5711 because this is the Patek forum 😇 Forum aside and from the photo, the AP seems to have stronger wrist presence. IMO although both are iconic, my choice would be the 5711 because the pothole shape is more unique
Like the two models. AP has lovely curves on the slightly plump side. But the 5711a more better proportions. Nicer body. And perhaps much preetier refined face. 👌 Geross.
