Casio G-Shock DW-6640RE-1DR Digital

Join the 40th anniversary celebrations marking G-SHOCK milestones with a selection of signature revivals in solid, time-tested all-black.

In homage to the brand’s evolution, these special designs  iconic models from the past with their names hot-stamped on the band to textural, indented effect. On the DWE-5657, DW-6640, and GA-2140, a side button is engraved with a star in a nod to the 40th anniversary, as is the GA-114 with a star printed on the watch glass.

The band and bezel of every model in the line are made with bio-based resins. The 40th anniversary logo designed by Eric Haze is engraved on the case back, and also appears in silhouette when the light button is pressed on the DWE-5657 and DW-6640. With four stars for 40 engraved on the band loop and other special details, these limited-edition timepieces are heirs to G-SHOCK history.
