thanks for your input..actually I'm quite a simple person..
I know you can further dissect each complication down to sub groups but as long as I have one of those complications it will do..
I'd then go through the subsequent criteria for that complication such as technical excellence of the calibre, finishing, horological accuracy, looks, authenticity of manufacture, …I'm bound to filter out a lot by then…
Once I buy a certain complication, if another new model came out, I'd just ask myself a few simple q's.. is the newer model any more special in complication, has more refined finishing, more accurate, more exclusive, had newer technology than what I already have in hand… if not.. then the new model wouldn't be any temptation at all..
For me if I had to choose between the 2 chronos you highlighted, its a no brainer for me.. I'd go for the Lange anytime...
I'm not much of a vintage person as I want maximum horological performance with the finest finishing and latest hi tech hi performance materials, as far as possible and in as few numbers of production as possible….History to me is for us to avoid making the same mistake twice but the future is where we should be heading to....
I know this is not everyone's opinion… I wouldn't pay any premium for a vintage or antique whether it be…watches, cameras, furniture, Ming vases, etc...I'm more of a 'bawah' rather than an 'atas' person..
...
Hehe ... this complication theme won't work. It would get out of hand very quick. Don't believe me?
Here's the problems
Chronograph
a) Movement
1. Column Wheel
2. Cam lever
b) Dial design
1. One register
2. Two register
3. Three register
c) Function
1. Normal non-flyback
2. Fly back
3. Rattrapante (split seconds)
4. Feudroyante (lighting seconds)
d) Operation
1. One button non-coaxial with crown
2. One button coaxial with crown
3. Two buttons
Not to mention in house or not in house, auto vs manual, vintage vs modern
You see the problems 
Looks at these photo and tell me which one should I choose. A super finish column wheel chrono or a historic NASA moon watch.


My head hurts just trying to decide.
