Features

The shimmering surface of Lake Suwa, imagined through Spring Drive UFA.

Inspired by the serene beauty of Lake Suwa, the Grand Seiko Spring Drive U.F.A. SLGB013 features a striking blue dial with a textured pattern that captures the gentle movement and reflective surface of the lake. Located near the Shinshu Watch Studio in Shiojiri, where Grand Seiko Spring Drive timepieces are meticulously crafted, Lake Suwa serves as a lasting source of inspiration for the brand’s nature-driven designs. 

Powering this exceptional timepiece is the Spring Drive U.F.A. Caliber 9RB2, an advanced movement that delivers remarkable precision with an annual accuracy of ±20 seconds. Designed for collectors and enthusiasts who value both innovation and performance, the movement also provides a substantial 72-hour power reserve when fully wound.

The case and bracelet are crafted from Ever-Brilliant Steel, a premium stainless-steel alloy known for its brilliant white luster and superior corrosion resistance. Combining cutting-edge Spring Drive technology, refined Japanese craftsmanship, and a dial inspired by one of Japan’s most picturesque landscapes, this Grand Seiko exemplifies luxury Japanese watchmaking and is a distinguished addition to any fine watch collection.
