Use the following reference to confirm each menu option before you begin changing time, timezone, or display settings on your G-Shock.
| Operation | Mode Entry | Button Sequence | Confirmation |
|---|---|---|---|
| Time Setting | Time Adjustment | Mode + Left/Right, then Enter | Seconds flash, adjust hours/minutes |
| Timezone Offset | World Time | Mode + Left/Right, then Enter | UTC offset selection |
| DST Toggle | DST Settings | Mode + Left/Right, then Enter | Enable or disable daylight saving |
| Format & Sound | Preferences | Mode + Left/Right, then Enter | Beep tone and display format |
| Backlight Timer | Backlight | Mode + Left/Right, then Enter | Duration before auto-off |
Time Setting Mode Overview
Access the time setting mode to correct hours and minutes after battery replacement or travel. This core G-Shock setting keeps your schedule and timestamps accurate.
Entering time adjustment requires a specific sequence of buttons, otherwise the watch will ignore changes or exit setup prematurely. Follow each step precisely.
Once you confirm the entry, the seconds digits begin to flash, signaling that you can safely modify the current time without affecting the date calendar.
Adjusting Time and Seconds
Use the left and right buttons to cycle through hours and minutes, then press Enter to move between fields. Each press increments the active value, and large digits confirm your input.
After setting the correct time, press Mode to save and exit. The watch returns to normal timekeeping, and a short vibration may confirm successful storage of the new G-Shock setting.
Avoid making adjustments near strong magnetic fields, since interference can temporarily disrupt the quartz regulation and require recalibration.
World Time and Timezone Offset
World Time mode lets you store multiple cities and switch instantly when coordinating with global teams or planning calls across regions.
Each location is tied to a UTC offset, which you select by holding Mode while pressing left or right. This G-Shock setting determines the base time before applying local daylight saving rules.
When you travel, update the offset first, then set the local time, ensuring your itinerary stays aligned with official time standards.
Daylight Saving and Display Preferences
DST settings automatically shift the clock forward or backward by one hour according to regional rules, reducing manual updates during seasonal transitions.
Display preferences control beep volume, tone, and whether the backlight activates with each button press. Adjust these options in the preferences menu using the same navigation pattern as time setting.
For clarity in quiet environments, you can disable the confirmation beep while keeping the backlight functional for evening checks.
Recommended Setup Checklist
- Verify the current time against an official source before saving adjustments
- Set the correct UTC offset when using world time to avoid systematic errors
- Enable DST only if your region observes daylight saving changes
- Confirm beep and backlight preferences for comfortable daily use
- Test the alarm and world time displays after any time setting operation
FAQ
Reader questions
How do I change the time on my G-Shock without affecting the alarm?
Enter time setting mode, adjust hours and minutes, then press Mode to save. The alarm data remains untouched because it is stored separately from the real-time clock.
What does the offset setting do in world time mode?
The offset defines the number of hours added or subtracted from UTC, forming the foundation for each city display. Changing the offset updates the local time immediately without additional input.
Can I reverse accidental changes to the time during setup?
While seconds are flashing, you can use left and right to decrement values. If you exit time setting mode without pressing Mode to save, the watch discards changes and reverts to the previous time. The watch recalibrates the quartz oscillator and rewrites data to nonvolatile memory. This pause is normal and ensures the new G-Shock setting persists after battery removal.
