At your Breguet AD first. I was actually looking for a Aeronavale as well since I don't really need the date and it is closer to the original Type XX. What I realized only when seeing both watches side by side is that the dial is very different beside the date. The Aeronavale features a Matt dial and printed white indexes while the Transatlantique has a shiny black dial and applied steel indexes. Of course, the hands are different too. Maybe you are already aware of this but I wasn't at the time.
