I just repaired this Schatz 1000 day clock made in February 1955. This is the round model, and this one is old enough to have a glass dome (the plastic dome model have an extra piece on the base to engage the dome’s locking lugs).
I polished most of the brass pieces, and installed a new old stock dial.
Repair job 6070. The movement is Horolovar back plate no. 1010. It uses a .0024 inch thick Horolovar suspension spring. I polished the pivots. I find that polishing the barrel pivots on the barrel arbor helps these clocks to run better.
