The outer part of the upper leaf engraved with a depiction of a hound wearing a collar; the interior engraved with a depiction of a rose and calibrated to the edge for common hours comprising 6-12-6. The lower leaf is inset with a compass bowl with etched steel needle and engraved with an arrow marking the orientation of magnetic declination; the edge calibrated 4-12 and 1-8. The exterior of the lower leaf with later engraved decoration in a naïve, folk art style.

Diptych sundials with integrated compasses were first introduced in the 15th century, although this example follows a type produced in Nuremberg from the mid-16th century onwards. The ingenious inclusion of a compass allowed these sundials to be used anywhere, as once the instrument is correctly aligned it will provide an accurate reading.
