Just thought I would share this. So I've started watching my 5 dvd watch repair and servicing disks. The first one was based around proper tools and work area! Nice and informative. I started the second one last night. It is complete disassembly and they are using a Waltham size 18 lever type, a size 18 Elgin and a size 16 Waltham pocket watches. It is setup to disassemble along with the video. I've decided to just watch first and then hands-on later. Luckily I have both waltham types they are using and so far very very informative. I'm surprised that it starts with a FP pocketwatch as from what I've seen, these are the hardest to put back together. I've only gotten thru half disassembly right now but am really enjoying it. Very nice closeup work and of each individual part and its operation.
