Narrowed down my Sinn choice to three. The 856 and 857 I can buy new. Probably go used for the 756. Not crazy about a lack of permanent seconds on the 756, but after thinking about it, don't see why I couldn't get used to it. The 857 is my shakiest bet here, simply because I really don't like to go bigger than a 42mm... However at 12.2 thick, it shouldn't be a very bulky watch... As for aesthetics... Well, they're all damn pretty. Which do you think is sexiest?
