Grand Seiko Evolution 9 SLGA025 'Atera Valley'
Nagano Prefecture, where Spring Drive watches are manufactured, is home to a number of mountains rising over 3,000 meters. The countless rivers that flow from these mountains have, over many years, created a lush, natural environment. The Atera River carves out a deep ravine called the Atera Valley, known for its breathtaking beauty. Using the clear, emerald-green waters of the Atera River as a motif, the dial conjures the image of a stream so clear that one can see the bottom, as well as the rich, natural harmony of summertime. At the heart of this watch is the Spring Drive 5 Days Caliber 9RA2. This movement provides up to 120 hours (5 days) of power when fully wound, as well as an average accuracy of Ā±10 seconds per month, an astounding achievement for a watch powered by a mainspring.

About Grand Seiko
Grand Seiko emerged in 1960 as a high-end watch line from Seiko, aiming to challenge Swiss dominance in luxury watchmaking. The brand quickly established itself with Japan's first chronometer-grade watch and later gained renown for its innovative Spring Drive technology, which combines the best of automatic and quartz movements. In 2017, Grand Seiko became an independent entity, solidifying its position in the luxury watch market.
The brand's design philosophy, known as the "Grammar of Design," was established in 1967 with the Grand Seiko 44GS. This aesthetic approach emphasizes legibility, refined appearances, and distinctive features like multi-faceted markers and hands, a half-recessed crown, and the meticulous Zaratsu polishing technique. Grand Seiko continues to push boundaries in watchmaking, as evidenced by recent innovations like the "Kodo Constant-Force Tourbillon," while maintaining its commitment to precision engineering and unique design language.
