Thank you for the kind words! To tell the truth, I was more impressed with the fact that I didn't mess up cutting the new stem. I couldn't understand why it would be so difficult to put the watch back together - and then I saw the experienced watchmaker who has the entire watch in one pile (not really a pile) in front of him. That - would take me a very long time to sort out. I very carefully separate the pieces into individual watchmaker cases based on the removal step. So the correct screw stay with the correct bridge, etc. I've attached a pic of the bumper when it was disassembled. That, and lots of pics showing spring placement, location of screws of different lengths, and I managed it ok.
In fact - it was a lot of fun. My wife tried to get me to act in amateur theatre once, and I really prefer working on a watch by myself to being on stage!!
Thank you again for your very kind words!
