The Golden numbers are assigned to this position, which determines the date of Easter, in consecutive order). There are seven additional calendar specifications.
The history of monstrance clocks
Most monstrance clocks were ordered by high members of the clergy and are therefore always unique pieces of great value. A draft of the design had to be made; more requirements included hour and quarter hour strike, alarm, verge escapement, and many other indications. Apprentices usually had no money and often indebted themselves heavily for their masterpiece, especially since the making of a unique piece also required the appropriate special tools. Since such a clock quite easily cost the equivalent of four times the annual salary of a senior civil servant at the time, wealthy buyers were extremely sought-after.
