Getting Started
Unpacking
Carefully remove your watch from its packaging. Inspect the watch for any visible damage. Ensure all protective films are removed from the crystal and case back.
Initial Charge
Your Casio MTPS120L watch is solar-powered. Before initial use, expose the watch face to bright light (natural sunlight is ideal) for several hours to ensure it is sufficiently charged. Avoid covering the watch face during charging. A fully charged watch can operate for an extended period in darkness.

Setting the Time and Date
To set the time and date on your watch, follow these steps:

- Pull out the crown: Gently pull the crown (the knob on the side of the watch) out to the first click for date adjustment, or to the second click for time adjustment.
- Setting the Date: If the crown is at the first click, rotate it to adjust the day and date. Note that the day display supports both English and Spanish. Rotate until the desired day and date are shown. Avoid setting the date between 9:00 PM and 1:00 AM, as this may interfere with the automatic date change mechanism.
- Setting the Time: If the crown is at the second click, rotate it to move the hour and minute hands. Advance the hands clockwise until the correct time is displayed. Ensure you differentiate between AM and PM for accurate date change.
- Push in the crown: Once the time and date are set, push the crown back in completely to its normal position. This will start the watch movement.
Solar Charging
The Casio MTPS120L watch utilizes a solar cell on its dial to convert light into electrical energy, which is stored in a rechargeable battery. Regular exposure to light is crucial for maintaining optimal performance.
Charging Guidelines
- Expose the watch face to light whenever possible.
- Avoid prolonged storage in dark places, as this can deplete the battery.
- Charging time varies depending on the light source intensity. Direct sunlight provides the fastest charge.
Low Battery Indicator
If the watch's second hand moves at two-second intervals, it indicates that the battery charge is low. Immediately expose the watch to bright light for charging. The watch will resume normal operation once sufficient charge is accumulated.
Water Resistance
Your watch is rated for 100-meter water resistance. This means it is suitable for everyday use, swimming, and snorkeling. However, it is not suitable for scuba diving.
Usage Guidelines
- Do not operate the crown or push buttons while the watch is wet or submerged in water.
- After exposure to saltwater, rinse the watch with fresh water and wipe it dry.
- Avoid exposing the watch to hot water or steam, as this can compromise the seals.
Maintenance
Proper care will help maintain the appearance and function of your watch.
Cleaning
- Wipe the watch case and crystal with a soft, dry cloth regularly.
- For the cloth strap, gently clean with a damp cloth and mild soap if necessary, then allow it to air dry completely. Avoid harsh chemicals.
Strap Care
The watch comes with a durable cloth strap. Inspect the strap periodically for signs of wear or damage. If the strap becomes severely worn or damaged, consider replacing it to prevent accidental loss of the watch.
Storage
When not wearing the watch, store it in a location where it can receive some light to maintain its charge. Avoid extreme temperatures, direct sunlight for prolonged periods (when not charging), and strong magnetic fields.
