4. Water Resistance
The KXAITO 8087 watch is rated for 30M (100FT) Water Resistance. This means it is suitable for daily use and can withstand splashes or brief immersion in water, such as hand washing or light rain. However, it is not suitable for swimming, bathing, diving, or any prolonged water activities where it would be submerged for extended periods or exposed to high-pressure water. Avoid pressing buttons while the watch is wet or submerged to prevent water ingress.

5. Maintenance and Care
To ensure the longevity and optimal performance of your KXAITO 8087 watch, follow these maintenance guidelines:
- Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, strap, or internal components.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect its accuracy and water resistance.
- Impact: While designed to be robust, avoid strong impacts or dropping the watch, as this can damage the internal movement or external components.
- Battery: The watch uses a Japanese quartz movement. When the display dims or functions become erratic, it may indicate a low battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
