Great course on fault finding
In this course, Mark presents what appears to be a very sensible approach to fault finding, including a pre-service screening protocol. He does this in a clear and organized way, with the help of excellent video material, showing the smallest details. I have serviced a couple of movement after finishing the course, and I have noticed that I am now a lot more observant, inspecting and testing things to a larger degree.
Much of the course is devoted to theory lessons, with explanations of the mechanics of the different parts of a basic mechanical movement, not least the escapement. This is of course very import knowledge when fault finding, but If you already know the details of how a watch works you may find this information to be a bit superfluous.
All in all, I am very satisfied with this course and I’m looking forward to level 4.
