Battery Information

Your Casio MW-620H watch is powered by a Lithium Metal battery, designed to provide approximately three years of power for both movement and the LED light function. When the battery runs low, the watch may exhibit irregular operation or the LED light may dim. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and water resistance.

Operating Your Watch

Basic Timekeeping

The watch displays time using analog hour, minute, and second hands. The date is displayed in a small window on the dial.

Using the LED Illuminator

To illuminate the watch face in low-light conditions, press the button located on the side of the watch case. The LED light will activate, providing clear visibility of the dial. The afterglow feature ensures the light remains visible for a short period after the button is released.

Water Resistance (100M)

Your Casio MW-620H watch is rated for 100-meter (330 feet) water resistance. This means it is suitable for everyday use, including hand washing, rain, showering, swimming, and snorkeling. It is not suitable for scuba diving or high-impact water sports. Important: Do not operate the crown or any buttons while the watch is wet or submerged in water, as this can compromise the water resistance.

Maintenance

Cleaning Your Watch

To maintain the appearance of your watch, wipe the case and band with a soft, dry cloth. For resin bands, you may use a mild soap solution and rinse thoroughly with water, then dry completely. Avoid using harsh chemicals or abrasive cleaners.

Battery Replacement

When the battery requires replacement, it is strongly recommended to take your watch to an authorized Casio service center or a reputable watch repair shop. This ensures that the correct battery type is installed and the watch's water resistance is properly maintained after the case back is opened.

Water Resistance Care

To preserve the water resistance of your watch, avoid exposing it to extreme temperatures (e.g., hot showers, saunas) or sudden temperature changes. Have the gaskets checked and replaced periodically, especially during battery changes, to ensure continued water resistance.

Troubleshooting

• Watch is not running: The battery may be depleted. Refer to the 'Battery Replacement' section.
• LED light is dim or not working: This is typically an indication of a low battery. Replace the battery as described in the 'Battery Information' section.
• Time is inaccurate: Ensure the crown is fully pushed in. If the issue persists, the battery may be low, or the watch may require servicing.
• Moisture inside the watch: If you notice condensation or moisture inside the watch, stop using it immediately and take it to an authorized service center for inspection.
