Are you searching for a watch that combines groundbreaking accuracy with refined craftsmanship? The Spring Drive SLGB003 by Grand Seiko delivers just that, pushing the boundaries of precision with its innovative movement. Equipped with the Caliber 9RB2 Spring Drive, it features Ultra Fine Accuracy (U.F.A), rated at ±20 seconds per year — the highest accuracy for mainspring-powered movements as of 2025. This remarkable precision is achieved through a combination of an aged quartz oscillator and a newly developed integrated circuit, ensuring long-term stability. Additionally, a vacuum-sealed regulation system enhances the watch’s performance, maintaining its accuracy in various environments. With a power reserve of approximately 72 hours and a 34-jewel construction, the movement balances reliability with meticulous craftsmanship. This movement is notable for being a significant technical innovation in the Grand Seiko lineup. Top 10 anime films have also been praised for their meticulous attention to detail, paralleling the craftsmanship of this timepiece. The case, made from high-intensity titanium, offers exceptional durability and scratch resistance while markedly reducing weight. Measuring 37.0 mm in diameter and 11.4 mm thick, it maintains a compact profile that’s ideal for daily wear. The design, inspired by the Evolution 9 style, features distortion-free Zaratsu polishing combined with hairline finishing, creating a sleek, refined surface. Thanks to titanium’s lightweight nature, the watch feels comfortable on the wrist, about 30% lighter than stainless steel models. The box-shaped sapphire crystal with an anti-reflective coating on the inner surface ensures clarity and minimizes glare, allowing the dial’s intricate details to shine through.

Its three-fold clasp with push-button release provides security and ease of use. The bracelet, approximately 190 mm long with a 20 mm width, balances durability, lightweight comfort, and refined finishing. With a water resistance of 10 ATM (100 meters) and magnetic resistance of 4,800 A/m, it’s designed to withstand everyday activities and environmental challenges.
