Important Information
Battery
The battery installed at the factory may discharge during shipping and storage. If the display becomes dim, replace the battery at the nearest authorized CASIO service center or dealer.
Water Resistance
Do not expose the watch to extreme temperatures. Although the watch is designed for normal use, avoid rough handling and dropping. Do not fasten the strap too tightly. A finger should fit between your wrist and the strap. Clean the watch and strap with a dry soft cloth, or a soft cloth dampened with a mild neutral detergent solution. Never use volatile agents (e.g., benzine, solvents, spray cleaners, etc.). When not in use, store the watch in a dry place. Avoid contact with benzine, cleaning solvents, spray aerosols, adhesives, paint, etc. Chemical reactions from these materials can damage gaskets, the case, and the watch's finish. Some models feature silk-screened designs on the strap. Clean such straps carefully to avoid damaging the designs.
For all watch categories, do not: press buttons underwater; set hands underwater; unscrew the crown underwater. If the watch is exposed to saltwater, rinse it thoroughly and dry it. Do not wear a watch with a leather strap while swimming. Avoid prolonged contact of leather straps with water.
For watches with plastic straps: You may find a white powdery substance on the strap. This substance is harmless to your skin or clothing and can be easily removed by wiping with a cloth. Sweat or moisture on plastic straps, or storage in high humidity, can cause damage, breakage, or cracking. To ensure a long service life for plastic straps, wipe them clean of dirt and water with a soft cloth whenever possible.
For watches with fluorescent cases and straps: Prolonged exposure to direct sunlight can cause fluorescent colors to fade gradually. Prolonged contact with moisture can cause fluorescent colors to fade gradually. If any moisture gets on the watch surface, wipe it off as soon as possible. Prolonged contact with any other wet surface can cause fluorescent colors to discolor. Ensure the fluorescent surface is dry and avoid contact with other surfaces. Strong friction of a surface with applied fluorescent paint against another surface can transfer the fluorescent paint to that surface.
CASIO COMPUTER CO., LTD. is not responsible for any damage that may occur from the use of this watch, nor does it accept claims from third parties.

Care for Your Watch
Never attempt to open the case or remove the back cover. The rubber gasket that protects the watch from water and dust should be replaced every 2-3 years. If moisture enters the watch, have it checked immediately by your nearest CASIO dealer or distributor.
Setting Current Time
1. Pull the crown to the second click. The second hand will move to the 12 o'clock position and stop.
2. Turn the crown to set the hands to the desired time. The hands will move only clockwise (forward).
3. After setting, return the crown to its normal position.
Diagram shows: Crown (Normal position, 1st click for date setting, 2nd click for time setting), Hour Hand, Minute Hand, Second Hand, Date display, 24-hour Hand.
Setting Current Date
- Pull the crown to the first click.
- Turn the crown towards you to set the desired date.
- After setting, return the crown to its normal position.
Try not to set the date between 9:00 PM and 1:00 AM.
Using the Stopwatch
This watch allows you to measure elapsed time up to 59 minutes and 59 seconds. The 1/20 second hand shows measured values only for the first 30 seconds of measurement.
- Press button 'A' to start measurement.
- Press button 'A' to stop measurement. You can resume measurement by pressing button 'A' again.
- Press button 'B' to reset the measured values. To have the 1/20 second hand show the current time's seconds again, press button 'B'.
Do not use the stopwatch if the crown is pulled out. If the home position of the stopwatch second hand and the 1/20 second hand do not match (hands should be at the 12 o'clock position), perform correction.
Synchronizing Stopwatch Hands
- Press button 'B' to reset the stopwatch.
- Pull the crown to the second click.
- Press button 'A' to move the stopwatch second hand.
- Press button 'B'.
- If the 1/20 second hand is at the 12 o'clock position, proceed to step 6. If not, press button 'B' to adjust its position.
- After synchronization, return the crown to its normal position.
Note that pulling the crown stops the second hand. Therefore, after synchronizing the hands, you may need to adjust the second hand's position.
Bezel Operation
Some watches are equipped with a rotating bezel. To measure elapsed time, align the bezel marker with the minute hand's position. After time has passed, the minute hand will point to a numerical value on the bezel, indicating the measured time.
