  • Forward Button: Increases the value of the flashing setting.
  • Reverse Button: Decreases the value, if available on your model.

Each press of the Mode button moves you to the next setting. Adjust the values accordingly until the correct time and date are displayed.

Using the Table for Button Functions

Button Name Typical Location Function in Time Setting Mode

Mode Bottom-left Cycle through time and date settings
Forward (Start/Stop) Top-right Increase value of selected setting
Reverse (Split/Reset) Bottom-right Decrease value of selected setting (on some models)

Setting the Time in Different Formats

G-Shock watches typically allow you to toggle between 12-hour and 24-hour time formats. This setting is usually adjusted within the time setting mode:

  • When the hour digits are flashing, press the Forward or Reverse button to switch between AM/PM (12-hour) and 24-hour formats.
  • Confirm the selection by pressing the Mode button to proceed to the next setting.

Similarly, you can adjust the date format (month-day or day-month) by cycling through the date settings and using the Forward/Reverse buttons to choose the preferred format.

Synchronizing Time with Radio Signals or GPS

Certain G-Shock models feature Multi-Band 6 technology or GPS timekeeping, which automatically synchronize the watch’s time with atomic clocks via radio signals or satellite data. To enable or manually trigger synchronization:

  • Access the timekeeping mode on your watch.
  • Hold down the designated button (often the Forward or Adjust button) until the watch indicates it is searching for signals.
  • Ensure you are in an open area with a clear view of the sky to improve reception.
  • The watch will update the time automatically once synchronization is successful.

If synchronization fails, the watch will revert to the previously set time. Manual adjustments will then be necessary.

Tips for Accurate Time Setting

  • Always set the seconds to zero when adjusting the time for precise synchronization.
  • When setting the date, ensure the watch is set to the correct AM or PM period to avoid errors in the calendar.
  • If your watch has a daylight saving time (DST) setting, enable or disable it according to your local time zone to maintain accuracy.
  • Refer to the specific user manual for your G-Shock model, as some variations may exist in button functions and features.

Common Troubleshooting Issues

  • Watch won’t enter time setting mode: Ensure you are pressing and holding the Adjust button long enough (usually about 3 seconds). If the watch has a lock function, disable it first.
  • Buttons not responding: Check if the watch is in a different mode such as Stopwatch or Alarm mode. Press the Mode button until you return to the main timekeeping screen.
  • Time resets after battery replacement: Some models require you to reset the time manually after changing the battery, especially those without radio or GPS synchronization.
  • Incorrect time after synchronization: Confirm that your location supports radio signal reception or GPS coverage, and try synchronizing the watch in an open area.

By following these detailed steps and tips, you can ensure your G-Shock watch displays the correct time and date consistently and reliably.

Setting the Time on Your G-Shock Watch

Setting the time on a G-Shock watch involves using the watch’s buttons to enter a time-setting mode and adjust the hours, minutes, and other relevant settings. Although specific steps can vary slightly depending on the model, the general procedure is consistent across most G-Shock watches.
