My first thought, though, was, 'You clearly love the calendars, so sell the Breguet.' But it's got that gorgeous direct simplicity none of the other have! My second thought was, 'Don't keep the annual when you've got a perpetual right next to it.' But the Lange is the most beautifully finished in the group, feels the most valuable in the hand, regardless of the actual cost. My third thought was, 'You've got two Pateks here, give up the lesser of them, so that's the 5212' but, of course, that watch has delightful quirks and is the most casual of the bunch.
