Designed to embody beauty and performance, this watch sets a new standard for accuracy and craftsmanship. If you continue exploring, you’ll discover even more about what makes this watch exceptional.
Grand Seiko has introduced the SLGB003, a watch that combines precision engineering with elegant design. The case, crafted from High-Intensity Titanium, is 37mm in diameter and 11.4mm thick, making it compact and comfortable for daily wear. This titanium material is 30% lighter than stainless steel and highly scratch resistant, guaranteeing durability without sacrificing comfort. Its water resistance is rated at 10 ATM, allowing you to confidently wear it during everyday activities and light water exposure. The dial, inspired by the frozen landscapes of the Kirigamine Highlands, features a silver-tinged pale blue hue with a finely textured surface that shimmers with depth and clarity. The box-shaped sapphire crystal, coated on the inner surface with anti-reflective treatment, guarantees excellent legibility and resilience against glare. The case’s design adheres to the Evolution 9 Style, emphasizing crisp lines and contrasting finishes, which enhance both aesthetics and ergonomics. A quote from visionaries on the importance of precision can remind us how details, like those in watchmaking, can significantly impact our lives. Inside, the SLGB003 houses the innovative 9RB2 Spring Drive caliber. This automatic movement offers an impressive 72-hour power reserve, so you won’t need to wind it frequently. What truly sets it apart is its Ultra-Fine Accuracy (U.F.A.) of ±20 seconds per year, the highest precision for mainspring-powered watches as of April 2025. This exceptional accuracy results from a combination of advanced features, including an aged quartz oscillator, a vacuum-sealed regulation system, and an integrated circuit that stabilizes timekeeping. The movement’s 34 jewels enhance durability and ensure smooth operation, supporting functions like hours, minutes, seconds, and date display. The bracelet matches the case’s High-Intensity Titanium, emphasizing lightweight durability. Designed in the Evolution 9 Style, it features Zaratsu polishing, which delivers distortion-free finishing and a soft glow. The three-fold clasp, equipped with a push-button release, incorporates a newly developed micro-adjustment system that allows you to fine-tune the fit with 2mm increments without tools. This ensures a perfect, comfortable fit during extended wear. The combination of Zaratsu polishing and a hairline texture on the bracelet creates an elegant, refined aesthetic that complements the watch’s overall design. Aesthetically, the SLGB003 embodies Grand Seiko’s focus on beauty, clarity, and comfort. The bold, grooved indexes and powerful hands enhance readability, with the absence of lume preserving a clean look. The seconds hand, painted in tempered blue, glides seamlessly across the dial, symbolizing the quiet flow of time in nature. The textured dial surface catches light delicately, mimicking frost-covered landscapes. The case is finished with Zaratsu polishing, giving it crisp edges and mirror-like reflections, further elevating its sophisticated appearance. Overall, the SLGB003 presents a harmonious blend of technical excellence and understated elegance, making it a remarkable addition to Grand Seiko’s collection.
