Setting the Time on Different Casio Watch Models

Casio watches come in a variety of models, each with unique features and methods for adjusting the time. It is essential to identify your watch model to apply the correct procedure. The most common categories include digital, analog-digital, and atomic or radio-controlled watches.

For digital models, the process usually involves entering the time-setting mode by pressing and holding a specific button, often labeled “Adjust” or “Mode.” Once in the setting mode, you can cycle through the time units (hours, minutes, seconds) using the “Mode” button and change their values with the “Start/Stop” or “Light” buttons.

Analog-digital models require additional steps because they combine mechanical hands with a digital display. Adjusting the digital time first typically syncs the analog hands automatically, but manual hand adjustment might be necessary if they fall out of sync.

Atomic or radio-controlled watches automatically synchronize time with a radio signal. Manual time setting is usually unnecessary unless the watch is out of range or the signal is weak. In such cases, you can override automatic settings to adjust the time manually.
