Issey Miyake‘s Roku watch collaboration with industrial designer Konstantin Grcic is set to receive a shot in the arm. The understated timepieces have emerged in a limited edition navy edition, elevated by a wide leather strap at the rear.

Known for his work with clients like Vitra and Flos, the Berlin-based Grcic is in high demand. His work for Miyake’s watch line intelligently flips the sub-labels name, “Roku,” on its head, yielding a case with six points. This limited version takes on a navy hue, expanded underneath with a slab of tonal calf leather. The matching strap is attached to a stainless steel case realized with a quiet, numeral-free design that emphasizes the branding and simple indices.

“Roku draws upon the correlation between two geometries: a hexagon and a circle,” Grcic explained. “The six-sided watch case relates to the 12 hours chronometry. The round dial resembles the circular movement of time. Two strong shapes that interplay with each other. Just like the notion of time: The continuous passing of hours/minutes/seconds on the one hand, the punctuation of certain events on the other.”
