It's funny, I actually do not care for the 6000 or the 6006 - or, for that matter, the 6007.
This is how I dress on a daily basis. I do not own any Brunello Cucinelli, which I do not particularly care for, but I do love my sweaters - particularly those from Inis Meian - and wear a lot of corduroy, tweed, etc. I am also partial to lighter colored neutrals, and often wear whites and beiges. I agree with your overall sentiment, it fits in very nicely with that kind of look. Clothing is, and always will be, my first love - with watches a very, very close second.
Your point about the 5226 is interesting, and it is one that I question as well - the 5226 is very of the moment and it is unclear to me how much staying power it will have.
Always appreciate your prejudiced ramblings!
