Join AWCI for this course which explains the inner workings of a watch. It is a must for anyone considering taking the CW21. It allows you to understand not only functional issues, but theoretical ones as well. Lubrication, isochronism, automatic systems, calendar systems, and much more will be covered. Tests will be given at the end of each section, with answers reviewed. A great way to learn and practice theoretical test taking.
No prerequisites for the class. Highly encouraged to own a copy of The Theory of Horology.
