Just nitpicking, but judging from the photo, it seems like the black center was haphazardly centered and painted. Unless it is an optical illusion, this is a "'defect" that I would not accept from any new wheel, much less an esteemed manufacture such as Alpina.
The original Alpina wheel manufacture (Ronal) has never been or will be considered a "premium wheel manufacture" and I think their inferior paint finishes show. Many Alpina rims that I've seen that still have their original paint on them, have a flat and dull appearance to them. Most likely, clearcoating was not used during their painting process, hence the relatively quick deterioration of the paint.
Don't know whether this was an option, but Alpina should have selected OZ as their makers of their wheels, in place of Ronal. The paint quality on their rims is much superior than Ronal wheels. The finish on my OZ made 15" 20 spoke rims, which I bought new back in 1990 still appears factory new after a good washing.
JMHO, the "contained" black centers look much better than the "extended" black centers. Whether this is factory original or not, to me, it is irrelevant.
