Actually, A. Lange did bring many innovations to the watchmaking industry, but you're correct in regards to extreme complications. Many of his innovations/patents were implemented by others throughout the years, and still used today. A. Lange's innovations lean more on the engineering of movements as opposed to the development of grand complications, etc... this was all back 170 years ago when precision was an extremely difficult feat. I think the sacred brands will remain as PP, VC, AL&S, Breguet, Cartier, JLC, AP, I might have forgotten a few... but not many others have even the remote possibility of breaking into that club; and it shows... if you look at their movements under a loupe, there's a world of difference in the craftsmanship that just can't be replicated (yet) by any cnc robotic machinery that's used by the likes of Rolex, Panerai, Omega, Breitling, Tag, etc... These days, there are quite a few brands coming out with extremely complicated watches... as well as the the newcomers building amazing mini machines like MB&F and Urwerk, Franck Muller; even Tag and Hublot are submitting their own complications for the sake of competition and marketing. To me, although there are some really cool engineering companies designing watches/movements these days, nothing compares to the very few from 150+ years ago when all they had to work with were hammers, chisels, and horses.
