To manually set the time on most G-Shock models, begin by entering the time-setting mode. This process generally involves holding down a specific button until the digits on the display start flashing, indicating that the watch is ready to be adjusted.

Once in time-setting mode, you can adjust the hours, minutes, seconds, and sometimes additional settings such as the date and daylight saving time. Use the designated buttons to increment or decrement the values. Typically, the “Adjust” button initiates the mode, the “Mode” button cycles through settings, and the “Forward” or “Reverse” buttons change the values.

Key points to remember during manual time setting:

  • Ensure you are in the correct time zone before adjusting the time.
  • Confirm whether your watch is set to 12-hour or 24-hour format and adjust accordingly.
  • Some models allow you to toggle between standard and daylight saving time settings.
  • After completing adjustments, press the “Adjust” button again to exit the setting mode and save changes.

Understanding Button Functions for Time Adjustment

G-Shock watches typically feature four buttons, each with a specific role during the time-setting process. Understanding their functions is essential for efficient time adjustment:

Adjust Button ADJ Enter or exit time-setting mode
Mode Button MODE Cycle through time settings (seconds, minutes, hours, etc.)
Forward Button FORW / + Increase the flashing value
Reverse Button REV / – Decrease the flashing value (available on some models)

Note that button labels and functions might slightly differ depending on the G-Shock model, but the general process remains consistent.

Adjusting Time Using Radio Signal or GPS Synchronization

Certain advanced G-Shock models support automatic time adjustment by synchronizing with radio signals or GPS satellites. This feature allows the watch to maintain highly accurate time without manual input.

To enable automatic synchronization:

  • Ensure the watch is in an area with good signal reception, ideally near a window for radio signals or outdoors for GPS.
