You have a nice problem here.....
Both classic watches, though not both with classical styling. Each an icon.
I have owned both of these watches, and sold both of these watches. The one I regret selling more is the 1815 Chrono (though I am also a big Lange fan).
if you are after a rare indie piece, obviously the answer would be the VH GF. 1815 a more "stable" piece in regard to its status as a wonderful dress chrono, and ease of use and service.
