This is a Schatz “London Coach” 400 day clock that was made in September 1955. These beautiful clocks were very popular in the 1950s and early 1960s, in fact my parents and grandparents each had one that my uncle sent back from Germany. Most of them (including this one) have plastic panels in the case.
This one needed a movement overhaul and new suspension spring. I also polished and lacquered the case.
Here is a slideshow of more photos:
Repair job 5113. The movement is the Schatz miniature “53”. Horolovar back plate no. 1013A. Date code 9 55. This model normally uses a 0.0023 inch thick suspension spring and suspension unit 10A. This example needed a 0.0024 inch thick spring to keep time properly, and it had to be about 1/8 inch longer than usual to make the pendulum locking device work.
