AvatarByArmando Lewellen Usage Guides

If you own a G-Shock watch, you already know it’s a reliable companion built to withstand tough conditions while keeping you on time. However, like any timepiece, there are moments when you need to adjust the time—whether it’s due to daylight saving changes, traveling across time zones, or simply resetting after a battery change. Knowing how to change the time on your G-Shock watch ensures you maintain its accuracy and functionality without hassle.

Changing the time on a G-Shock isn’t as complicated as it might seem. While these watches come with a variety of features and models, the process generally follows a straightforward method designed for ease and precision. Understanding the basic steps will help you confidently navigate the settings and customize your watch to reflect the correct time quickly.

In the following sections, you’ll discover the essential tips and key steps to adjust your G-Shock watch time efficiently. Whether you’re new to G-Shock or just need a refresher, this guide will prepare you to handle your watch’s time settings like a pro.

Adjusting Time on Digital and Analog-Digital G-Shock Models

Changing the time on G-Shock watches varies slightly depending on the model, especially between fully digital and analog-digital hybrid types. For digital models, the process involves entering the time-setting mode and using the buttons to adjust hours, minutes, seconds, and other settings. Analog-digital models require synchronization between the digital display and the analog hands.

To adjust the time on a typical digital G-Shock:

  • Hold down the Adjust button (usually at the top left) until the seconds digits start flashing, indicating you are in time-setting mode.
  • Use the Mode button (bottom left) to cycle through adjustable settings: seconds, hours, minutes, year, month, and day.
  • Press the Forward or Reverse buttons (usually at the bottom right and top right) to increase or decrease the values.
  • After setting each parameter, press Mode to move to the next.
  • Once all adjustments are complete, press Adjust again to exit the setting mode.

For analog-digital G-Shock watches, in addition to setting the digital time, you must also adjust the analog hands to match:

  • Enter the time-setting mode using the Adjust button as above.
  • Navigate to the hand adjustment mode, which is often indicated by the hands moving to a reference position.
  • Use the Forward and Reverse buttons to move the hands clockwise or counterclockwise to align with the digital time.
  • Confirm the setting by pressing the Adjust button.

Using Atomic Timekeeping and World Time Features

Many G-Shock watches come equipped with atomic timekeeping technology, allowing the watch to automatically sync with radio signals for precise time updates. If your model supports this, manual time adjustments may be limited or unnecessary, as the watch periodically calibrates itself.

To ensure atomic timekeeping is active:

  • Confirm the watch is set to the correct home city/time zone.
  • Place the watch near a window during the night for optimal signal reception.
  • The watch will attempt automatic synchronization at set times, often midnight or early morning.

For users who travel frequently, the World Time feature enables viewing and setting time zones from various cities globally. Here’s how to manage it:

  • Enter World Time mode by pressing the Mode button repeatedly until the city code appears.
  • Use the Forward and Reverse buttons to scroll through available city codes/time zones.
  • To set a new home city, usually, you press and hold the Adjust button while in World Time mode, then select the desired city.

Common Button Functions Across G-Shock Models

While button configurations can vary slightly, the following table summarizes typical button functions relevant to changing time on most G-Shock watches:

Button Typical Location Function in Time Setting
Adjust Top Left Enter/Exit time-setting mode, confirm changes
Mode Bottom Left Cycle through modes/settings (seconds, hours, minutes, etc.)
Forward (Start/Stop) Bottom Right Increase the value of the selected setting
Reverse (Split/Reset) Top Right Decrease the value of the selected setting

It is advisable to refer to your specific G-Shock model’s manual for precise button functions, as some limited edition or specialized models may differ.

Tips for Accurate Time Adjustment

To ensure your G-Shock displays the correct time after adjustment, consider the following best practices:

  • Set the watch in a well-lit environment to clearly see the display and button labels.
  • When adjusting analog hands, align them exactly with the digital time to prevent discrepancies.
  • If your watch features daylight saving time (DST) settings, toggle this on or off as appropriate for your region.
  • Regularly check for firmware updates or consult Casio’s website for model-specific instructions.
  • For solar-powered models, ensure adequate exposure to light so the watch maintains sufficient charge for accurate operation.

By following these guidelines, you can maintain the precision and reliability for which G-Shock watches are renowned.

Changing the Time on Your G-Shock Watch

Adjusting the time on a G-Shock watch involves accessing the watch’s settings through its buttons. G-Shock watches typically feature four buttons: Adjust, Mode, Forward, and Reverse (sometimes labeled differently). The exact button names and sequences can vary slightly depending on the model, but the process is generally consistent across most models.

Follow these steps to change the time on your G-Shock watch:

  • Enter Time Setting Mode: Press and hold the Adjust button (usually located at the top left) for about 3 seconds until the display starts flashing. This indicates you have entered the time-setting mode.
  • Select the Parameter to Adjust: Press the Mode button (typically bottom left) to cycle through the different time parameters such as seconds, hours, minutes, year, month, and day.
  • Modify the Value: Use the Forward button (usually bottom right) to increase the value. If your model includes a Reverse button (top right), use it to decrease the value.
  • Save and Exit: Once all the adjustments are made, press the Adjust button again to exit the setting mode and save the changes.

If your G-Shock watch includes additional features such as daylight saving time (DST) or 12/24-hour format, these can also be adjusted while in the time-setting mode by cycling through the parameters with the Mode button.

Detailed Button Functions for Time Adjustment

Button Common Location Primary Function During Time Setting
Adjust Top Left Enter/exit time setting mode; save changes
Mode Bottom Left Cycle through time parameters (seconds, hours, minutes, etc.)
Forward Bottom Right Increment the selected value
Reverse (if available) Top Right Decrement the selected value

Adjusting Additional Time Settings on Your G-Shock

Beyond simply setting the current time, G-Shock watches allow adjustment of several additional time-related features:

  • 12/24-Hour Format: Toggle between 12-hour and 24-hour time displays by selecting the hour parameter and pressing the Forward or Reverse button until the desired format appears.
  • Daylight Saving Time (DST): Enable or disable DST by cycling to the DST option in the time-setting mode and toggling it.
  • World Time Settings: Many G-Shock models feature world time functionality allowing you to set and view the time in different time zones. This is usually accessed via the Mode button outside the time-setting mode.

Tips for Accurate Time Setting on G-Shock Watches

To ensure your G-Shock watch displays accurate time, consider the following best practices:

  • Synchronize with a Reliable Source: Use an accurate clock, smartphone, or atomic time source to set your watch.
  • Reset Seconds First: When adjusting the seconds, reset to zero before moving on to hours and minutes for precise synchronization.
  • Check AM/PM Indicator: For 12-hour formats, verify the AM/PM setting to avoid time errors.
  • Use Auto Time Sync Models: Some G-Shock models offer Multi-Band 6 or GPS time synchronization, which automatically updates the time based on radio signals or satellite data, eliminating manual adjustments.
  • Consult the User Manual: For model-specific instructions, refer to the official Casio G-Shock manual as button functions may vary.
