Caring for Your Watch

• Never attempt to open the case or remove the back cover yourself.
• The gasket that protects the watch from water and dust should be replaced every 2 to 3 years.
• If moisture enters the watch, have it checked immediately by your nearest dealer or a CASIO distributor.
• Do not expose the watch to extreme temperatures.
• Although the watch is designed for active daily use, wear it carefully and avoid dropping it.
• Do not fasten the strap too tightly. You should be able to fit a finger between your wrist and the strap.
• To clean the watch and strap, use a dry soft cloth or a soft cloth dampened with a mild neutral detergent solution. Never use volatile substances (e.g., gasoline, solvents, spray cleaners, etc.).
• When not using your watch, store it in a dry place.
• Avoid contact with gasoline, cleaning solvents, spray aerosols, adhesives, paint, etc. Chemical reactions caused by these materials can damage gaskets, the case, and the watch's polish.
• Some watch models feature silk-screened designs on their straps. Be careful when cleaning such straps to avoid damaging the designs.

Strap Care

For watches with plastic straps:

You may notice a white powdery substance on the strap. This substance is harmless to your skin or clothing and can be easily removed by simply wiping with a cloth. Exposure of a plastic strap to sweat or moisture, as well as storage in high humidity conditions, can lead to damage, tearing, or cracking of the strap. To ensure a long service life for the plastic strap, wipe it 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 the fluorescent coloring to gradually fade.
• Prolonged contact with moisture can cause the fluorescent coloring to gradually fade. If any moisture gets on the watch surface, wipe it off as soon as possible.
• Prolonged contact with any other damp surface can cause the fluorescent coloring to discolor. Ensure that moisture is removed from the fluorescent surface 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.

Slight condensation may form on the inside of the glass when the product is used in conditions of rapid temperature changes. This phenomenon is due to the laws of physics and is not a defect.

CASIO COMPUTER CO., LTD. is not responsible for any damage that may arise from the use of this watch, and does not accept any claims from third parties.
