so what strikes me about this list is the huge price range, the Breguet lists at 4x of the Doxa...
So that in mind, and also the fact that you want absolute durability, I'd drop the Breguet. Don't get me wrong, it is a very nice watch, but unless you really are in love with it, and if you were you wouldn't ask us

, I don't think the aded cost is worthwhile. Also no matter how well made, a chrono just has a many more places for failure, both in the movement and in the case.
