Pendule de table mécanique

Comment ça marche

You wind the clock with a key on the winding arbor, which tightens a printed spiral mainspring inside the toothed barrel. As the spring unwinds, the barrel drives the centre, third and fourth wheels (a 195:1 train) up to the escape wheel. The anchor rocks against the escape wheel and is regulated by a pendulum, so the energy is released in small, even steps. A 12:1 motion work moves the minute and hour hands, and 12 ball bearings (608-2RS) on the arbors cut friction, because plain printed bearings would use up too much of the weak printed spring's torque. The review notes that the winding arbor still needs a hook to catch the spring's inner end, so winding is not yet working in this version.

The wheels, barrel and anchor sit on their bearings between the base and the front plate, which presses onto the pillars. The hands, dial ring and pendulum bob then go on by hand, with the bob screwing onto the rod.
