing luminescence after exposure to light, for easy reading in the dark.
5. Maintenance
Cleaning:
Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For stubborn grime, a slightly damp cloth can be used, followed by drying. Avoid harsh chemicals or abrasive cleaners.
Water Resistance:
While the watch is water-resistant to 200 meters, it is advisable to rinse it with fresh water after exposure to saltwater to prevent corrosion. Avoid operating buttons underwater to maintain water resistance.
Battery Replacement:
The battery life is approximately 3 years. When the display becomes dim or functions are erratic, it may be time for a battery change. For optimal performance and to maintain water resistance, battery replacement should be performed by an authorized Casio service center.
6. Troubleshooting
- Watch Not Keeping Time: Check if the battery needs replacement. Ensure the watch is not exposed to extreme temperatures or strong magnetic fields.
- Digital Display is Blank/Dim: This typically indicates a low battery. Replace the battery.
- Buttons Not Responding: Ensure the watch is not in a locked mode (if applicable, though not specified for this model). If issues persist, a reset may be required (refer to the full user guide for reset procedures), or professional service might be needed.
- Water Inside Watch: If condensation or water appears inside the watch, cease use immediately and take it to an authorized service center. This indicates a breach in water resistance.
