Coup Perdu Clock Second Prototype

Progress update for a 3D printed desk clock with a Coup Perdu escapement.

The first early prototype is shown here https://youtu.be/9kx7PNscmgY

This update shows the nearly completed clock design. Everything is fully functional. The clock rewinds every few minutes using a small N20 motor and two AA batteries. Estimates are a runtime of around 6 months. There are a few cosmetic issues to clean up before the design can be released on MyMiniFactory. Primarily, the wiring needs to be improved and the batteries hidden in the base.

Coup Perdu is French for "lost beat" meaning the escapement moves only once during a complete back and forth motion of the pendulum. This allows the second hand to move 60 times per minute with a 1/2 second pendulum length.
