This is a watch for family in case of the missing of child. When missing the children, the parents will be very anxious and overwhelmed. And as child care, it is easy to lose the attention so that bad guys can take the opportunity to take the boy. So we designed this watch which uses radio wave as signals for family members. When the child missing, parents can use the airmanship by color .When parents and children getting closer, the light will be more intense. Meaning family heart to heart.
