This is a basic model of a swiss lever escapement, it could also be used as a desk toy.

I have always been fascinated by the inner workings of a mechanical watch, I have designed this model to understand the basics of how a watch regulates it’s speed. The model’s parts are very easy to print and uses common fasteners to hold everything together.
