Hi Dave,
I am not going to be much use in answering your questions but I do know from experience the L&R waterless solutions work very well on clock movements. A guy that was teaching me used them and the results were very good. I am more of a clock fanatic but if ever I can comment with some useful info i will. wecome to the board (doing Bob’s job for him as he is lounging around in Mexico somewhere sipping cocktails no doubt 
). There are some watch experts on here so hopefuly they will stop being shy and post a response soon
Paul.
