I recently repaired this square dial Schatz 400 day clock made in November 1953. I cleaned the movement, polished the pivots and the anchor pin, and replaced the suspension spring. These clocks use a 0.004 inch thick Horolovar suspension spring. I also polished and lacquered the base and pillars. The square dial clock is not as common as the round dial model.
Repair job 5518.
