Both are great, but the 3337BB is my choice. Hard to add more Breguet DNA to a wristwatch. And the engraved movement with the sapphire back is the cherry on the cake. ❤️ I think also the 36mm are nice and its gorgeous dial gives a lot of presence on wrist.
I am chasing one and first thing I would do, is to change the folding-clasp against a Breguet buckle.
