5. Maintenance
5.1 Cleaning and Water Resistance
The RUIMEN Smartwatch is IP68 water-resistant, meaning it can withstand splashes, rain, and brief immersion in shallow water. You can wear it in daily life, such as when washing hands or during light rain. However, please do not immerse the watch for extended periods, wear it while swimming in the sea, or expose it to hot water (e.g., hot showers, saunas), as this can damage the device.
To clean your smartwatch, gently wipe it with a soft, damp cloth. For the silicone band, you can use warm water with a mild dish soap solution. Regular cleaning helps prevent skin irritation and keeps the watch looking new.
