Watch Care
- Replace the gasket protecting the watch from water and dust every 2-3 years.
- If water enters the watch, have it checked immediately by an authorized CASIO dealer.
- Avoid exposing the watch to extreme high or low temperatures.
- While designed for normal use, avoid rough handling and dropping the watch.
- 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 water-mild neutral detergent solution. Never use volatile solvents like gasoline, thinners, spray cleaners, etc.
- When not in use, store your watch in a dry place.
- Avoid contact with gasoline, cleaning solvents, aerosol sprays, adhesives, paints, etc. Chemical reactions from these substances can damage gaskets, the case, and the watch's finish.
- Some models have silk-screened designs on the strap. Clean these straps carefully to avoid damaging the designs.
For watches with resin straps:
- You may notice a white powdery substance on the resin strap. This substance is harmless to skin or clothing and can be easily removed by wiping with a soft cloth.
- Exposure of the resin strap to sweat or moisture, or storage in high humidity, can cause damage or cracking. To ensure a long life for the resin strap, wipe it clean of dirt and moisture with a soft cloth as often as possible.
For watches with fluorescent cases and straps:
- Prolonged exposure to direct sunlight may cause the fluorescent color to fade gradually.
- Prolonged contact with moisture may cause the fluorescent color to fade. If moisture gets on the watch surface, wipe it off as soon as possible.
- Contact with a damp surface may cause the fluorescent color to discolor. Keep the fluorescent surface dry and avoid contact with other surfaces.
- Rubbing a surface with fluorescent paint against another surface may transfer the fluorescent paint to that surface.
CASIO COMPUTER CO., LTD. is not responsible for any damage incurred through the use of this watch, nor does it accept claims from third parties.
