Hi,
I am trying to understand where you want to go, here is my understanding (I am not a psychatrist!...) but we all go through the same thought processes trying to justify or bring some pragmatism or some reason to a passion!...
So my interpretation is you are looking for and can afford something exclusive, ok that's good, so you're right go for it! Now to me if I look at your list I can see only exclusive watches but which I would classify into 2 groups:
1. Prestigious: if this is what you are looking for, I would agree with my friends, I would go for Lange or PP. These are definitely exclusive, refined, have the advantage of great reliability, guaranteed service in the long run and value keeping, if not value gaining in the long run.
2. Esoteric: well some in your list I don't even know which can be a good or a bad sign depending on what you want. With these beasts you are sure to go for something different but non of the points above apply...
I hope this helps, if I was in your position I would first complete my collection with a Lange or a PP, then you can go to independant watch makers, and if you really want to push it, get in touch directly and have one made just for you as a Pièce Unique!...there is no limit...my friends suggest De Bethune, why not but there are plenty of other possibilities, the more you search, the more you find, why not De Witt, Parmigiani...
I hope this helps, anyway, there is only one thing that matters, have fun and your choice will be the best!...
My personal psychatric analysis, since I cannot afford some of the beauties you are after (or not yet!...) lead me to a combination which I would describe as exclusive affordable vintages, which is an equation that takes time and thinking to solve but gives me a lot of pleasure...
Have fun and enjoy your watches...
Matt
