I found this neat watch while perusing G-Shock Wiki:
It looks like a mirrored DW9000 module inside a DW6600/6900 bezel.
I can't find any information on it, was it produced for long? Was it ever popular? I'd love to get my hands on one, it looks like a nice compromise between the sparse 6600 display and the three-eyed devil. And I bet it would rock on a Zulu/NATO.
