Love it, IFssr. That is a perfectly done timepiece, in the best materials possible for that version.
There are more than a few AL&S owners here.
My Datograph is one of my most treasured possessions.
AL&S fly so far under the radar of most people's understanding of what makes something truly great, that I avoid even speaking about watches with most others.
They do "the elegance of simplicity" extremely well. Used to live in Germany, so this is a nice reminder. I really like the Lange 1, but may go for the steel GO Panograph instead to save some coin. SWMBO is getting a little concerned how first the custom bikes, now the watches seem to multiply.
Nice little ALS movie here if you haven't seen it already: http://www.hodinkee.com/blog/20-years-of-lange-video
