Query: Great Concept...broke within 24 hours

The watch had a great concept and my daughter loved the design. She was able to quickly put her kindergarten level time telling skills to work. Sadly, the watch broke within 24 hours. The hands completely stopped moving. We tried to replace the battery but that didn't work. Not a very durable product which is sad because the concept of the watch makes it most appropriate for the Kindergarten to second grade level age child.
