Casio G-Shock Watches

To set up a Casio G-Shock watch, it's important to identify the proper model. Casio features at least 20 G-Shock watches since the first was created in 1983. Designed and built as the epitome of a tough watch, these timepieces offer a range of features to withstand extreme activities. All Casio G-Shock watches can withstand a free-fall drop up to 10 meters, have a 10-year battery life and are water resistant up to 10 bar as stated by the Casio website. Casio G-Shock watches are available in digital and analog styles and the manufacturer recommends checking the specific model manuals for complete time and calendar setup instructions. Accurate time and date settings ensure these watches perform at their highest level.

1. Set the Seconds

To set the time on the Casio G-Shock watch, start by setting the seconds. Hold the top left button to access the time-setting mode. Next, press the bottom left button three times until the field displaying the seconds flashes. Use the bottom left and right buttons to either increase or decrease the second numbers until accurate.

2. Set the Hour

To set the hour on a Casio G-Shock watch, press the bottom left button four times in a row until the hour field is flashing. Once again, use the bottom left and right buttons to cycle through the numbers until reaching the desired hour. Make sure to pay attention if the watch is set in 12- or 24-hour modes for accuracy and ease of use.

3. Set the Minute

To set up the proper minute configuration, press the bottom left button again until the minute field is flashing. This time, use the top right and left buttons until the desired minute configuration is reached.

4. Set the Month, Year and Day

Use the bottom left button again to set up the year on the Casio G-Shock watch. The left button only needs to be pressed once to enter the calendar mode. Use the top right and center left button to set the current year. For the 5413 model, use the rotary switch to change to calendar setting according to the Casio 5413 manual. Then use the bottom left, or C button, to cycle through hour, minute, year, month and day. For other models, continue pressing the bottom left button to enter different fields for month, year and day. Use the top right and left buttons to change the numbers.

Daylight Savings Time

Casio offers 19 watch models that can be set up for daylight savings time. By entering timekeeping mode on these models, it's possible to toggle the DST setting to on or off. Online manuals are available for download for each model for complete instructions on how to set up the daylight savings time feature according to Casio.


Exit the time- and calendar-setting modes by pressing the top right button twice firmly. Make sure none of the fields are flashing as this indicates the watch is still in time-setting mode.
