Finding the "Adjust" button – often on the watch case – is the first step to setting the time on a G-Shock watch. Press and hold this button to flash the time on the screen. To access options for configuring the time zone, use the "Mode" button. Please select your time zone using the "+" and "-" buttons. Continue by pressing "Adjust" after selecting your time zone. From there, you can use the "+" and "-" buttons to fine-tune the hour setting. Follow the same steps for the minute option. Additional parameters, such as daylight saving time, 12- or 24-hour format, and possibly other models, may be similarly adjustable. When you have finished adjusting all the parameters click the "Adjust" button to apply your modifications. Please refer to your G-Shock's handbook for specific instructions that are designed to work with your model, as the locations and steps of the buttons may vary significantly. If you don't have it, you can usually find the manual online through reputable sources like the official Casio website.
