Lange changed the dial color on this model several years ago, long after they changed the "advance-everything-by-one-day" pusher from large/rectangular/protruding to small/round/recessed. All pieces with the rectangular pusher should have the older dials (unless the owner got Lange to change the dial years after purchase). Some pieces with the recessed pusher (the earlier of those pieces) have those same older dials, while the more recent pieces with the recessed pusher have the newer dials. I'd describe the older dials as matte with a pinkish hue, whereas the newer dials have more of a brighter metallic sheen with no pink tones. Here are some pics comparing the two dial types.
