How Do You Set the Time on a Casio G-Shock Watch


Casio first introduced the G-Shock line of watches in 1983 and sold more than 100 million watches by 2017. This popular brand of durable watches for men and women are supposed to be nearly damage-proof. However, not everyone adapts to how to use this style of watch instantly. Read on to learn how to set the time on your Casio G-Shock if it needs to be reset.

Getting Familiar With the Watch Buttons

Unlike a typical watch that may have dials and winders, the Casio G-Shock line, for most model types, is essentially controlled through four buttons that appear on the edge of the face. The top left is the A button, and the top right is the B button. The lower left is the C button, and the lower right is the D button. Some model’s button arrangements are slightly different, with the bottom left and right buttons labeled D and E, with C being a long button located midway down the side. Other models have a button along the bottom, which is known as the L button. However, most G-Shock watches have the A through D configuration.

How to Set a G-Shock Watch Manually

If you need to change or update the time, you may want to set the time on your watch manually. To do so, you must enter into timekeeping mode. To put the watch into timekeeping mode, hold down your A button for a few seconds. Keep in mind that the A button is the same on all models. Once you do this, ADJ should appear on the screen, followed by SET. More modern versions of the watch may ask you to set the time zone prior to setting the time. Use the buttons ― top and bottom ― on the right side of the watch to navigate through the proper screens. Your watch may ask you if you are currently observing Daylight Savings Time. You can also choose 12-hour military format to display time or 24-hour standard time. 

How to Set for Atomic Timekeeping

More modern versions of the G-Shock watch may be compatible with atomic timekeeping. This means that the watch can reset itself with an atomic clock found somewhere in the world. To set for atomic timekeeping, take it off and place it in a window sill. The area should be free of obstruction and free of electronic signals that may interfere with updating the watch. Casio says it should set itself within 12 minutes or less, but letting it sit longer to be sure is recommended. 

How to Set Your Watch Via Your Phone

If you have a modern G-Shock that has Bluetooth capabilities, you can reset the time through your phone or tablet via Bluetooth. You will first need to download the Connected app from Casio, which is for G-Shock watches. Make sure Bluetooth is enabled on your phone and that the watch is within three feet of the phone. Run the app and hold the lower-left ― C in most cases ― button down on your phone for 4 seconds until a connection is made. 

If You Need Help Setting or Using Your Watch

If you still are having a hard time setting the time on your G-Shock watch and can’t locate your physical owner’s manual, it’s possible to look up your exact model number’s owner’s manual online. Every Casio G-Shock, whether it’s old or new, has a four-digit model number on the back that corresponds with a manual. Either enter the model number into the official Casio site for support or enter it along with “Casio G-Force” into a search engine for broader results. 

Features of G-Shock Watches

G-Shock series watches are popular with customers because of their durability, which includes water-resistance and shock-resistance. For example, the G-Shock GST-B100D-1ACR model offers up to 200 feet of water-resistance, which is perfect for those who love to swim or dive. It is also completely shock-proof. Other features of this and many G-Shock models include daily alarms and signals that you can set (also by entering timekeeping mode via button A), an eight-month battery length, and a full calendar mode. Different models are constructed of different materials, but many have a tough stainless-steel frame with mineral glass.
