As the art of making clocks became more widespread and distinguished, guilds specifically for this trade emerged around the sixteenth century.
One of the first guilds developed in London, England, known as the Worshipful Company of Clockmakers; the group formed after a small number of foreign-trained clockmakers spent time working in London.
Clockmakers generally do not work on watches; the skills and tools required are different enough that watchmaking is a separate field, handled by another specialist, the watchmaker.
From the beginning in the 15th century through the 17th century, clockmaking was considered the "leading edge", most technically advanced trade existing.
Early clockmakers fashioned all the intricate parts and wheelwork of clocks by hand, using hand tools. The Temple of the Great Clockmaker, in the novel The Case Of The Dead Certainty by Kel Richards, is a temple which represents deism.
