Marking the conclusion of a three-part collaboration, this watch applies a specific mid-1980s design language to the 6900 silhouette.The matte "Dusty Blue" resin and cream-accented dial directly referenced the vintage Casio PT-1 synthesizer, the 1st ever keyboard owned by Mayer.
G-Shock, a division of Casio, effectively created the "tough watch" category upon its debut in 1983. The brand was born from engineer Kikuo Ibe's "Triple 10" concept: a watch capable of surviving a 10-meter fall, with 10-bar (100m) water resistance, and a 10-year battery life. This was achieved through a revolutionary hollow case structure where the timekeeping module "floats" within a protective urethane bezel, isolating it from external shock.
While initially a purely utilitarian instrument, G-Shock's absolute durability made it a foundational tool for military and sports use. It has since evolved into a global cultural phenomenon, embraced by streetwear, fashion, and art, with its myriad collaborations and iterations making it a distinct and accessible collecting category.
