The new “GT” watches were inspired by the “Grand Touring” automobiles for motor sports, Okuyama's field of expertise.

By fusing grace into the simple, unadorned automotive design, the functional elements of the GT automobiles—speed, distance, and time—are embodied in the mechanical watches.

As if heralding a grand adventure to places unknown, the new ISSEY MIYAKE Prestige Watches are ready to begin ticking.
