Water Resistance

This watch is rated for 3ATM (30 meters) water resistance. This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water, such as during hand washing or car washing. It is not suitable for swimming, diving, or showering with hot water, as steam can penetrate the seals.
Care and Maintenance
Proper care will help maintain the appearance and functionality of your watch.
- Cleaning: Wipe the watch case and band regularly with a soft, dry cloth. For the silicone band, a mild soap and water solution can be used, then rinse thoroughly and dry.
- Mineral Glass: The watch features mineral glass, which is scratch-resistant. However, avoid harsh impacts or abrasive materials to prevent damage.

- Temperature: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect the movement and seals.
- Chemicals: Keep the watch away from solvents, detergents, perfumes, and cosmetics, which can damage the case, band, or seals.
- Battery: The watch uses a quartz movement powered by a battery. When the battery runs low, have it replaced by a qualified watch technician to ensure proper sealing and function.
