The Seiko Presage Classic Series expands its artistry with two captivating new models, deeply rooted in Japanese culture and history. These timepieces are inspired by 'Ai-iro' (Indigo Blue), a color that holds immense significance and beauty across the nation.
For centuries, Ai-iro has been synonymous with Japanese tradition. During the age of the Samurai, this striking indigo was revered as a "lucky color," symbolizing strength and resilience. Later, as Japan opened to the world in the Meiji era, visitors were so struck by the ubiquitous presence of this color throughout the urban landscape that they christened it "Japan Blue."
These new watches capture the profound depth and subtle variations of this celebrated hue. With their refined dials, these models offer collectors not just a timepiece, but a piece of Japanese heritage—a sophisticated accessory that carries the powerful, elegant story of a color beloved for centuries.
