This small clock, with only two wheels, has the particularity of being driven by a solenoid that receives an electrical pulse every 5 seconds or so. The movable core of the coil transmits to the pendulum the necessary impetus to move for another 5 seconds. A micro-switch makes the electrical connection when the pendulum loses inertia.
It has a magnificent accuracy of a few seconds per month.
It works with a small 12 volt transformer.
