Grand Seiko Evolution 9 Lake Suwa Spring Drive U.F.A. – SLGB015

The Grand Seiko Evolution 9 Lake Suwa Spring Drive U.F.A. SLGB015 is a refined expression of Japanese artistry, precision, and innovation. Inspired by the tranquil beauty of Lake Suwa near the Shinshu Watch Studio, the beautifully textured blue dial captures the shimmering ripples and luminous reflections that dance across the lake’s surface. Enhanced by a subtle radial finish and the signature glide of the Spring Drive seconds hand, the dial evokes the serene passage of time in nature.

Housed in a perfectly proportioned 37mm case—the most compact self-winding Spring Drive model in the Grand Seiko collection—the SLGB015 offers exceptional comfort while maintaining a sophisticated presence on the wrist. Crafted from Grand Seiko’s exclusive Ever-Brilliant Steel, the case and bracelet showcase remarkable corrosion resistance and a brilliant luster that enhances the brand’s renowned Zaratsu finishing.

At its heart is the groundbreaking Spring Drive U.F.A. Caliber 9RB2, delivering an extraordinary annual accuracy of ±20 seconds and an impressive 72-hour power reserve. A newly developed three-step micro-adjustment clasp ensures a precise fit without tools, enhancing everyday wearability. Combining advanced watchmaking technology, elegant proportions, and a deep connection to Japan’s natural beauty, the SLGB015 exemplifies Grand Seiko’s pursuit of the ideal luxury timepiece.
