In the central section of the clock is an Astrolabium with the "actual" clock, which shows the phases of the Moon and the locations of the planets.

The upper half of the dial contains a Latin inscription: In hoc horologio mobili poteris haec aliaque multa dignoscere:… (In this moving clock you can see these and many other things:)
"The equal and unqual hours, the central process of the planets, the ascending and descending signs of the zodiac, and in addition the ascensions and descensions of the fixed stars.
Windows on each side of the dial show where each planet rules.
Above is the adoration of the Three Kings, below is the Kalendarium with the movable feasts."

In the spandrels at the corners of the dial are depictions of the Four Evangelists – instead of the depictions of the Four Astronomers found on many other astronomical clocks.

The dial is flanked on left and right by two planetary tables.
