This midget 400 day clock was made by Koma (Konrad Mauch) in Germany in the late 1950s. It is 7 1/16 inches tall (to top of finial) and 4 11/16 inches wide. The dial diameter is 2 15/16 inches (including bezel). The pendulum on this clock turns much faster than that on many 400 day clocks - 15 oscillations per minute). By comparison, standard size 400 day clock pendulums make 8 rotations per minute, and the Kern miniature makes only 6 oscillations per minute. Horolovar back plate no. 1393B. Suspension unit similar to 38 but uses smaller fork. Suspension spring .0022 inch thick
