This is an after though mistake correction G-Shock
That case was originally intended for the DW-5030C "Resist Black" of April 19th. The more I think about it, the more convinced I am of that.
The DW-5030C was shipped in a cheap paper box. The very cheapest of all G-Shock packaging. That is a severe and ignominious break with tradition. I can only conclude that something went horribly awry. I do not want to think that some sort of "new-blood" has taken over at G-Shock and has so little respect for tradition and heritage that they would sully and shame the prestige of the original DW-5000 by choosing to ship the 30th Anniversary edition of it in a cheap paper box.
Something went terribly wrong and the chest-style cases were not ready in time to ship out with the DW-5030C, so now CASIO produces this late-comer after-thought single (not part of any collection) DW-6930 only so that they can get rid of the bare aluminum cases that were most likely supposed to have been colorized black & copper but never made it through that stage of production.
This is only my theory since I don't have an information source inside CASIO, but it sure makes a lot of sense when you look at all the signs.
