Setting the Time Manually on a G Shock Watch

To manually adjust the time on your G Shock watch, begin by entering the time-setting mode. This is typically done by pressing and holding the “Adjust” button (usually located at the top-left of the watch face) until the seconds digits start flashing. This flashing indicates that you are now in the time-setting mode and ready to make adjustments.

Once in time-setting mode, you can cycle through the various settings you want to change, such as seconds, hours, minutes, year, month, and day. Use the “Mode” button (generally at the bottom-left) to move between these fields. Each press will shift the flashing indicator to the next field.

To increase or decrease the value of the selected field, use the “Forward” and “Reverse” buttons (often the top-right and bottom-right buttons respectively). Depending on the model, some watches may only allow incrementing values, in which case you will have to cycle through the numbers to reach the desired setting.

After adjusting all the necessary fields, press the “Adjust” button again to exit the time-setting mode. Your G Shock watch will now display the updated time.

Using Atomic Timekeeping or Radio Signal for Automatic Time Adjustment

Many modern G Shock watches feature Multi-Band 6 Atomic Timekeeping, which allows the watch to synchronize automatically with atomic clocks via radio signals. This feature ensures that your watch maintains accurate time without manual adjustments.

To enable or check atomic timekeeping:

  • Make sure your watch is in an area with good reception for radio signals.
  • Place the watch near a window at night for optimal signal reception.
  • Some models have a manual receive function, activated by holding a specific button (often the “Receive” or “Signal” button) to initiate time calibration.

The watch will automatically adjust the time based on the received atomic signals, correcting any deviation from the accurate time standard. If your watch does not receive the signal, it will attempt to resynchronize at preset times, often during the night.

Adjusting Time on Specific G Shock Models

Different G Shock models have slightly varying button configurations and procedures for time adjustment. Below is a reference table showing common button layouts and corresponding functions for popular models:

G Shock Model Adjust Button Mode Button Forward Button Reverse Button Time-Setting Entry

Always consult your specific model’s user manual to confirm button functions, as some models include additional features such as world time, daylight saving time (DST) toggling, and 12/24-hour format switching within the time-setting mode.

Adjusting Daylight Saving Time and 12/24-Hour Format

Most G Shock watches allow you to toggle daylight saving time (DST) and switch between 12-hour and 24-hour time formats while in the time-setting mode. To adjust these settings:

  • Enter the time-setting mode by pressing and holding the “Adjust” button.
  • Use the “Mode” button to navigate to the DST setting or 12/24-hour format option.
  • Toggle DST on or off by pressing the “Forward” or “Reverse” button.
  • Switch between 12-hour and 24-hour formats similarly by using the same buttons.

Activating DST typically adds one hour to the displayed time, which is useful during summer months in certain regions. The 12-hour format shows AM/PM indicators, while the 24-hour format displays time in military time.

Synchronizing Analog Hands with Digital Time

Some G Shock models feature both analog and digital time displays. Occasionally, the analog hands may fall out of sync with the digital time, especially after a battery change or exposure to magnetic fields.

To manually adjust the analog hands:

  • Enter the hand-setting mode, often by holding down the “Adjust” button for a longer duration or pressing a specific button combination.
