... 48,x mm without crown, but more important is the mesure from lug to lug
and if you look at the case with it's short lugs is nearly the same mesure there from lug to lug,
so that these monsters are friendly monsters, even more as most people believe,
on a wrist.
Also there coloured hands make them seems to be friendly, so no reason to be afraid of these "monsters".
