Carlos Diaz was head designer at F.Muller before he co-founded R.Dubuis in '99, or so I was told then (pls correct if wrong). Thus the obvious bridging of genes between the two - design wise at least. Agree with the size thing, it's getting ridiculously large now - think Panerai Egi! ;p. But believe it will (hopefully) eventually revert back, with 42-44mm being the sweet spot for gents' watches, imo.
