Setup
Initial Charging
Your Casio MTP-S100E-7BVCF watch is equipped with a solar charging system. To ensure proper operation, expose the watch face to light for several hours before initial use. Direct sunlight is most effective, but fluorescent light can also charge the watch. Avoid covering the watch face when charging.

Setting the Date
- Pull the crown out to the first click.
- Rotate the crown to adjust the date display.

Note: Avoid setting the date between 9:00 PM and 1:00 AM, as this may interfere with the automatic date change mechanism.
Operating Your Watch
Timekeeping
The watch displays hours, minutes, and seconds. The solar power system continuously recharges the internal battery, ensuring consistent operation under normal light exposure.
Date Display
The date is displayed in a window at the 3 o'clock position. The date automatically advances once every 24 hours.
Water Resistance
This watch is water resistant to 50 meters (165 feet). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Do not operate the crown while the watch is wet or submerged.
