This Piston Desk Clock is one of the very rare pieces in a 12-piece exclusive edition. Created with a piston from an actual flying and formerly active Cessna 402 airplane, this desk clock features a modern industrial look. The material that came from the aluminum piston of the Cessna's propeller was sanded and machined at a 70-degree angle. The clock measures 4" in diameter and 2 _" in height. The clock face is 3" in diameter. This product is available in three Miami Beach colors: pink, orange, and white.
