but the case thickness doesn’t fit my wrist. 5270 wears much better for me. And you have two wonderful examples. I liked 5270J quite a bit but I also like the variants without tachymeter scale. And I wonder if I don’t prefer the two complications separately: as a chronograph I love my Cornes de Vache and as a perpetual calendar I think I would love the 3448 (I still have to see one in real life though).
