Those tiny day-night subdials were an eyesore, and Lange did a good job correcting them. Only one more to go, the miniature seconds subdial. Would be much better if Lange did something with that.
My only real quibble with the update is that the white gold, black dial version doesn't have a dial color-matched date wheel. Not so bad when in the zone of two-digit dates, but from the first to the ninth of the month, the empty date window is lame on a dark dial (I have the same issue with the L1 and its other variations).
Cheers,
