Grand Seiko Evolution 9 Spring Drive U.F.A. Ushio 300 Diver
Grand Seiko Evolution 9 Spring Drive U.F.A. “Ushio 300” Green The pinnacle of Japanese precision and design The Grand Seiko SLGB025 is not just a diving watch; it is a manifesto of Japanese haute horlogerie. As an exclusive piece for Grand Seiko Boutiques and Salons, this model represents the perfect union between extreme functionality and poetic aesthetics inspired by the Japanese archipelago.
“Ushio” Dial: The Calm of Coastal Waters The visual heart of this watch is its stunning green dial with the “Ushio” (tide) pattern. Its gradient design captures light in a unique way, evoking the serenity of Japan’s shallow coastal waters. The faceted indices and bold hands, characteristic of the Evolution 9 Style, ensure absolute legibility, while its ceramic bezel adds sophisticated visual depth and durability.
Caliber 9RB1: Ultra Fine Accuracy (U.F.A.) Beating inside is the revolutionary Spring Drive 9RB1 movement. Thanks to the U.F.A. (Ultra Fine Accuracy) designation, this watch achieves a phenomenal precision rate of ±20 seconds per year, making it one of the most accurate mainspring-driven movements in the world. The second hand glides with a fluid, silent motion, reflecting the natural flow of time.
Cutting-Edge Ergonomics and Materials Built entirely from High-Intensity Titanium, the SLGB025 is 30% lighter than steel and highly resistant to corrosion and scratches. With a diameter of 40.8 mm, it stands as the most compact diver in the collection, offering a perfect fit and unparalleled comfort thanks to its low center of gravity.
Professional Performance Under the Sea Designed for exploration, it offers water resistance of 300 meters. Its technical bracelet includes a locking extension clasp with micro-adjustment, allowing the watch to be easily adapted even over a diving suit. Every detail, from the screw-down crown to the powerful Lumibrite, has been engineered for uncompromising performance in the most demanding environments.
