Casio Watch Instruction Manual

Introduction and General Information

Attention: The owner, user, and anyone who will use the watch should read this manual carefully. Casio watches comply with water resistance specifications and are designed for everyday use, such as washing hands, in rainy weather, and swimming. They are not intended for scuba diving or other water immersion activities that may subject the watch to stronger vibrations or pressure.

Brand: CASIO

Water Resistance Levels

Casio watches are rated for different levels of water resistance. It is crucial to understand these ratings to use your watch appropriately and avoid damage.

Note: Water resistance is not a permanent condition. Seals and gaskets can degrade over time due to normal wear and tear or exposure to environmental factors. It is recommended to have the watch's water resistance checked periodically by an authorized service center, especially if the watch is frequently exposed to water.

General Care and Usage Guidelines

• When the watch is wet, do not operate the buttons or the crown.
• If the watch is exposed to salt water, rinse it with fresh water and dry it thoroughly within 2 to 3 hours.
• Avoid exposing the watch to strong magnetic fields.
• Do not expose the watch to chemicals such as solvents, detergents, or insect repellents, as they can damage the watch's casing and band.
• Do not subject the watch to extreme temperatures (e.g., do not leave it in a hot car or expose it to direct sunlight for extended periods).
• Clean resin bands with water and mild soap, then rinse thoroughly. For metal bands, clean with a soft cloth and mild detergent, then rinse and dry.
• Do not attempt to open the watch case or disassemble the watch yourself.
• If the watch is exposed to water, check the seals and gaskets. If they are damaged or worn, they should be replaced by a qualified technician. This includes checking the crown, buttons, and case back.

Specific Watch Functions
