The basic steps to set the time on your G-Shock

Most G-Shock watches use the same method: press the button labeled Mode until you reach the timekeeping screen, then press Adjust to enter edit mode. Once you are in edit mode, use the forward and back buttons to change the hours and minutes, then press Mode again to save and exit. The exact button names and sequence vary slightly by model, so check your specific watch's manual first — the model number is printed on the case back.

The process takes less than a minute once you know which buttons to use. If your watch has already been set and you only need to correct the time by a few minutes, you do not need to enter edit mode at all — some models let you hold down a button to fast-forward through the minutes without entering the full adjustment menu.

Key Takeaways

  • Most G-Shock models require you to press Mode until the time display appears, then press Adjust to enter edit mode.
  • Once in edit mode, the forward and back buttons (usually labeled with arrows) let you change hours and minutes one digit at a time.
  • Pressing Mode again saves your changes and returns you to normal timekeeping mode.
  • Your specific model number (found on the case back) determines the exact button sequence, so consult your manual if the standard method does not work.
  • Some G-Shock models let you hold a button to fast-forward through minutes without entering full edit mode.

Finding your model number and manual

The model number is stamped or printed on the back of the watch case, usually near the bottom. It typically starts with letters like DW, GA, GD, or GW followed by numbers. Write down the full model number before you search for instructions.

Once you have the model number, search for "[model number] manual" on Google or visit the Casio support website directly. Casio hosts PDF manuals for nearly every G-Shock ever made, and the timekeeping section usually appears within the first few pages. If you cannot find the manual online, the instruction booklet that came with your watch contains the same information.

The standard button sequence for most G-Shock models

On digital G-Shock watches without a dial, the standard layout is: Mode button on the upper left, Adjust button on the upper right, and forward/back buttons on the lower left and right. Press Mode repeatedly until the time display shows on the main screen. The display will cycle through different functions — timekeeping, alarm, stopwatch, and timer — so count the presses or watch for the clock icon.

Once the time is showing, press Adjust. The hours digit will begin to blink, telling you that edit mode is active. Press the forward button (lower right) to increase the hours, or the back button (lower left) to decrease them. After you set the hours correctly, press Adjust again to move to the minutes digit, then use the same forward and back buttons to adjust the minutes. Press Mode when you are finished to save and return to normal mode.

If you overshoot a number, keep pressing forward — the digits wrap around, so pressing forward from 23 hours returns you to 00. This is faster than pressing back many times.

Analog G-Shock watches with a dial

G-Shock models with an analog dial and digital display use a different method. Press Mode until you see the time adjustment screen on the digital portion, then press Adjust. The hour hand will move to show which digit is being edited. Use the forward and back buttons to change the hours, then press Adjust to move to the minutes. The minute hand will move as you adjust. Press Mode to save when finished.

On analog models, the hands may not land exactly on the minute markers during adjustment — this is normal. Once you press Mode to save, the hands will snap into the correct position. If the hands seem misaligned after you save, the watch may need a full reset, which requires holding down a button for several seconds. Check your manual for the reset procedure specific to your model.

What to do if the standard method does not work

If pressing Mode does not cycle through the functions, or if Adjust does not enter edit mode, your watch may be in a different mode or the buttons may be labeled differently. Some G-Shock models use a single button to cycle through both mode selection and time adjustment. Others require you to hold a button for two seconds rather than press it once.

The fastest solution is to search your model number plus "how to set time" on YouTube. Many G-Shock owners post short videos showing the exact button sequence for their model, and watching someone do it is often clearer than reading instructions. If you still cannot find the answer, Casio's customer service can walk you through it by phone or email — contact information is on their website.

Resetting the time if you get stuck in edit mode

If you press buttons and the time starts changing unexpectedly, or if you cannot exit edit mode, do not panic. Press Mode repeatedly until the display returns to normal timekeeping. If that does not work, remove the battery for 30 seconds and reinstall it — this resets most G-Shock watches to their default state. You will need to set the time again, but the watch will be responsive to button presses.

Some G-Shock models have a dedicated reset button on the case back, usually labeled with an R. Pressing it with a small tool resets the watch completely. Check your manual to see if your model has one before you try this, because a full reset will also clear any alarms or custom settings you have programmed.

Frequently Asked Questions

Why does my G-Shock keep resetting the time to the wrong hour?

This usually means you did not fully exit edit mode. Press Mode one more time after you finish adjusting the minutes — you should see the time display return to normal without any blinking digits. If the time keeps changing on its own, the watch may have a stuck button or a low battery. Try replacing the battery first, as low power can cause erratic behavior.

Can I change just the minutes without changing the hours?

Yes. Enter edit mode by pressing Mode and then Adjust. When the hours digit blinks, press Adjust again when ready without changing anything. The cursor will move to the minutes digit, and you can adjust only that. Press Mode to save.

What if I do not have the manual for my G-Shock?

Search your model number (found on the case back) plus "manual PDF" on Google, or visit Casio's support page and use their manual search tool. If the model is discontinued, try searching the model number plus "how to set time" on YouTube — user videos often cover older models that are no longer in print.

Does changing the time affect the alarm or stopwatch?

No. Adjusting the time only changes the hours and minutes display. Alarms, stopwatch records, and timer settings remain unchanged. The alarm will still go off at the time you set it for, using the new corrected time as the reference.

Why is the time still wrong after I set it?

Make sure you pressed Mode to save after adjusting the minutes. If the digits were still blinking when you stopped, the changes were not saved. Also check that you set the correct 12-hour or 24-hour format — some G-Shock models display time in both formats, and you may have set it in the wrong one. Your manual will show how to toggle between 12-hour and 24-hour display.
