This is my mysterious
DW-610. It was released December 1994. At the same time the BG-610 was
released. Probably the first Baby-G model as we know them now. Actually the
first Baby-G was the DW-500, a smaller version of the DW-5600.
The first time I
saw one was in 2001. One of my students,
Thijs, was wearing one. He had bought it
at the jeweler that's also my Casio dealer. He became one of the first
G-People of G-Peopleland. I don't know when this one was released, but
according to the animations in the display and the spinning G, it seems this
is a sort of study model for the Baby-G series. It took me at least 2 years
to find this model, so I think it is rare.
