I made this as my senior project for high school. It was a partial reconstruction of a watch I owned. I created a version without the movement for use with the 3D printer. This version has a partially created movement.
The gears and movement would not actually work, they are not the proper gear types (cyloidal). I created it for show and to understand the watch better, not all of this is exact. There are many more pieces to an actual watch movement.
