This unique wall clock is designed to give the illusion that the numbers are floating. It combines the modern look of acrylic with the warmth of wood. The numbers and center accent are laser cut out of your choice of wood. The quartz movement is a continuous sweep movement, so it is completely silent. The movement is powered by a single AA battery (not included). Due to the nature of wood, each clock will be unique because of the grain of the wood. The wood comes clear coated to preserve the natural beauty of the species of wood selected for these clocks.
