3.2 Setting the Time
- Pull the crown (the knob on the side of the watch) out to the first click position.
- Rotate the crown to move the hour and minute hands to the desired time. Ensure AM/PM is correctly set if your watch has a 24-hour indicator or if you are setting the date.
- Push the crown back in completely to start the watch and seal it.
3.3 Setting the Date
The date mechanism should only be adjusted when the watch hands are positioned between 6:00 AM and 9:00 PM to prevent damage to the internal gears. Adjusting the date outside this window may cause the date to not change correctly or damage the mechanism.
- Pull the crown out to the first click position.
- Rotate the crown counter-clockwise (or clockwise, depending on the specific movement) to advance the date to the desired setting.
- Once the date is set, push the crown back in completely.
3.4 Band Adjustment
The Casio FT500WC-1BV features an adjustable cloth/Velcro band. To adjust, simply detach the Velcro strap, wrap it around your wrist, and re-secure the Velcro for a comfortable and snug fit. Ensure the watch is not too tight to allow for proper circulation.
4. Operation
4.1 Using the Illuminator LED Light
To illuminate the watch face in dark environments, press the dedicated light button, typically located on the side of the watch case. The LED light will activate for a few seconds, providing visibility to read the time.
- Note: Frequent use of the illuminator will reduce battery life.
4.2 Water Resistance Guidelines
Your watch is water resistant to 100 meters (10 BAR). This means it is suitable for everyday use, swimming, and snorkeling. It is not suitable for scuba diving or high-impact water sports.
- Do not operate the crown or any buttons while the watch is wet or submerged.
- After exposure to saltwater, rinse the watch with fresh water and wipe it dry.
- Avoid exposing the watch to hot water, steam, or extreme temperature changes, as this can compromise the water resistance seals.
5. Maintenance
5.1 Cleaning Your Watch
- Wipe the watch case and crystal with a soft, dry cloth.
- For the cloth band, if it becomes dirty, it can be gently hand-washed with mild soap and water. Ensure it is thoroughly dry before reattaching to the watch or wearing.
- Avoid using chemical cleaners or solvents, as these can damage the watch's finish or materials.
5.2 Battery Replacement
The watch is powered by one nonstandard battery. When the watch stops running or the illuminator light becomes dim, it is an indication that the battery needs replacement. Battery life is approximately 5 years under normal use.
- Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
- Do not attempt to replace the battery yourself, as this may void the warranty or damage the watch.
5.3 Storage
When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing it near strong magnetic fields, which can affect timekeeping accuracy.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch is not running. | Battery is depleted. Crown is pulled out. | Push the crown in completely. If still not running, replace the battery by a professional. |
