Inside, the SLGB003 is powered by Grand Seiko’s latest in-house automatic Spring Drive Caliber 9RB2. This movement sets new standards for accuracy, achieving Ultra Fine Accuracy (U.F.A.) of ±20 seconds per year—the highest for a mainspring movement as of 2025. Its precision stems from a combination of an aged quartz oscillator, an innovative integrated circuit, and a vacuum-sealed regulation system that minimizes environmental impact. You’ll appreciate the regulation switch, which allows for after-sales adjustments to keep the watch performing at its peak over time. The movement features 34 jewels and offers a 72-hour power reserve, supporting long-term reliability and consistent performance. The development of Spring Drive technology spans over 40 years, reflecting the brand’s dedication to innovation and mastery in watchmaking. Additionally, the precision of the watch’s movement aligns with the high standards of accuracy established by the Spring Drive technology.
Durability comes from the high-intensity titanium case, which also boasts a 10 ATM water resistance rating, making it suitable for daily wear and exposure to water. The sapphire crystal is box-shaped and treated with an anti-reflective coating on the inner surface, ensuring clarity and scratch resistance. A see-through screw-down case back provides a view of the expertly finished movement, highlighting the craftsmanship behind the watch. Magnetic resistance of 4,800 A/m shields the movement from daily magnetic fields, preserving accuracy and function.
The bracelet matches the case in titanium, offering a lightweight yet sturdy feel. Its three-step micro-adjustment clasp can be easily resized in 2mm increments without tools, providing a perfect fit throughout your day. The three-fold clasp with push-button release ensures secure closure and effortless wear. The low center of gravity design improves comfort and stability on your wrist, making it ideal for extended wear. The dial features a central hour, minute, and second hand, along with a date window that’s clearly visible. The power reserve indicator, positioned on the movement side, maintains the dial’s minimalist aesthetic. Thanks to Spring Drive technology, the smooth motion of the seconds hand symbolizes the natural flow of time, blending precision with elegance effortlessly.
