A compact size Spring Drive UFA, showcasing the shimmering surface of Lake Suwa.

Inspired by the tranquil waters of Lake Suwa, the SLGB015 features a beautifully textured blue dial that reflects the lake’s calm surface and natural beauty. Situated near the Shinshu Watch Studio in Shiojiri, where Grand Seiko’s renowned Spring Drive timepieces are meticulously crafted, Lake Suwa serves as a fitting inspiration for this elegant and highly precise creation. 

At the heart of the watch is the Spring Drive U.F.A. Caliber 9RB2, an innovative movement that delivers exceptional performance with an extraordinary annual accuracy of ±20 seconds. The movement also provides an impressive 72-hour power reserve, ensuring reliable operation for up to three days when fully wound.

The case and bracelet are crafted from Ever-Brilliant Steel, a premium stainless-steel alloy celebrated for its brighter appearance and outstanding corrosion resistance. At 37mm in diameter, this is the smallest dimensions for any self-winding Spring Drive model. Combining advanced Spring Drive technology, superior materials, and nature-inspired design, this smaller-sized Grand Seiko luxury timepiece exemplifies the precision, craftsmanship, and elegance sought by discerning watch collectors and enthusiasts.
