Sinclair-I hear you, I have a few though I have down sized a bit. I am dreaming of the Ulysse Nardin(the name slips my mind) it isn't on there website its around 65k and I think its worth it, like you said in that range things only go up in value. I currently wear a Cartier Pasha C and enjoy it more then anything else I have had(Rolex, Tag, Bvlgari-big mistake!) Sounds as though you have impecable taste in watches, I like most all Pateks, Piguet. I want a JLC reverso duo very bad but need a new play watch first(enter Fortis, Cosmonaut-a very cool simple watch if your not familar with them) too many toys not enough money or time!! Do a search and just use the word "time" and the watch thread here will show it face(heh-heh), its name is "what time do you wear" a few others here are into nice watches.
