Nicolas -
Thanks for reviving this one. It is one my my favorites, along with the other two you mention, the LM Anniversary and the RL. One minor note: I believe the original Lange deck watch had a PR of 40 hrs.
The dial is very well done. Do you know if it is printed or engraved (like the GO Senator Chronometer)?
Lange chose to update two significant parts of the watch: the hands aren't the poire hands of ship's chronometers, and of course the automatic movement. As with almost all of Lange's design decisions, I feel these changes work very well and go beyond mere "change for change's sake".
