Casio G-Shock 40th Anniversary Clear Remix DW-6940RX-7D

Express yourself in no uncertain terms with the G-SHOCK 40th anniversary Clear Remix lineup — popular G-SHOCK designs deconstructed with see-through components for the clearest look yet. 
See-through materials for the band, case, dial, LCD, and buttons provide a behind-the-scenes view of the module substrate printed with the G mark and G-SHOCK logo. The case back features the Eric Haze-designed 40th logo, and the band loop is engraved with four stars in a nod to this special anniversary. 
These details and the first-ever use of a see-through case made of clear glass fibre diamide deliver a singular design worthy of an exceptional limited-edition G-SHOCK. 
The new lineup includes watches modeled after multiple iconic G-SHOCK timepieces: the very first G-SHOCK, the DW-5000; the classic digital DW-5600; the DW-6900 with distinctive front button design; or the GA-2100/GMA-S2100 or the GA-110/GMA-S110, which can be worn on their own or as part of a matching set.
