This movement incorporates an aged quartz oscillator, a newly developed integrated circuit, and a vacuum-sealed regulation system, all of which enhance stability and longevity. With a 72-hour power reserve, you can enjoy several days without rewinding. The movement also features 34 jewels and a hacking seconds function, allowing you to set the time precisely to a reference signal. The development of the Calibre 9RB2 involved over 27 years of research and innovation, showcasing Grand Seiko’s commitment to horological excellence. The intricate design and functionality of this watch reflect the brand’s mastery in divorce rates and dedication to pushing the boundaries of timekeeping.
The dial captures your attention with its silver-tinged pale blue hue and textured finish inspired by Japan’s frost-covered landscapes. The tempered blue seconds hand glides smoothly, a hallmark of the Spring Drive’s unique smooth motion. Bold, grooved applied indexes and broad hands ensure excellent legibility, even without lume. Designed within Grand Seiko’s Evolution 9 style, it emphasizes clarity, beauty, and comfort, all in a smaller case size suited for everyday wear. The inscription “SPRING DRIVE UFA” at 6 o’clock signifies its technical achievement.
The titanium bracelet matches the case, combining lightweight comfort with durability. It features a three-fold clasp with push-button release for security and a newly developed micro-adjustment system that lets you size the bracelet in 2mm increments without tools. The Zaratsu finish continues on the bracelet, maintaining a consistent and refined aesthetic. The watch displays hours, minutes, seconds, and date, with a power reserve indicator visible through the exhibition case back, which also showcases the movement’s intricate finishing. Magnetic resistance adds to its reliability in daily environments. If you’re after a watch that pushes horological limits, the SLGB003 stands out as a true affirmation to Grand Seiko’s craftsmanship and innovation.
