Setup
Initial Time Setting
Upon first use or after a battery change, it is necessary to set both the analog and digital times. Refer to the full manual for specific button operations to synchronize the analog hands with the digital time.
Battery Information
The Casio AEQ-120W watch is powered by a CR2025 battery, designed for an approximate lifespan of 10 years. This minimizes the need for frequent battery changes. When replacement is eventually required, it is recommended to have it performed by a qualified watch technician to ensure water resistance integrity.
Operating Modes and Functions
Your watch features multiple modes accessible via the mode button (typically located on the left side of the watch case). Pressing this button cycles through the available modes.
World Time
The World Time mode allows you to view the current time in 30 cities across various time zones. To select a city, use the adjustment buttons (usually on the right side). The digital display will show the time for the selected city.
Daily Alarm
The watch includes 3 daily alarms, with one featuring a snooze function. To set an alarm, navigate to the Alarm mode and use the adjustment buttons to set the desired alarm time. Activate or deactivate alarms as needed.
Countdown Timer
The countdown timer can be set for a specific duration, alerting you when the time expires. In Countdown Timer mode, set the start time using the adjustment buttons and then initiate the countdown.
Stopwatch
The 1/100-second stopwatch function is used for measuring elapsed time. Enter Stopwatch mode, then use the start/stop and reset buttons to operate the timer.
Telememo
The Telememo feature allows you to store up to 30 sets of names and phone numbers. Each entry can accommodate an 8-character name and a 16-digit telephone number. The watch includes an auto-sort function and displays remaining memory capacity. To use, enter Telememo mode and follow the on-screen prompts for data entry and retrieval.
12-Hour / 24-Hour Format
The digital display supports both 12-hour and 24-hour time formats. This setting can typically be toggled within the Timekeeping mode's settings.

Maintenance
Water Resistance
The Casio AEQ-120W watch is water resistant up to 100 meters (10 ATM). This makes it suitable for swimming and recreational water activities. Avoid operating buttons while the watch is submerged to prevent water ingress.
Cleaning
To clean your watch, wipe it with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying. Avoid using harsh chemicals or solvents, as these can damage the resin materials.
Storage
When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures to preserve its materials and battery life.
Troubleshooting
Time Inaccuracy
If the watch's time is inaccurate, ensure that the digital time is correctly set and that the analog hands are synchronized with the digital display. Refer to the setup section for time adjustment procedures.
Display Issues
If the digital display is dim or blank, the battery may be low or depleted. While the watch has a 10-year battery life, environmental factors can affect this. If issues persist, consult a professional watch service.
Buttons Not Responding
Ensure the watch is not in a locked mode or that water is not interfering with button operation. If buttons remain unresponsive, professional inspection may be required.
