The outstanding feature of the high-rise building and thus the landmark of Augustusplatz is the striking mechanism on the roof, consisting of three bells cast by the bell foundry Schilling & Sons in Apolda (restored from 2001). The bells are struck by two 3.30 m tall bell men - which were then considered to be the largest tower striking mechanism in the world. The bell beater sculptures are by Joseph Wackerle. In 1927, the Edwin Werner company from Leipzig was responsible for building the substructure of the belfry and the bellmen on the "Krochhochhaus" building on Augustusplatz.
Below the bells is the Latin inscription OMNIA VINCIT LABOR (Everything overcomes [work]). Below this is the display of the phases of the moon flanked by two lion relief representations, which take up the entire front part of the 12th floor, so there are windows on the 12th floor only at the back of the building. The 11th floor also has only two windows instead of the 3 used on the other floors, between which there is a tower clock with a dial of 4.30 m in diameter. The clock was made by the Leipzig company Bernhard Zachariä GmbH, the world's leading manufacturer of tower clocks at the time.
