3. Setup
3.1 Initial Charging
This watch is solar-powered. Before initial use, expose the watch dial to light for several hours to ensure it is sufficiently charged. Avoid covering the dial, as this is where the solar panel is located. A full charge provides approximately 5 months of operation until the hands stop.
3.2 Setting the Time and Date
- Pull out the crown to the first click for date adjustment, or to the second click for time adjustment.
- Rotate the crown to set the desired time or date.
- Push the crown back in to its normal position to start timekeeping.

4. Operating Instructions
4.1 Timekeeping
The watch displays hour, minute, and second hands for regular timekeeping. The 24-hour dial indicates the current time in a 24-hour format.
4.2 Using the Stopwatch
The 1-second stopwatch can measure up to 29 minutes and 59 seconds. It supports elapsed time, split time, and 1st-2nd place times.
- Press the upper pusher (A) to start the stopwatch.
- Press pusher (A) again to stop the stopwatch.
- Press the lower pusher (B) to reset the stopwatch to zero.
- For split time, press pusher (B) while the stopwatch is running to display the split time. Press pusher (B) again to return to elapsed time.
4.3 Date Display
The date is displayed in a window on the dial. Adjust the date as described in the "Setting the Time and Date" section if needed.
4.4 Battery Level Indicator
The watch features a battery level indicator. If the second hand moves at two-second intervals, it indicates a low battery level and requires exposure to light for charging.
5. Maintenance
5.1 Water Resistance
This watch is water resistant up to 100 meters. This means it is suitable for swimming and snorkeling, but not for scuba diving. Do not operate the crown or pushers while the watch is wet or submerged.
5.2 Cleaning
Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For the stainless steel band, a soft brush and mild soap solution can be used, followed by thorough rinsing and drying.
5.3 Storage
When not in use for extended periods, store the watch in a well-lit area to ensure continuous charging and prevent battery depletion. Avoid extreme temperatures and strong magnetic fields.
6. Troubleshooting
- Watch not running or hands stopped: The watch may be insufficiently charged. Expose the dial to bright light for several hours.
- Time or date is incorrect: Adjust the time and date manually using the crown as described in Section 3.2.
- Stopwatch not functioning correctly: Ensure the watch is fully charged. If issues persist, perform a full reset (refer to Casio's official support for model-specific reset procedures if available, or contact customer service).
- Condensation inside the crystal: This may indicate a breach in water resistance. Avoid further exposure to water and seek professional service immediately.
