In the Horology Technology area, I have developed the basic techniques of watch repair. Including, but not limited to: basic assembly, cleaning and adjusting watch movements, case and crystal repairs, production of watch parts on lathe, operation of cleaning and testing equipment, and poising and truing of train and balance wheels. Advanced training includes escapement adjustment, repair of calendar, electric, electronic, tuning fork and quartz watch movements. Manipulative and technological skills developed during this course could be used in other technologies, such as micro mechanics, microelectronics and instrumentation.
