Types of Casio Watches
Casio makes many types of watches. The most common are:
- Digital watches (including standard and G-Shock models)
- Analog-digital watches
- Bluetooth models that connect to your phone
Each type has a slightly different way to reset.
Basic Reset for Digital Casio Watches
This method works for many digital Casio watches, like G-Shock and others.
- Enter Timekeeping Mode: Make sure your watch is showing the main time screen. Usually, press the Mode button until you see the time.
- Hold the Adjust button: Press and hold the Adjust button (often top left) for about 2 seconds. The screen will start flashing. This means you are in setting mode.
- Navigate with Mode: Press the Mode button to move through different settings like seconds, hours, minutes, year, month, and day.
- Reset values: Use the other buttons (usually Start/Stop or Light) to change values or reset them to zero.
- Exit setting mode: Press the Adjust button again to save and exit.
This process resets the time and date settings. It may fix many small issues.
How to Do a Factory Reset on Casio G-Shock Watches
Some G-Shock watches can be fully reset to factory settings. Follow these steps:
- Enter Timekeeping Mode: Press the Mode button until the time screen appears.
- Hold Adjust: Press and hold the Adjust button until the screen flashes.
- Find Reset option: Press Mode until you see “Reset” or “Reset All”.
- Start reset: Press the button usually on the top right (often called Start/Stop) and hold it. The watch will say “Clear All” or similar.
- Confirm reset: Wait until the blinking stops. The watch resets to factory settings.
- Exit: Press Adjust to leave the setting screen.
This clears all settings and returns the watch to its original state.
Resetting Analog Hands on Analog-Digital Casio Watches
Sometimes, the analog hands do not match the digital time. You can reset the hands like this:
- Enter Hand Setting Mode: Hold the Adjust button until the digital time flashes.
- Press Mode: Press Mode button until the hands start moving automatically.
- Adjust hands: Use buttons (usually Start/Stop or Light) to move the hands until they show the correct time.
- Save: Press Adjust to save the hand position.
This will sync the analog hands with the digital display.
After Battery Replacement – How to Perform AC Reset
If you change the battery, your watch may need an AC reset. Here’s how:
- Open the watch back carefully.
- Find the small metal contact marked “AC” inside the watch.
- Using a metal tool or tweezers, touch the “AC” contact and the battery’s negative side at the same time for about 2 seconds.
- The watch will reset and start working again.
This reset helps the watch recognize the new battery.
