Electromagnet-driven wooden gear clock

Here's a little video featuring The Electra, another clock designed by Clayton Boyer. Like his other clocks, this one is made almost entirely of wood. What makes it unusual is that rather than being powered by a falling weight, it is driven by a hand-wound electromagnet. There is a shot in the video showing the magnet wire being wound around the core with the aid of a hand drill. Here is a photo showing the ratchet mechanism that moves the time train forward with every full swing of the pendulum:
