OK, so I have looked at the specs, pics, etc between josh's 2 black ceramic J12's. Specifically, CHA10013 and CHA10001.
The only thing I can find that maybe the issue is the date font and I thought at first it was an update, but actually the cheaper one (10013) was actually added at a later date, and is newer.
Anyway, if anyone has a clue as to what the difference is, I would love to know, links follow:

CHA10001: http://watchwindersworld.com/cha10001-blac...rtz-p-1775.html
Thanks!
