Casiophile put together this nice guide, and it's really worth checking out if you haven't read it already. The WW-5100 model came out in 1983, and the WW-5300 was released in 1984. These are both similar to the DW-5000, but both series have faded away into ancient G-Shock history. They're currently some of the rarest models out there.
