Miniature 400 Day Clock by Edgar Henn

This miniature 400 day clock is 8 1/4 inches tall without the dome. There in no name on the face. The back of the movement is labeled “Euramca”. The movement was made in Germany by Edgar Henn, and the “Horolovar 400 Day Clock Repair Guide” classifies this movement as plate 1088. It was made around 1953.

This clock uses suspension unit no. 29B, with a .0023 inch thick suspension spring. This clock ticks slower than the standard 400 day clocks, making only 7.5 beats per minute (8 beats in 64 seconds). Standard 400 day clocks by Kundo and Schatz make 8 beats per minute, and their miniature clocks make 10 beats per minute.

This video shows the remarkably large pendulum rotation on this clock, just over 1 1/2 turns when fully wound!
