I like the Lumen series - but I think the Zeitwerk was the peak of the species and that Lange perhaps ought to have stuck with that.
I much prefer the argenté dials - and, by tradition, black dials on their chronographs.
First generation vs. second generation Datograph…? Well, surely that’s a whole new thread! I have the pink gold, second gen. Dato - but, yeah: the OG will always be the OG.
