An AA battery operates the quartz movement on this clock set into a leather stirrup. I apologize to the horse men and women for calling this a stirrup if it's not, but i don't know my way around equestrian gear. City girl. This 7 1/2" x 7 1/2" clock hangs from a rawhide lace. The clock works and keeps good time. I can think of so many places where this would be a fun accent from an office to a stable to a Western themed family room.
