model and the dial color which I understand is not interchangeble by Lange.
I like the Dato in PT for the weight and the understated nature of it and its "I know its PT and that's enough" overall feel and experience.
I like some of their pieces in their RG as I find their shade of PG darker than say that of LUC and Breguet for example and that appeals more to my eye.
But if the overall look and dial color is neutral to PT, that remains my favorite precious metal.
