There is auricular ornamentation consisting of ‘cartilage’, lobate rolls, and rows of little balls on the clock’s cartouche. This is the same décor that Ackermann used, together with the ends of little acanthus leaves (on the sides of the square of the clock), for the Simuna Church retable that was also in production in his workshop in 1684.

The ornamentation is attached to the background using forged nails. Analysis of the style used indicates that the sculptor who carved the parts of the clock’s cartouche that are in relief was the same sculptor with whom Ackermann worked on the pulpit at Karuse Church and the retable at Hageri Church.
