Steampunk Pendulum Timer

Using a combination of Technic, Bionicle, and regular Lego, this is a fully functional and operational pendulum timer. Powered by a pullback motor and regulated by a pendulum, this timer has an accurate second hand (with a 60 second sweep) on top, and an accurate minute hand (with a 12 minute sweep) on the bottom.

We have had the timer run for up to 20 minutes on a single wind... how long can you make it go?

If I can post videos to show the escapement, winding mechanism and gearing action then I will do so.

Finished with a steampunk look, this is the timer you never knew you wanted... but now you know you need.
