This special edition model done in collaboration with Eminem celebrates the 30-year anniversary Casio G-SHOCK. Features of this all-black model include a large red ’3′ on the watch face and a red printed outline of the Detroit skyline on the watchband, and the rapper's signature can be seen on the back cover. Comes in a matching black box with both the red outline and Slim Shady’s signature. The G-SHOCK Big Case GD-X6900MNM-1JR will release this December at select retailers.
