This Chevy flexplate clock made by clock9nine is made from a real flexplate that fits Chevy vehicles. It has been outfitted with a 3d printed face, and custom designed 3d printed components to allow the gear to rotate. This clock is huge! See the photos for comparison to the Chevy small block clock. This is the rotating version of the flexplate clock. To see the non-rotating gear version, see here: https://www.etsy.com/listing/1109375465/large-wall-clock-flexplate-from-chevy?ref=listings_manager_grid Free shipping within the US! This clock is not silent like the rotating timing set clocks we make. It has a slightly larger motor to power the 14" diameter gear. The continuous clock mechanism runs off a AA battery (included) and the gear rotation runs off a 110v wall plug. The wire has a rocker switch on it. It is recommended that you turn off the motor when you are not around to enjoy it. The motor will last longer this way. The clock will still maintain time while the gear rotation is shut off.
