Shin Azumi is a London-based, Japanese designer of everything from stools to salt'n'pepper shakers. Azumi's thoughtful attention to detail has garnered him several awards worldwide, including the Jerwood Applied Arts Prize and the Blueprint 100% Design Award.

With Azumi's ingenious Sol watch, his design higlights solar power. "Thinking about a typical solar watch, the solar cell is often disguised or hidden away from view. I wanted to put focus on the solar cell as a design feature to express its importance," Azumi said. Using cool colors and out-of-the-box thinking, Azumi amped up Sol watch's innovative silhouette—which adds to its own battery life by absorbing energy from the sun.
