Important Information

Battery

The battery installed at the factory may be discharged during storage and shipping. Replace the battery when the indicator becomes dim, by visiting your CASIO dealer or distributor.

Water Resistance

This watch is designed to withstand water pressure at the indicated depth (50, 100, or 200 meters) under static conditions and is resistant to seawater. However, dynamic pressure generated by water movement (e.g., swimming, diving) is greater than static pressure. Refer to the table below for water resistance ratings.

Notes

1. This watch is not waterproof; avoid exposing it to moisture.
2. Do not pull out the crown while the watch is wet.
3. Do not press buttons or pull out the crown underwater.
4. Buttons can be pressed underwater, but do not press recessed buttons or pull out the crown. If seawater gets on the watch, rinse it with fresh water and dry thoroughly.
5. Suitable for diving (except for depths requiring a helium-oxygen gas mixture). Do not pull out the crown underwater.

Some water-resistant watches are equipped with a leather band. Do not wear such models while swimming or in any other situation involving immersion in water.

Precautions

• Do not attempt to open the case or remove the back cover.
• The water and dust-resistant gasket should be replaced every 2-3 years.
• If water or condensation enters the watch, return it immediately to your CASIO dealer or distributor.
• Do not expose the watch to excessively high temperatures.

General Instructions

• Although the watch is equipped with an shock-resistant mechanism, avoid strong impacts or dropping it on hard surfaces.
• Do not overtighten the band. A finger should fit under the band.
• Clean the watch and band with a soft, dry cloth or a cloth dampened with mild soap solution. Do not use volatile chemical solvents (e.g., benzine, solvents, cleaning aerosols).
• Always store the watch in a dry place when not in use.
• Do not expose the watch to aggressive chemicals such as benzine, cleaning agents, or aerosols. Chemical reactions can damage the gasket, case, and polish.
• Some watch bands have specifications printed on them. Be careful not to erase them when cleaning.
• For watches with plastic bands: A white powdery residue may appear on the band. This substance is harmless and can be removed with a wipe. If moisture is left on a plastic band or the watch is kept in a humid environment, the band may warp, crack, or tear. To preserve the plastic band, wipe off dirt or moisture promptly with a soft cloth.
• For watches with fluorescent bands and cases: Prolonged exposure to direct sunlight may cause the fluorescent color to fade. Prolonged contact with moisture may also cause fading. Wipe off moisture promptly. Prolonged contact with other wet surfaces may cause fading. Rubbing the fluorescent print with another surface may transfer the color.
