Schatz introduced their 1000 day clock in 1954. This round model first came with a glass dome, then was changed around 1956 to a platic dome with locking tabs. The first movements had straight legs, and were changed to the more graceful curved legs around mid-1955. The round base model came with several different styles of decoration above the dial. Most of the dials have small radial Roman numerals, but a few have small upright Arabic numerals.
