It's never really occured to me. I figure that collecting anything costs money, and I either have enough for a piece, or I don't (mostly the latter ) Even though I'm still building my collection, I'm trying to keep it reasonable: I stick to one brand which I like, and am trying to use the discipline of a daily beater, and others to then alternate to depending on situation. That allows each watch to have it's day, rather than just gathering dust as a paperweight due to not being able to take off a beater I figure that way, I'm not simply buying for the sake of buying (well, not too much )
