The SLGB005 Ice Forest “Violet Dawn” draws inspiration from the frost-covered forests of Shinshu, where the first light of day casts a soft violet glow across the landscape. The dial’s crystalline texture, created through refined finishing techniques, reflects this natural scene as it gradually brightens toward the center. Against this backdrop, the silver-toned seconds hand glides smoothly, a signature of Spring Drive that mirrors the quiet passage of time.
The design follows Grand Seiko’s Evolution 9 philosophy, an interpretation of the Grand Seiko Style first expressed with the 44GS in 1967. Broad, faceted hands and deeply grooved markers ensure clarity at a glance, while Zaratsu-polished and hairline finishes highlight the case’s sharp yet refined form. The 37mm case is made from Ever-Brilliant Steel, a material celebrated for its durability, corrosion resistance, and bright hue. Its bracelet is paired with a clasp featuring an 18k rose gold emblem. This clasp does not include a micro-adjustment feature.
Powering the SLGB005 is the Spring Drive Caliber 9RB2, a movement with an impressive ±20 seconds per year accuracy, earning the Ultra Fine Accuracy designation. This performance is achieved through a specially aged quartz oscillator, a low-power integrated circuit, and vacuum-sealed components that ensure long-term stability. Visible through the sapphire crystal case back, the movement features frosted finishing that recalls Shinshu’s winter landscapes, with jewels that sparkle like stars above the mountains. The oscillating weight is engraved with “Spring Drive Ultra Fine Accuracy,” underscoring this achievement.
Designed in the Evolution 9 Style, the SLGB005 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 stunning violet dial color deepens the aesthetic impact, adding a vivid contrast that highlights the harmonious balance of the Evolution 9 design.
The dial of the SLGB005 Ice Forest “Violet Dawn” captures the fleeting beauty of dawn in the frost-covered forests of Shinshu. As the first light of morning brushes the frozen trees with a soft violet glow, the crystalline texture reflects this quiet transformation. A subtle gradation toward the center evokes the gradual awakening of nature as night gives way to day.
The SLGB005 is crafted from Ever-Brilliant Steel, a superior alloy renowned for both its brightness and its exceptional resistance to corrosion. This advanced material not only ensures lasting durability but also enhances Grand Seiko’s renowned Zaratsu polishing, allowing the case to display a distortion-free mirror finish that plays beautifully with light and shadow.
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.
