... I've read. I was about to sleep, now gonna need some pills

Just a little comment about the pushers, because for me too, its critical. When you trigger the chrono, the pusher goes from soft to harder untill you reach the breaking point. The magic is in the smooth feel of the whole process. Why? This is what tells you the most about the royal movement. The reset is the most magical reset of all chrono's i've ever tried.
The way the teeth of the wheel are designed, you got the sweet linear start of the chrono, the linear run,... Basically you can take any other chrono, there's no match.
I was at my AD comparing it with the dato up/down. We are mot even close. Just the finished and the beauty of the movement of the Lange is outstanding, but mechanically wise are too far IMO.
About the design, i'd say its coherent with what it wants to be. In that way, job accomplished. If you ask me, it has a strong Design in the classical style.
Thanks again for this outstanding post !
