Maintenance

1. Water Resistance

Your Casio HDC-700-3AV watch is rated for 100-meter water resistance. This means it is suitable for swimming, showering, and snorkeling. However, it is not suitable for scuba diving. Do not operate buttons while the watch is wet or submerged.

• Avoid exposing the watch to hot water or steam, as this can damage the seals.
• After exposure to saltwater, rinse the watch with fresh water and wipe it dry with a soft cloth.

2. Battery Replacement

The watch is powered by a single Lithium Metal battery. While designed for long life, battery replacement should be performed by a qualified technician to ensure water resistance is maintained. Do not attempt to replace the battery yourself.

3. Cleaning and Care

• Wipe the watch case and band periodically with a soft, dry cloth to remove dirt and moisture.
• For resin bands, you can use a mild soap solution and a soft brush, then rinse thoroughly and dry.
• Avoid exposing the watch to strong chemicals, solvents, or detergents, as these can damage the resin materials.
• Store your watch in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
