pclfal, The easiest way that I was able to do the Hermle movements was to take a lot of pics. Front, back, top and sides. Most of them I have taken the floating balance off first and soaked it in one dip for 10-15 min. If you set the movement up to where it has finished striking the 3/4 hour, then mark the wheels on the back and the barrel on the bottom before you take it apart, it will take a lot of the frustration out of setting it up when putting it back together. You may already know all this, I never thought to ask
