2 different watches, too difficult to choose for you, my friend. I'd say, personnally, go for the Perpetual Calendar, the IWC is a fine one, and you'll always have the time to get, after, the Breguet Chrono. but between the 2, the IWC pc is maybe, horologcally speaking, the more interesting, even if the esthetic of the Breguet is very fine... Just one question, which is in fact THE solution and THE answer...Which one speaks more to you? Best. nicolas, Co Devil...LOL
