The silver-tinged blue dial of SLGB003 is inspired by the frozen landscapes of the Kirigamine Highlands, where winter’s frost transforms the trees into delicate sculptures of ice. Finished with expert craftsmanship, the dial’s soft, crystalline texture captures the essence of this natural phenomenon. The tempered blue seconds hand glides smoothly across the surface, a hallmark of Spring Drive, bringing a natural sense of time’s quiet flow.
The design language of SLGB003 follows Grand Seiko’s Evolution 9 (E9) design philosophy, rooted in the 44GS of 1967. Broad, faceted hands and bold grooved markers ensure exceptional legibility, while the interplay of Zaratsu-polished and fine hairline finishes highlights the case’s sharp yet refined geometry. With a diameter of 37mm, the watch offers a perfectly balanced fit. The case is crafted from high-intensity titanium, providing both durability and a lightweight feel on the wrist. A newly developed bracelet with a three-step micro-adjustment clasp allows for tool-free sizing in 2mm increments, ensuring a precise and comfortable fit.
At the heart of SLGB003 is the groundbreaking Spring Drive Caliber 9RB2, a movement that achieves an unprecedented level of accuracy. With an annual deviation of just ±20 seconds, it carries the U.F.A. (Ultra Fine Accuracy) designation, representing the pinnacle of precision in a mainspring-powered watch. This innovation is achieved through meticulous engineering, including a specially aged quartz oscillator, a highly efficient integrated circuit, and a vacuum-sealed regulation system that ensures stability over time. The movement’s beauty is visible through the exhibition case back, where finely polished bevels and jewel-set bridges reflect the exceptional craftsmanship of the Shinshu Watch Studio.
Designed in the Evolution 9 Style, the SLGB003 refines Grand Seiko’s ideals of beauty, legibility, and comfort in a smaller 37mm case. The striking form blends distortion-free Zaratsu polishing with delicate hairline finishes for a soft glow, while bold, grooved indexes and powerful hands enhance readability.
The silver-tinged blue dial of SLGB003 evokes the crisp beauty of a frost-covered landscape, inspired by the frozen trees of the Kirigamine Highlands. Its finely textured surface shimmers with depth and clarity, while the tempered blue seconds hand glides effortlessly, mirroring the quiet flow of time in nature.
The bracelet's newly developed three-step micro-adjustment clasp enables tool-free sizing in 2mm increments, ensuring a perfect and comfortable fit on the go.
Crafted from high-intensity titanium, the case and bracelet are not only 30% lighter than stainless steel but also more resistant to scratches, ensuring durability without compromising comfort. Due to the hardness and unique properties of titanium, Grand Seiko has adapted its Zaratsu polishing technique to achieve the same crisp edges and flawless reflections found in its steel cases, resulting in a striking combination of durability, lightweight comfort, and a beautifully refined finish.
Caliber 9RB2 introduces the Ultra Fine Accuracy (U.F.A.) designation, achieving an extraordinary annual precision of ±20 seconds—the most accurate mainspring-powered movement ever created (as of April 2025, based on Grand Seiko’s research). This exceptional performance is made possible by an aged quartz oscillator, a newly developed integrated circuit, and a vacuum-sealed regulation system that ensures long-term stability. With a 72-hour power reserve and 34-jewel construction, 9RB2 embodies Grand Seiko’s relentless pursuit of innovation and precision.
