- Watchmaker is an artisan who makes and repairs watches. Since virtually all watches are now factory made, most
modern watchmakers just repair watches. However, origionally they were master craftsmen who built watches, including all their parts, by hand. Since modern watchmakers are required to repair older watches for which replacement parts may not be available, they must have some fabrication ability. A skilled watchmaker can typically manufacture replacements for many of the parts found in a watch.

A watchmaker, as the name implies, works primarily on watches, not clocks, the latter is called a clockmaker. Some watchmakers work on clocks, but the skills and tools needed to work on a watch are not always applicable when working on a clock.
Historically, in England, watchmakers would have to undergo a seven-year apprenticeship and then join a guild, such as the Worshipful Company of Clockmakers in London, before selling their first watch. In modern times watchmakers undergo training courses such as the ones offered by the BHI, or one of the many school around the world following the WOSTEP style curriculum. Some USA watchmaking schools of horology will teach not only the wostep style including the ETA range of movements but also focuses on the older watches that a modern watchmaker will encounter on a daily basis.wikipedia
