3d printed watch

I thought it would be interesting to build a compleatly 3d printed watch, so I made this model. The model is just a base to build on, and it does not have a motor designed into the system, but the math behind the gears is right. The simentions are 47 mm in diameter and 10 mm in height. The gears are 52 teeth for the outer gear, 26 teeth for the middle gear, and 4 teeth for the drive gear. I'm not 100% sure that the madul as a whole works, so all comments are helpful.
