Maintenance and Care
Water Resistance (50M / 5ATM)
The Dayllon Kids Digital Watch is designed with 50 meters (5ATM) water resistance. This means it is suitable for:
- Hand washing
- Splashes and rain
- Showering (cold water only, avoid hot water)
- Swimming in shallow water
Important: Do NOT press any buttons while the watch is wet or submerged. Avoid using the watch in hot water, saunas, or during diving activities, as this can compromise the water seal.

Cleaning and Storage
- Clean the watch regularly with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth and then dry thoroughly.
- Avoid using chemical cleaners, as they can damage the watch's materials.
- Store the watch in a cool, dry place away from direct sunlight and extreme temperatures.
Battery Replacement
The watch uses 1 AAA battery. When the display dims or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified technician to ensure the water resistance seal is maintained.
