The Casio Edifice is a line of wristwatches for men. The Edifice comes in several models with different features, but the basic functions remain the same across the line of watches. All Edifice watches are made with a stainless steel body that is water resistant up to 100 meters.

The digital timepiece on an Edifice watch is set using the function buttons on the outer part of the watch face. To set the digital time, press and hold the upper left button until the seconds starts blinking. Press the lower right button to reset the seconds to "00."

Push the lower left button to move to the Daylight Savings Time portion of the watch. Use the lower right button to toggle between "On" and "OFF."

Press the lower left button twice. The hours unit will start blinking. To advance the hour, press the lower right button repeatedly until the correct hour is displayed. If you need to move the hours unit backwards, press the middle right button until the correct hour is displayed. When the hour is set, press the lower left button to switch to minutes, and use the same commands to change the minutes unit.

After the time is set, press the upper left button to exit the digital time setting function.

You may find after setting the digital timepiece that the analog display does not match. When this occurs, you need to set the analog time. To set the analog time, press the lower left button 6 times. Next, press and hold the upper left button until the digital time starts to blink. This indicates that you are in analog time setting mode.

Analog time adjustment is completed using the lower right button. Every time you press the button, the analog time will advance 20 seconds. If you need to make a big change to the analog time, press and hold the lower right button to make the hands move faster. Once the analog time is set, press the upper left button to exit the analog time setting mode.

If you are in a dark location and are unable to see the face of your Edifice watch, press the "Illumination" button on the top right corner of the watch. The entire watch face will light up for easy viewing.

The Casio Edifice also has an auto illumination feature. When activated, the watch face will light up, depending on the angle the watch is facing. To turn on auto illumination, press and hold the lower right button until the auto light icon displays on your watch. When the auto light is on, your watch will light up when you hold your arm parallel to the ground and twist the watch toward you more than 40 degrees.

If you decide to turn off this feature, press and hold the lower right button until the auto light icon disappears.
