Children enjoy racking their brains and making calculations in a playful way. The Albert clock is exclusively for kids. It is a brain teaser. It displays numbers but it also requires solving mathematical equation in order to read the time. The top displays a single equation for the hours while the bottom has another equation for the minutes. Albert Clock features a universal adapter design for use in any country. In addition to the unique equation layout, the Albert Clock has a minimalist design with simple lines and a study frame.
