The movement is constructed and finished to exactly the standard you would expect from Lange, which is to say, it's immaculate. The 3/4 plate aesthetic is not necessarily to everyone's taste, as it can seem rather austere in comparison to a full-bridge movement, but it is consistent with the general design of movements in German watchmaking. Modern manufacturing methods mean that one advantage 3/4 or full-plate movements had over bridge calibers – greater rigidity, which was an aid to rate stability – no longer generally obtains, but it is more difficult to assemble a 3/4 plate movement than a bridge caliber (I remember, many years ago, trying to reassemble the first 3/4 plate American pocket watch I'd ever worked on; there was swearing) so if you like the idea of the exercise of craft for its own sake, Lange remains a very appealing manufacturer. A. Lange & Söhne movements on a certain level, are the art of the unnecessary in the best possible way, although they're also manufactured to a high functional standard (Lange watches anecdotally seem to be, reliably, extremely accurate) and they combine excellence in craft and excellence in functional integrity in a way you see in very few watches these days.
