I just got my ceramic JF 21j and the watch head is fine....but the bracelet is crap. And i'm not talking just about the SEL (which is also crap) but the overall feel of the bracelet. It feels light and fake squeaky, nothing in comparison to my noob GMT bracelet which feels solid and its got some more weight to it.
But then again, that is just my opinion
