Features

A dial inspired by the crystal-clear blue-green waters of the breathtaking Atera Valley, for the Spring Drive UFA.

Inspired by the pristine natural beauty of Nagano Prefecture, this Grand Seiko Spring Drive U.F.A. reflects the region’s majestic mountains and crystal-clear rivers. The intricately crafted dial draws inspiration from the enchanting waters of the Atera River, located near the Shinshu Watch Studio in Shiojiri, where Grand Seiko Spring Drive timepieces are meticulously created. Featuring a stunning blue-green color palette and a refined gradient finish, the dial captures the river’s remarkable clarity and depth through exceptional Japanese craftsmanship.

At its core is the advanced Spring Drive U.F.A. Caliber 9RB2, a breakthrough movement that delivers extraordinary precision with an annual accuracy of ±20 seconds. Designed for discerning watch enthusiasts and collectors, the movement also provides an impressive 72-hour power reserve when fully wound.

The case and bracelet are crafted from Ever-Brilliant Steel, a premium stainless-steel alloy prized for its bright, elegant appearance and outstanding corrosion resistance. Combining cutting-edge Spring Drive technology, nature-inspired design, and Grand Seiko’s renowned attention to detail, this exceptional luxury timepiece is a distinguished addition to any fine watch collection.
