Maintenance and Care

Water Resistance

Figure 3: The watch is water resistant up to 30 meters.

Your LILUOKE LK90series watch is water resistant to 30 meters (3 ATM). This means it is suitable for daily use, splashes, rain, and brief immersion in water. It is not recommended for swimming, diving, or prolonged water activities. Do not operate buttons while the watch is wet or submerged.

General Care

• Clean the watch regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying.
• Avoid exposing the watch to extreme temperatures, direct sunlight for extended periods, or strong magnetic fields.
• Keep the watch away from chemicals, solvents, and detergents, as these can damage the case, strap, or internal components.
• Ensure the crown is always pushed in completely to maintain water resistance.

Battery Replacement

The watch uses 1 LR44 battery (included). When the digital display dims or the watch stops functioning, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and water resistance.

Troubleshooting

• Watch not functioning: Check if the battery needs replacement. Ensure the crown is fully pushed in.
• Digital display dim or blank: Battery may be low or depleted. Replace the battery.
• Time is inaccurate: Re-set the time following the "Setting Analog Time" and "Setting Digital Time and Date" instructions.
• Water ingress: If water appears inside the watch, stop using it immediately and seek professional repair to prevent further damage.
