Notes for Water Resistance Ratings
- I: The watch is not water-resistant. Avoid any contact with moisture.
- II: Do not pull out the crown if the watch is wet.
- III: Do not press the watch buttons underwater.
- IV: If the watch is exposed to salt water, rinse it thoroughly and dry it.
- V: The watch can be used for scuba diving (except for depths requiring a helium-oxygen mixture).
Some water-resistant watches feature leather straps. Do not wear these watches while swimming or engaging in any other activity where the strap may be submerged in water.
Watch Care
- Never attempt to open the case or remove the back cover yourself.
- 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.
- Do not expose the watch to extreme temperatures.
- While the watch is designed for normal use, avoid rough handling and dropping it.
- Do not fasten the strap too tightly. A finger should be able to fit 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 agents such as gasoline, solvents, aerosol cleaners, etc.
- When not using the watch, store it in a dry place.
- Avoid exposure to gasoline, cleaning solvents, aerosol sprays, adhesives, paint, etc. Chemical reactions caused by these materials can damage gaskets, the case, and the watch's finish.
- Some models feature silk-screened designs on the strap. Be careful when cleaning such straps to avoid damaging the designs.
For Watches with Plastic Straps...
- You may notice a whitish 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 a plastic strap, or storage in high humidity, can cause damage, tearing, or cracking. To ensure a long service life for the plastic strap, wipe it clean of dirt and moisture with a soft cloth whenever possible.
For Watches with Fluorescent Cases and Straps...
- Prolonged exposure to direct sunlight may cause the fluorescent color to gradually fade.
- Extended contact with moisture may cause the fluorescent color to gradually fade. If any moisture gets on the watch surface, wipe it off as soon as possible.
- Prolonged contact with any other wet surface may cause the fluorescent color to fade. Ensure the fluorescent surface is dry and avoid contact with other surfaces.
- Rubbing a surface with applied fluorescent paint against another surface may transfer the fluorescent paint to that surface.
