These wall clocks use a "sweep" clock movement that operates very quietly and they require a small amount of simple assembly to place the hands on the face. The oval can be used horizontally or vertically and the Square can be twisted 45 degrees to be used as a diamond. Each clock face is unique, reflecting the grain of the wood it was made from. They can be easily decorated with paint, crayon or felt tip pens for a unique design. Printed paper or fabric can also be glued to the face for a different look.
