Setup and Initial Charging
- Unpacking: Carefully remove the watch from its packaging. Inspect for any visible damage.
- Initial Charge: Your watch is solar-powered. Before first use, expose the watch face to bright light (natural sunlight is ideal) for several hours to ensure a full charge. Avoid placing it in direct sunlight for extended periods in extremely hot environments to prevent damage.
- Checking Charge Level: The second hand will move at two-second intervals if the battery is low. Once sufficiently charged, it will return to normal one-second interval movement.
Operating Instructions
Setting the Time
- Pull out the Crown: Gently pull the crown (the knob on the side of the watch) out to the second click position. The second hand will stop.
- Adjust Time: Rotate the crown to set the hour and minute hands. Ensure the AM/PM setting is correct, especially when setting the date. The 24-hour markers on the dial can assist with this.
- Push in the Crown: Once the time is set, push the crown back into its normal position. The second hand will resume movement.
Setting the Day and Date
- Pull out the Crown: Gently pull the crown out to the first click position.
- Adjust Date: Rotate the crown clockwise to change the date.
- Adjust Day: Rotate the crown counter-clockwise to change the day of the week.
- Push in the Crown: Once the day and date are set, push the crown back into its normal position.
Note: Avoid setting the date between 9:00 PM and 1:00 AM, as this may interfere with the automatic date change mechanism.
Care and Maintenance
- Water Resistance: The watch is 100M water resistant. This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water. It is suitable for swimming and snorkeling. Do not operate the crown or buttons while the watch is wet or submerged.
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For the resin band, you can use a mild soap solution and rinse thoroughly.
- Temperature: Avoid exposing the watch to extreme temperatures (hot or cold) for prolonged periods, as this can affect its accuracy and battery life.
- Chemicals: Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the case, band, or gaskets.

Troubleshooting
- Watch Not Running: Ensure the watch has been adequately charged by exposing it to bright light. If the second hand is moving at two-second intervals, it indicates a low charge.
- Incorrect Time/Date: Refer to the "Setting the Time" and "Setting the Day and Date" sections to re-adjust.
- Water Inside Watch: If moisture appears inside the watch, stop using it immediately and contact an authorized Casio service center.
