Setting the Time on Analog-Digital G-Shock Models

Adjusting the time on an analog-digital G-Shock watch involves synchronizing both the analog hands and the digital display to ensure accurate timekeeping. This process can vary slightly depending on the specific model, but the general steps remain consistent.

Start by entering the time adjustment mode, typically achieved by pressing and holding the “Adjust” button for a few seconds until the digital time starts flashing. This indicates that the watch is ready for time setting.

Use the “Mode” button to cycle through different settings such as seconds, hours, minutes, year, month, and day. When the desired setting is flashing, adjust the value using the “Forward” or “Reverse” buttons. For some models, these buttons are labeled as “+” and “–” or may be positioned as buttons A, B, C, or D.

Once the digital time is set, synchronize the analog hands if they do not automatically align. This typically requires entering the hand-setting mode by pressing and holding the “Adjust” button again. Use the “Forward” and “Reverse” buttons to move the hour and minute hands to the correct position. This step is crucial for models where the analog hands and digital time can drift out of sync.

Understanding Time Format and Daylight Saving Settings

Many G-Shock watches allow users to switch between 12-hour and 24-hour time formats, as well as enable or disable daylight saving time (DST) adjustments. These features provide flexibility depending on user preference and regional requirements.

To change the time format, enter the time setting mode and navigate to the hour or time format option. Use the adjustment buttons to toggle between the 12-hour (AM/PM) and 24-hour (military) formats. The display will update accordingly to reflect your choice.

Daylight saving time can typically be turned on or off in a similar manner. Locate the DST setting within the time adjustment mode and toggle it. When DST is enabled, the watch will automatically add one hour to the current time during the designated months.

Button Functions Overview

Each button on a G-Shock watch plays a specific role during time adjustment. Understanding their functions will streamline the setting process.

Top Right Forward / + Increase values or move hands forward
Bottom Right Reverse / – Decrease values or move hands backward

Tips for Accurate Time Adjustment

  • Ensure the watch is not in power-saving mode or low battery, as this can affect the setting process.
  • When adjusting analog hands, move them forward rather than backward to avoid damaging the movement.
  • For watches with multiple time zones, confirm you are adjusting the home time rather than the secondary time zone.
  • Consult the specific model’s manual for features like auto-hand correction, which can realign analog hands automatically.
  • Perform adjustments in a well-lit environment to clearly see the digital display and hand positions.

Using Auto Time Sync Features

Some advanced G-Shock models include automatic time synchronization through radio signals or GPS. When enabled, these watches will periodically update the time to maintain accuracy without manual intervention.

To utilize auto time sync:

  • Ensure the watch is set to the correct time zone.
  • Place the watch near a window during scheduled synchronization times, usually at night.
  • Confirm the auto-sync function is activated in the settings menu.

If synchronization fails, manual adjustment as described earlier can restore correct timekeeping.
