Generally, watches have standard design elements, such as the crown hole position, mechanism fitting, and back cover design. In search of a yet-unseen design that transcends those preconceptions, Yamamoto visited the MINASE watch factory with Suzuki. There, Yamamoto caught sight of technicians carefully polishing the case surfaces with technique and passion. Convinced that this production line would allow him to pursue an innovative design without being constrained by mass production, Yamamoto gave a lecture to the cutting and polishing technicians at the MINASE watch factory titled "What is Design?" so as to build rapport. Even if a truly new, innovative design is introduced, it cannot be realized without the technicians who can make it possible. With the aim of delivering a design that makes MINASE's unique techniques appeal to customers, Yamamoto and Suzuki hit it off immediately. Without this fateful encounter, HORIZON and WINDOWS—mavericks in the history of watches— would never have been born.
