There are total eleven G-Shock released in Japan in March 2011. These part inclusive of one limited edition DW6900, three new model GD-200 and three new model GDF-100. It seems that GDF-100 alti-thermo model is replacing the master-G RISEMAN. I would prefer the RISEMAN as the design of this new model looks too retro. The limited edition DW6900 is so simple, collect it if you are fans of KRINK New York.
