    Interesting lesson with the unites movement. A nice simple movement to work with. I think some might think do I have to know all this to become a watch repairer. Many members are clever with their hands but might find when it comes to maths it is too difficult. I hope it does not put members off.

    Sure.. so far the course has focused almost exclusively on the practical. For some faults, and to help with problem solving it does not hurt to know some theory too. ;)

    Oh, I really appreciated this video, it reminded me that I have to pay attention to the ratios. Very timely for me, as I am just working with a watch that has a power reserve issue, and the "turns of the barrel" discussion was a great nudge in the right direction about figuring out where the problem is. I'm pretty sure it's mainspring, but now I can verify. Just need to find a nice way to brake the train. Then if it is the spring, figuring out how to acquire an appropriate spring without spending twice what the watch is worth. It's a 70's Bulova, 11ANAC "do not open" barrel, automatic with an unusual scalloped inner barrel wall for the bridle. 

    Thanks!
