Easy to Learn and Teach: This is a professional wall clock for children's learning. Each quarter is divided into a specific color, so children can easily learn terms like \"0' clock 00\", \"Quarter past\", \"Half past\", and \"Quarter to\". In addition, the 5-minute intervals around the outside can provide great help in telling the exact time. Early Childhood Development: We designed the clock to help when teaching our own child to learn to read the clock. For children to learn the clock effectively, our design must be easy to understand; marking each quarter with a different color would give your child an opportunity to quickly create an association between the numbers and where they are. Studies show that certain colors greatly affect a child's mood. Every detail of this clock has been optimized to have a strong learning effect. Silent Sweeping Movement: This analog wall clock for children has a robust, durable design and a high-quality silent sweeping movement, saving you and the rest of the family from the annoying ticking sound. The silent design is also great for classrooms, as it keeps distractions away! Long Battery Life: The low-power quartz movement requires one AA battery (not included), preferably use a regular carbon battery rather than an alkaline battery, which can work for a long time and with good time precision.
