Mercury filled temperature compensated pendulum, open escapement. The pendulum includes two vials of mercury used to fight one of the biggest enemies of accuracy: temperature fluctuation. If it gets really warm, the mercury would expand upwards on the vials and compensate for that point of oscillation.
