5. Maintenance

5.1 Water Resistance

Your Casio AQ-800E-7A watch is water-resistant. This means it is designed to withstand splashes, rain, and brief immersion in water (e.g., washing hands). It is not suitable for swimming, diving, or showering with hot water, as steam can penetrate the seals.

• Do not operate buttons or the crown while the watch is wet or submerged.
• If the watch is exposed to saltwater, rinse it thoroughly with fresh water and wipe it dry.

5.2 Cleaning

To maintain the appearance of your watch:

• Wipe the watch case and band with a soft, dry cloth regularly.
• For stubborn dirt, use a soft cloth dampened with a mild soap solution, then wipe dry.
• Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish.

5.3 Battery Replacement

The watch is powered by an SR920W battery with an approximate lifespan of 3 years. When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and water resistance.
