Remember, practice makes perfect, so don't be afraid to experiment and get comfortable with the button layout. Knowing what each button does will save you a lot of frustration in the long run. It is also good to keep in mind that some buttons may have multiple functions depending on the mode you are in. So, always pay attention to the display and what it's prompting you to do. With a little patience and practice, you'll be navigating your G-Shock like a pro in no time!

Setting the Time on Your Casio G-Shock GA-100

Okay, let's get down to the most crucial function: setting the time. There’s nothing more embarrassing than flashing the wrong time, right? Here’s how to get your Casio G-Shock GA-100 synchronized with the world. First, press and hold the Adjust button (top left) until the city code starts flashing. This indicates you're in the time setting mode. Next, use the Forward (bottom right) or Reverse (top right) buttons to select your city code. This is super important because it sets the base time zone for your watch. After you've selected your city code, press the Mode button (bottom left) to cycle through the different settings: DST (Daylight Saving Time), 12/24-hour format, seconds, hours, minutes, year, month, and day. Use the Forward or Reverse buttons to adjust each setting to your preference. Once you've set everything correctly, press the Adjust button again to save your changes and exit the setting mode. Voila! Your G-Shock GA-100 is now displaying the correct time. If you live in an area that observes Daylight Saving Time, make sure you have the DST setting turned on. This will ensure that your watch automatically adjusts for the time change. And remember, if you ever need to make changes, just repeat these steps to enter the time setting mode and adjust accordingly. With a little practice, you'll be able to set the time on your G-Shock GA-100 in a matter of seconds!
