Thanks Freddy, I think 36mm is ok, not too small for modern wrists and with a more straight forward design of the datejusts / explorers they wear quite well. I think the plain bezel and no date or cyclops of the explorer helps make it wear bigger.
I actually have an old gen Seamaster 34mm and it wears just as big as a Datejust because of the dial size and the thin case profile.
