A common issue owners face is when on their ga2100 the time indicated by the hands is different from the digital time. This happens if the watch experiences strong magnetism or shocks.

Then press the Mode button (bottom left) to adjust the main hands. Use the right-side buttons to align both the hour and minute hands exactly to the 12 o’clock position. Once they are aligned, press Adjust to exit, and the analog hands will automatically spin to match the digital time.

Troubleshooting: Analog Hands Don’t Match Digital Time

How To Turn On Or Off Daylight Saving Time On Casio G-Shock GA-2100
If you need to know how to turn on or off daylight saving time on casio g shock GA-2100 (popularly dubbed the “Casioak”), the process is handled directly through the digital module. Because standard Casio GA-2100 models (Module 5611) do not have Bluetooth auto-sync or Multi-Band 6 atomic radio reception, you must manually toggle the Daylight Saving Time (DST) setting twice a year when time shifts in spring and autumn.
Before adjusting, familiarize yourself with the 4-button layout on the octagonal case:
| Button | Position | Function in DST / Setting Mode |
|---|---|---|
| Button A (Adjust) | Top-Left | Hold for 2 seconds to enter/exit Timekeeping Setting Mode |
| Button B (Light) | Top-Right | Illuminates the dial; toggles backwards during manual number setting |
| Button C (Mode) | Bottom-Left | Cycles through settings (City Code → DST → 12/24H → Seconds → Hour → Minute) |
| Button D (Start) | Bottom-Right | Toggles DST state between ON and OFF |
Step-by-Step: How to Change Daylight Savings on G-Shock GA-2100
- Ensure Timekeeping Mode: Check that your watch is in standard Timekeeping Mode (the small LCD sub-dial displays the digital seconds/time or day/date).
- Enter Setting Mode: Press and hold Button A (Adjust) for approximately two seconds. Release the button when “SET” flashes on the display and the three-letter Home City code (such as NYC, LON, or TYO) blinks.
- Navigate to the DST Screen: Press Button C (Mode) once. The LCD display will switch from the Home City code to the g shock ga 2100 dst on off menu, displaying “DST” alongside the flashing status (“OFF” or “ON”).
- Toggle DST On or Off: Press Button D (Start) to switch the casio g shock dst setting. Selecting ON advances the digital clock by exactly +1 hour and turns on the small “DST” indicator dot on the LCD. Selecting OFF returns the watch to standard time.
- Save and Exit: Press Button A (Adjust) once to lock in your changes. The LCD will stop flashing and return to the live time display.
Analog Hands Auto-Adjustment vs. Hand Home Position (H.SET)
Once you exit setting mode, the motorized gear train on the GA-2100 automatically rotates the analog hour and minute hands forward or backward to match the newly adjusted digital time. You do not need to manually turn the crown or reset the hands during a normal DST switch.
Note: If your analog hands show a different hour or minute than the LCD after updating DST, the physical hand alignment may have slipped due to magnetic exposure or physical impact. If this occurs, perform a Hand Home Position Adjustment (H.SET) by holding Button A for 5 seconds until “H.SET” flashes, then re-zero the hands to the 12 o’clock position.
Frequently Asked Questions: Casio G-Shock DST Settings
How to turn on or off daylight saving time on casio g shock if the DST indicator does not appear?
To access the DST menu on a Casio G-Shock GA-2100, ensure you are in standard Timekeeping Mode. Hold Button A (Adjust) for two seconds until SET flashes and the Home City code blinks. Then press Button C (Mode) once to reach the DST screen. Press Button D (Start) to toggle between ON and OFF, then press Button A to confirm and save.
Why didn’t my G-Shock GA-2100 analog hands change when I turned on DST?
On the GA-2100 (Module 5611), the analog hands automatically rotate one hour forward or backward upon exiting setting mode with Button A. If the hands do not align with the digital readout, perform a Hand Home Position Adjustment (H.SET) by holding Button A for 5 seconds to calibrate the physical hands to 12:00.
Does the standard Casio G-Shock GA-2100 update daylight saving time automatically?
No. The standard Casio G-Shock GA-2100 requires manual DST toggling. Only Bluetooth-enabled variants like the GA-B2100 can automatically sync Daylight Saving Time via the Casio Watches smartphone app.
