The SLGB006 “Ice Forest at Dawn” captures the serene beauty of Shinshu’s winter forests as the first light of day strikes the frost-laden trees. Its black dial features gold-colored specks, evoking sun pillars formed by ice particles in the freezing morning air, creating a luminous, textured effect that recalls the natural phenomena of central Japan.
Powered by the Spring Drive Caliber 9RB2, Grand Seiko’s most accurate mainspring movement to date, the watch achieves ±20 seconds per year. Precision is ensured through a vacuum-sealed oscillator, a three-month aging process, and a thermo-compensated IC, while the regulation switch allows fine-tuning during service. The movement, visible through the exhibition case back, is adorned with a frost-inspired texture and an oscillating weight engraved with “Spring Drive Ultra Fine Accuracy.”
Encased in 18k yellow gold, the 40.8mm SLGB006 combines elegance with robustness, paired with a black crocodile strap and matching three-fold clasp. With a 72-hour power reserve and a restrained, luxurious profile, it is a refined expression of the Evolution 9 Style. Limited to 80 pieces, this watch is available exclusively at Grand Seiko Boutiques.
Designed in the Evolution 9 Style, the SLGB006 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.
A refined yellow gold expression of the Evolution 9 design, this limited-edition timepiece draws inspiration from the winter landscapes of Shinshu. Its black dial, illuminated with delicate gold specks, evokes the phenomenon of sun pillars rising through ice-laden forests at dawn, capturing a fleeting moment where light and frost converge in quiet brilliance.
Crafted in 18k yellow gold, the case follows the refined proportions of the Evolution 9 design, where polished and brushed surfaces interact to create depth and contrast. The result is a sophisticated expression of precious-metal craftsmanship, balancing elegance with a strong, contemporary presence.
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.
