High-beat precision and three days of power reserve come together in the Tentagraph, with a dial inspired by Mt. Iwate.

The Evolution 9 Style represents the essence of Grand Seiko’s design philosophy, harmoniously blending Japanese aesthetics with refined craftsmanship. Based on this design language, this model adopts a form that ensures intuitive usability and excellent operability in any situation. The tachymeter bezel is made of highly scratch-resistant ceramic, allowing it to maintain its refined appearance over time.
The dial design follows the Evolution 9 Style and adopts a traditional chronograph layout. The distinctive hour and minute hands, along with the indexes with Lumibrite, are positioned with minimal clearance to enhance not only legibility during time measurement but also overall time readability. Mt. Iwate, visible from the Grand Seiko Studio Shizukuishi, serves as a source of inspiration and a spiritual anchor for the craftspeople. The dial combines a delicate pattern inspired by the mountain’s surface with a transparent blue tone, expressing the starry sky that spreads above its summit. This design reflects a vision of reaching the pinnacle of the ideal chronograph.
