Maintenance

Cleaning

To maintain the appearance and functionality of your watch:

• Wipe the watch with a soft, dry cloth to remove dirt and moisture.
• For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent. Avoid harsh chemicals or solvents.
• After exposure to saltwater, rinse the watch thoroughly with fresh water and dry it completely.

Battery Replacement

The watch uses one LR44 battery. When the battery power is low, the display may become dim or the backlight may not function correctly. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance is maintained.

Storage

When not in use for extended periods, store the watch in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing it near strong magnetic fields.

Troubleshooting

• Blank Display: Check if the battery needs replacement. If the battery is new, try performing a full reset (refer to the watch's specific module manual for reset procedures, often involving shorting a specific contact).
• Incorrect Time: Re-enter the time setting mode and adjust the time and date as described in the Setup section. Ensure the correct city code and DST setting are selected.

• Water Inside Display: If condensation or water droplets appear inside the display, stop using the watch immediately and take it to an authorized service center for inspection and repair to prevent further damage.
