Maintenance and Care
Water Resistance
The Edillas Kids Digital Watch is rated 30M/3ATM waterproof. This means it can withstand splashes, rain, and brief immersion in cold water, such as during hand washing or playing in the rain. It is not designed for swimming, diving, or hot water activities. Avoid pressing any buttons while the watch is submerged in water to prevent water ingress.

Troubleshooting
