“This clock was made from a recycled aluminum bike wheel. The wheel mounts directly to the wall through the hub using a hollow wall anchor and gives the illusion that it is floating off the wall. The clock movement is a high torque German quartz movement and is attached to a set of rear cassette gears to conceal the movement. The movement is attached to the wheel by hanging it off of a screw coming out of the hub, and runs on 1 AA battery, included.”
