In the summer of 2006 Casio
released the first Jam'in Color models. This were the DW-6900 versions. In
October 2006 the line was extended with two G-5500 and two G-9000 models.
The Jam'in Color series were
inspired by the youth culture, where camouflage patterns are very popular.
The watchbands (and the bezels of the DW-5500MC and DW-6900MC models) are a
mix of two colors, like a Jam Session. Since the two tones of resin are
mixed, every pattern on the watch is unique.
