A watch movement (also known as a "calibre") is the inner mechanism of a watch which powers its functions. It is typically composed of gears, springs, and other components that control the timing of its hands or display. The three main types of movements used in wristwatches are mechanical, automatic and quartz.

There are basically two paths to becoming a watchmaker; going to school or winning yourself an apprenticeship. Both have their pros and cons and the only right choice is the one that's right for you. With apprenticeships, the biggest hurdle, at least in the beginning, is finding someone willing to take you on.
