As others have said it’s because the Lange actually has traditional lugs which the other two don’t. Right now, this doesn’t look right to many people (that may change).
It may very well be that after some time, as we get used to seeing it, this Lange workaround for perceived integration will not look so odd to us.
I would argue for the same reason a Nautilus on a strap also looks somewhat odd, although less odd as the years go by.
