Frequently Asked Questions - Collection LA680WEA-7EF CASIO
How do I set the time on my Casio LA680WEA-7EF?
Press and hold the Adjust button (usually top-left) for about 3 seconds until the seconds digits flash. Use the Mode button (bottom-left) to cycle through settings (seconds, hour, minute, etc.), and use the Start/Stop button (top-right) to change values. Press Adjust again to exit.
How do I change the battery?
Use a small screwdriver to open the back cover. Remove the old CR2016 battery and insert a new one with the positive side facing up. Ensure the gasket is seated properly to maintain water resistance. It is recommended to have the battery replaced by a professional.
Is this watch waterproof?
The watch is water resistant to 30 meters (3 bar). It can withstand splashes and brief immersion in water, but not swimming or diving. Avoid pressing buttons underwater.
How do I use the stopwatch?
Press the Mode button until the stopwatch display appears (indicated by 'ST'). Press Start/Stop to start and stop timing. Press Reset (bottom-right) to reset to zero. The stopwatch measures up to 24 hours in 1/100 second increments.
How do I set the alarm?
Press Mode until the alarm display (usually 'AL' or bell icon) appears. Press and hold Adjust until the hour digits flash. Use Start/Stop to set the hour and minutes, then press Adjust to confirm. Press the Reset button to turn the alarm on/off.
What does the 'SNZ' indicator mean?
SNZ stands for snooze. When the alarm sounds, pressing any button will snooze it for about 5 minutes. The alarm will sound again automatically. To disable snooze, turn the alarm off.
How do I adjust the display contrast?
This model has a fixed LCD display and does not have contrast adjustment. The display is designed to be readable under normal lighting conditions, and the backlight helps in low light.
Can I wear this watch while showering?
It is not recommended. Although the watch is water resistant to 30m, hot water and steam can damage the seals. Avoid showering, bathing, or sauna use.
How do I activate the backlight?
Press the Light button (usually top-right or dedicated button) to illuminate the display for a few seconds. The backlight uses an LED and is battery-efficient.
My watch is not keeping accurate time. What should I do?
First, check if the battery is low (display may dim). If the battery is fine, reset the watch by pressing the Reset button (bottom-right) with a pointed object. Then reset the time. If the problem persists, the watch may need servicing.
