And the name on the dial? Hermann Horrmann was a watch retailer in Leipzig, Germany, founded around the turn of the
link 20th century. Wall clocks and watches of various brands, most signed solely by the retailer on the dial, can be found and collected today. Given the location, Hermann Horrmann-signed watches are not found after 1945. This rabbit hole led me to a crazy German watch forum post where the descendants of Horrmann started chiming in with info and family photos!
