Standard California G-SHOCK 20th Anniversary Model New, unused item. This latest piece, concluding Standard California's 20th anniversary project, selects the DW-5700C, an early round basic G-SHOCK model born in 1987, as its base. Although the DW-5700C was not released in Japan, it became a legendary model with worldwide popularity, partly due to its adoption by famous musicians. The DW-5750, a complete revival of the DW-5700C for domestic sale, is the base model for this collaboration.
