I just can't get enough of them. It seems that only the clear units suffer from yellowing but when (if) they end up yellowing, it's simple to dye them a nice shade of orange, blue, red, or even yellow. Worse case gray.
I got my wife a new dolphin and whale aqua blue jelly Baby G which she enjoys and just picked up this one...below, which matches.
CASIO G-SHOCK DW-6900 W.C.C.S VINTAGE EXCELLENT - eBay (item 220638293956 end time Aug-08-10 21:56:07 PDT)
HOw'd I do? I can't believe I snagged this for such a good price.
I also picked up a DW6925E-7 bezel and band for my Zombie Killer, which may or may not look good, but I just love the jelly look, and it may go better with the white resin of the WCCS too.
I'm looking forward to the arrival of the DW5025 Ocean Gray I just picked up on the sales forum too, although I'm a little concerned about legibility of the mirror in daylight with all the reflections that I think will show up.
Show me your jellies!
