An excellent primer. Contains all information necessary to get you started. Even if you already have some experience in watch disassembly, the course is well worth your attention, as it introduces clarity and order into these fundamental concepts. The material is delivered with calm professionalism, and well illustrated with example. One thing I cannot stress enough: heed Mark’s advice and buy the equipment of quality as high as you can afford. I would recommend buying fewer tools, but of higher quality. Otherwise you will have to make the investment twice as you find that some of the tools you ordered come pre-broken.
