5. Maintenance
Water Resistance:
Your watch is rated for 10 ATM water resistance. This means it is suitable for everyday use, showering, and swimming. However, it is not intended for scuba diving. Avoid operating buttons underwater.
Charging:
Regularly expose the watch to light to maintain its charge. The battery level indicator will show the current charge status. If the charge level is low, expose the watch to bright light until the indicator shows a sufficient level. The Power Saving function helps conserve battery life when the watch is left in the dark.
Cleaning:
Wipe the watch case and band with a soft, dry cloth to remove dirt and moisture. For metal bands, a soft brush can be used to clean between links. Avoid using chemical cleaners or solvents.
Sapphire Glass:
The watch features a scratch-resistant sapphire glass. While highly durable, it is not entirely impervious to damage. Avoid impacts and abrasive materials.
