Grand Seiko Evolution 9 Spring Drive U.F.A. SLGB003
The Grand Seiko SLGB003G “Ice-Forest” is a groundbreaking timepiece that combines serene aesthetics with the pinnacle of Spring Drive technology. Its delicately textured silver-blue dial evokes the frost-covered forests of the Kirigamine Highlands near the Shinshu Watch Studio, while the tempered blue seconds hand glides smoothly in silent precision. Housed in a 37 mm high-intensity titanium case—the smallest ever to contain a 9R-series movement—it offers lightweight comfort at just 100 g, with a durable three-fold clasp featuring tool-free micro-adjustment for a custom fit.
At its core is the new Spring Drive 9RB2 U.F.A. (Ultra Fine Accuracy) caliber, delivering ±20 seconds per year precision—the most accurate mainspring-driven watch in the world as of 2025. This movement features aged quartz oscillators, a low-power IC with environmental compensation, a vacuum-sealed sensor for stability, and a regulation switch for post-purchase fine-tuning, all while maintaining a 72-hour power reserve. Finished with a box-shaped sapphire crystal, screw-down crown, sapphire case-back, and mirror-polished surfaces that echo the frost motif, the SLGB003G is both a technological milestone and a refined tribute to Japanese nature and craftsmanship.
