Above on two concentric dial rings are the solar calendar (1-30, gilt) and the lunar calendar (1-29); in the center on the right is an aperture for the phases of the moon. Below on the smaller dial there are a gilt chapter ring with Roman numerals for the hours and an alarum disc with Arabic numerals. The bell is screwed to the base.
