Guilds
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. A requirement of joining the guild was to practise their craft and gain as much experience as possible, along with joining one of many other trade guilds, such as the Blacksmiths, Stationers, or Drapers Company. There are many guilds where clockmakers meet to buy, sell and get clocks to repair from customers, the IWJG is one of the most prominent in the world.
