This is a special model commemorating the 30th anniversary of the 6900 series, a long-selling iconic model representing G-SHOCK since its birth in 1995. The front button, a design icon of the 6900 series, is metalized, and the "G" mark engraved on the mirror-finished surface exudes a powerful presence. When the backlight is illuminated, "SINCE 1995," the debut year of the 6900 series, appears on the LCD. Furthermore, the back cover, engraved with the SHOCK RESIST mark, features 30 star marks commemorating the 30th anniversary of the 6900 series. The packaging incorporates three colors: black, red, and yellow, and pays homage to the DW-6900H package design, which features the "G" mark as a motif. Biomass plastic, which is expected to contribute to reducing environmental impact, is used for the main resin parts such as the bezel and band. This is a special design to celebrate the anniversary year of the 6900 series.
