Maintenance and Care
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, a slightly damp cloth can be used, followed by drying.
- Water Resistance: This watch is water resistant to 30 meters (3 ATM). This means it is suitable for everyday use and can withstand splashes or brief immersion in water. It is not suitable for swimming, showering, or diving. Avoid operating buttons while the watch is wet.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect its accuracy and lifespan.
- Chemicals: Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the case, band, or seals.
- Battery: The watch uses a standard watch battery. 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.
